Summary

Offshore wind turbines are ocean-based machines that harness natural wind to generate electricity. These turbines use the relatively strong winds over the water to rotate their blades, which power a generator to make electricity. The electricity travels through underwater cables to reach the land. There are two main types: fixed-bottom turbines, which are attached to the seabed in shallow waters (typically up to 60 meters deep), and floating turbines, which sit on platforms anchored in deeper waters. Offshore wind farms can produce more electricity than land-based wind farms because ocean winds are usually stronger and steadier than winds on land.

Deploying additional offshore wind turbines reduces CO₂ emissions by increasing the availability of renewable energy sources to meet electricity demand, therefore reducing dependence on fossil fuel-based sources in the overall electricity grid mix.

Deploy Offshore Wind is a Highly Recommended climate solution. It offers immense clean energy potential, but the race to scale it will test our ingenuity against the forces of nature, high costs, and competing uses of the seas.
Overview

Offshore wind turbines generate electricity by converting the energy from rotating turbine blades into electrical energy. The main components of offshore wind turbines include rotor blades, a tower to raise the rotor above the water, a nacelle hub that houses the generator and other key components, and a foundation that stabilizes the structure in the water. Offshore wind farms require additional infrastructure to transport generated energy through undersea cables to transformers and power substations before electricity can be supplied to consumers (Figure 1). To optimize performance, offshore turbines often use advanced control systems (e.g., yaw, pitch, and safety sensors).

Offshore wind turbines are often placed far from the coast to avoid causing noise pollution or taking up space on land. Foundations can be fixed to the seafloor (fixed-bottom) or floating depending on water depth and other characteristics, such as seabed topography and operational logistics (Afridi et al., 2024). Most offshore wind turbines operating in 2023 were fixed-bottom and limited to seafloor depths around 50 meters. Floating wind farms access wind resources over deeper waters, up to 1,000 meters (de La Beaumelle et al., 2023). 

Wind speeds over water are generally higher and more consistent than over land, which allows for more reliable and increased electricity generation. Potential power generated from offshore wind turbines is directly proportional to the swept area of the rotor blades and the wind speed cubed; a doubling of wind speed corresponds to an eightfold increase in power (U.S. Energy Information Administration [U.S. EIA], 2024). The maximum electrical power a turbine can generate is its capacity in MW. The average installed offshore wind turbine rating grew from 7.7 MW in 2022 to 9.7 MW in 2023 (McCoy et al., 2024), with the total global installed capacity reaching 75.2 gigawatts (GW) in 2023 (Global Wind Energy Council [GWEC], 2024).

The global weighted average capacity factor for offshore wind turbines has reached 41% (International Renewable Energy Agency [IRENA], 2024c) – an increase from 38% a decade earlier – driven by advancements in turbine efficiency, hub height, rotor diameter, and siting optimization. Our analysis assumed an offshore wind turbine capacity factor of 41% (IRENA, 2024c). Offshore wind capacity varies across regions due to differences in policy support, coastal geography, water depths, and infrastructure readiness. Electric power output can be converted to energy generated by multiplying capacity by the time interval and the capacity factor. For annual generation, we multiply by 8,760 hours for one year.

The main siting considerations for offshore wind farms are distance from shore and water depth, but energy output can also be impacted by atmospheric wind conditions as well as the configuration of turbines within a wind farm (de La Beaumelle et al., 2023; IRENA, 2024c). Protected areas are also excluded during siting.

Since wind is a clean and renewable resource, offshore wind turbines do not contribute to GHG emissions or air pollution while generating energy. There are emissions associated with the manufacturing and transportation of turbine components. For this assessment, we did not quantify emissions during the construction of offshore wind farms; these emissions can be addressed with industry-sector solution assessments. Increased deployment of offshore wind turbines contributes to reduced CO₂ emissions when it reduces the need for electricity generation from fossil fuels.

Effectiveness

Based on data provided by the International Energy Agency (IEA), global emissions from electricity generation accounted for an estimated 530 kg CO₂‑eq /MWh (540 kg CO₂‑eq /MWh, 20-yr basis). To convert from MWh to MW, we used the global weighted average capacity factor for offshore wind turbines of 41% (IRENA, 2024c). We estimated offshore wind turbines to reduce 1,900 t CO₂‑eq /MW (1,900 t CO₂‑eq /MW, 20-yr basis) of installed capacity annually (Table 1).

Unit: t CO₂‑eq /MW installed capacity/yr, 100-yr basis

Left Text Column Width

To estimate the effectiveness of offshore wind turbines, we assumed that electricity generated by newly installed offshore wind displaces an equivalent MWh of the global electricity grid mix. Then, the reduction in emissions from additional offshore wind capacity was equal to emissions (per MWh) from the 2023 global electricity grid mix as per the IEA World Energy Balances (IEA, 2024a). We then used the offshore wind capacity factor to convert to annual emissions per MW of installed capacity.

During operation, offshore wind turbines do not emit GHGs, so we assumed zero emissions per MW of installed capacity. However, emissions arise during the manufacturing of components, transportation, installation, maintenance, and decommissioning (Atilgan Turkmen & Germirli Babuna, 2024; Kaldellis & Apostolou, 2017; Mello et al., 2020; Yuan et al., 2023). Life-cycle analyses estimate that lifetime GHG emissions of offshore wind turbines are approximately 25.76 g CO₂‑eq /kWh of electricity generated (Yuan et al., 2023).

In our analysis, we focused solely on emissions produced during electricity generation, so carbon payback time and embodied life-cycle emissions were not included in our estimates of effectiveness or climate impacts.

Cost

We estimated a mean levelized cost of electricity (LCOE) for offshore wind turbines of US$96/MWh based on three industry reports (IEA, 2024b; IRENA, 2024c; Nuclear Energy Agency & IEA, 2020). LCOE is a widely used metric that allows for cost comparison across generation technologies, incorporating installed capital costs, operation and maintenance, project lifespan, and energy output. Between 2010–2023, the global weighted average LCOE for offshore wind fell by 63%, from US$203/MWh to US$75/MWh, reflecting improvements in turbine size, supply chains, and regulatory support (IRENA, 2024c). 

Regional costs vary significantly. Denmark had the lowest LCOE in 2023 at US$48/MWh due to favorable siting conditions and grid cost exemptions. The UK and Germany achieved the largest LCOE reductions since 2010, of 73% and 67%, respectively (IRENA, 2024c). In contrast, recent U.S. estimates exceed US$120/MWh for unsubsidized projects (McCoy et al., 2024), reflecting higher labor costs, permitting challenges, and nascent supply chains. Lazard (2023) reports a broad range of US$72–140/MWh, emphasizing how siting, project size, and technology selection influence cost outcomes.

These values mask substantial variability and project-specific risk factors. LCOEs are highly sensitive to financing terms, interest rates, permitting delays, regional grid integration requirements, and the availability of local supply chains. For context, offshore wind costs are increasingly competitive with fossil fuel–based power generation, which ranges between US$70–176/MWh (IRENA, 2024c). Offshore wind gigawatt-scale potential near load centers makes it a good potential option for decarbonizing coastal grids.

Learning Curve

Offshore wind turbines exhibit a clear learning curve, with costs declining as deployment scales and the technology matures. Learning rates for offshore wind could vary from 7.2–43%, depending on the type of costs considered, study period, technological advancements, and regional conditions. Most of the cost decline is driven by reductions in capital expenditure, particularly from larger turbines, improved manufacturing, streamlined installation, and economies of scale.

According to IRENA (2024c), the global weighted-average installed cost of offshore wind between 2010–2023 reflects a learning rate of 14.2%. Modeling by the U.S. National Renewable Energy Laboratory (NREL) estimates capital cost reductions per doubling of installed capacity at 8.8% for fixed-bottom turbines and 11.5% for floating turbines (Shields et al., 2022). European forecasts suggest that ongoing innovation and learning by doing could reduce offshore wind’s LCOE by up to 25% by 2030 relative to 2020, with learning rates of 6–12% (TNO & BLIX, 2021).

Earlier meta-analyses found offshore wind learning rates of 5–19% between 1985–2001, driven by improved turbine design and installation methods (Rubin et al., 2015). More recent assessments focused on 2010–2016 suggest capital cost learning rates of 10–12% (Beiter et al., 2021). Looking ahead, global experts project cost reductions of 37–49% by 2050 due to continued technological progress (Wiser et al., 2021).

Learning rates also vary by geography. Mature markets like Europe benefit from robust supply chains and permitting frameworks, leading to faster cost declines. On the other hand, emerging markets face higher initial costs and slower learning trajectories. We estimated a 15.8% median global learning rate for offshore wind, implying a 15.8% reduction in LCOE for each doubling of installed capacity (Table 2).

Speed of Action

Speed of action refers to how quickly a climate solution physically affects the atmosphere after it is deployed. This is different from speed of deployment, which is the pace at which solutions are adopted.

At Project Drawdown, we define the speed of action for each climate solution as emergency brake, gradual, or delayed.

Deploy Offshore Wind Turbines is a GRADUAL climate solution. It has a steady, linear impact on the atmosphere. The cumulative effect over time builds as a straight line.

Caveats

One limitation of our approach is the assumption that each additional MWh generated by offshore wind turbines displaces an equivalent MWh of the existing grid mix. This simplification implies that new offshore wind may, at times, displace other renewables such as onshore wind, rather than fossil-based sources. In reality, the extent of avoided emissions varies based on regional grid dynamics, marginal generation sources, and the timing and location of electricity production. This approach could be refined in the future, as emerging evidence suggests that in some cases, wind generation tends to displace a larger share of fossil-fuel output than assumed in average grid-mix methods (e.g., Millstein et al., 2024). While offshore wind avoids many of the land-use constraints associated with onshore wind, it introduces unique challenges that may limit scaling. These include high up-front capital costs, limited port infrastructure, specialized vessels, and supply-chain constraints for large components such as floating platforms and subsea cables. There is also growing competition for ocean space from fisheries, marine conservation zones, and shipping corridors (IEA, 2019).

Like all large-scale infrastructure, offshore wind systems face some risk of early retirement or component failure, which can affect their life-cycle emissions. However, because offshore wind turbines produce zero emissions during operation, any electricity they generate displaces fossil-based power and avoids associated emissions. These benefits are not reversed if a turbine is decommissioned early. Most offshore wind turbines operate for 25–30 years, with newer designs expected to exceed this lifespan (Bills, 2021; IEA, 2019). The bulk of their life-cycle emissions are front-loaded, arising from manufacturing, transportation, and installation. As a result, early retirement reduces the amount of clean electricity generated over the turbine’s lifetime, but it does not erase the emissions already avoided during its operation.

Current Adoption

As of 2023, the global installed capacity for offshore wind energy reached approximately 73,000 MW (Table 3; IRENA, 2024b). Although we used 2023 as our baseline for current adoption, in 2024 an additional 10,000 MW of offshore wind capacity was installed, bringing the global total to over 83,000 MW (GWEC, 2025).

China currently leads in offshore wind deployment, accounting for more than 40 GW, or over half of the global installed capacity. Adoption remains negligible in many countries with several regions – particularly in Africa, Latin America, and parts of Southeast Asia – reporting minimal or no offshore wind installations to date, despite their huge potential (GWEC, 2025). For example, the United States, despite its vast technical potential, had installed only 41 MW by 2023 (IRENA, 2024b).

The global offshore wind market has gained significant momentum in recent years. A record number of new installations occurred in 2021, with continued but slower growth in 2022 and 2023. The most active markets remain concentrated in Asia and Europe, with China, the United Kingdom, Germany, and the Netherlands leading in cumulative capacity. The European Union collectively reached 18.1 GW by 2023 (IRENA, 2024b), driven by favorable policy environments and advanced maritime infrastructure (IRENA, 2024a).

Adoption Trend

Global offshore wind capacity has grown rapidly, expanding from less than 1 GW in 2000 to about 73 GW by 2023 (Figure 2), reflecting technological progress, supportive policies, and accelerating investment.

We calculated global adoption for each year 2013–2023 and took the year-to-year difference. The adoption trend of offshore wind energy from 2013–2023 reveals a rapid and accelerating growth trajectory with significant regional disparities. Globally, installed capacity expanded from 7,200 MW in 2013 to 73,000 MW in 2023, reflecting a 10-fold increase over the decade. The most dramatic acceleration occurred in 2020–2021, when global capacity jumped from 34,000 MW to 54,000 MW. Comparing year-to-year global adoption, the mean global adoption trend was adding approximately 6,000 MW of installed capacity per year (Table 4), but expansion was unevenly distributed geographically.

Regionally, Asia demonstrated the most remarkable growth. This growth was particularly pronounced in 2020–2021, when capacity soared from 9,400 MW to 28,000 MW, largely driven by China’s rapid deployment. Meanwhile, Europe also experienced steady growth, with installed capacity increasing from 8,000 MW in 2014 to 33,000 MW in 2023. In contrast, North America lags behind, with only 41 MW of installed capacity recorded as of 2023, indicating slow current adoption trends. The slow adoption of offshore wind technology in North America may be attributed to various factors, including regulatory and social barriers as well as high interest rates (McCoy et al., 2024). 

Looking ahead, according to forecasts from the World Forum Offshore Wind (WFO, 2024), global offshore wind capacity is anticipated to reach 414 GW by 2032. The GWEC projects more than 350 GW of new offshore wind capacity in 2025–2034, with annual additions surpassing 30 GW by 2030 and 50 GW by 2033, bringing total capacity to about 441 GW by 2034 (GWEC, 2025).

Adoption Ceiling

The adoption ceiling for offshore wind turbines (Table 5) is determined by the technology’s global technical potential, representing the theoretical maximum deployment based on physical resource availability. Offshore wind benefits from vast oceanic areas with higher and more consistent wind speeds than onshore sites. However, its realizable potential is shaped by factors such as water depth, distance to shore, seabed conditions, regional wind patterns, and technological limitations.

Estimates of offshore wind’s technical potential vary widely. A meta-analysis by de La Beaumelle et al. (2023) found values of 4.17–626 petawatt-hours (PWh)/year, with a median of 193 PWh/year. The World Bank’s Energy Sector Management Assistance Program (ESMAP) analysis (2019; n.d.) suggests over 71,000 GW of global offshore wind potential, with more than 70% located in deep waters suitable only for floating turbines. Roughly 25% of this resource lies within low- and middle-income countries, offering major opportunities for clean energy expansion.

Technical potential is typically calculated using wind speed maps, turbine power curves, and water depth data. For example, the ESMAP-IFC 2019 study identified 3.1 terawatts (TW) of potential across eight emerging markets using global wind and ocean depth data (ESMAP, 2019). These figures, however, do not reflect constraints such as economics, regulation, infrastructure, or marine uses that would compete with offshore wind (ESMAP, 2019). Challenges like ecological impact, permitting, and grid integration could significantly reduce practical deployment.

Despite these hurdles, offshore wind’s potential remains vast. For this analysis, we defined the adoption ceiling using installable capacity rather than generation output to avoid forecasting uncertainty. Based on the literature, we estimated an adoption ceiling of 62,000,000 MW. The scaling of floating wind turbines, especially in deep waters, will be critical to unlocking this resource, and will require continued innovation and policy support (Tumse et al., 2024).

left_text_column_width
Achievable Adoption

The IEA’s World Energy Outlook (WEO) 2024 includes several key scenarios that explore different energy futures based on varying levels of policy intervention, technological development, and market dynamics. We define the adoption achievable range for offshore wind turbines based on the Stated Policies Scenario (STEPS) and Announced Pledges Scenario (APS) (IEA, 2024b).

Achievable – Low

The low achievable adoption level is based on STEPS, which captured the current trajectory for increased adoption of offshore wind energy as well as future projections based on existing and announced policies. Under this scenario, offshore wind capacity is projected to increase more than 13-fold from 73,000 MW to 1,000,000 MW by 2050 (Table 6). This corresponds to an average compound annual growth rate (CAGR) of 10.2%.

Achievable – Low 1,000,000
Achievable – High 1,600,000
Adoption Ceiling 62,000,000
Left Text Column Width

Achievable – High

The high achievable adoption level is based on APS, which assumes the same policy framework as STEPS, plus full realization of announced national energy and climate targets – including net-zero commitments supported by stronger clean energy investments. Under this scenario, offshore wind capacity is projected to increase by a magnitude of approximately 22, from 73,000 MW to 1,600,000 MW by 2050 (Table 6). This would require a CAGR of roughly 12.1% over the same period.

Using our adoption ceiling of 62 million MW, the current adoption of offshore wind turbines constitutes approximately 0.1% of its technical potential. The achievable adoption range, as calculated, is 1.6–2.6% of this potential.

left_text_column_width

Using baseline global adoption and effectiveness, we estimated the current total climate impact of offshore wind turbines to be approximately 0.14 Gt CO₂‑eq (0.14 Gt CO₂‑eq , 20-yr basis) of reduced emissions per year (Table 7). We estimated future climate impacts using the emissions from the 2023 baseline electricity grid. Actual emissions reductions could differ depending on how the emissions intensity of electricity generation changes over time. Assuming global policies on offshore wind power – both existing and announced – are backed with adequate implementation provisions, global adoption could reach 1 million MW by 2050. This would result in an increased emissions reduction of approximately 1.9 Gt CO₂‑eq per year. If every nation’s energy and climate targets (including net-zero commitments backed by stronger clean energy investments) are realized, offshore wind adoption could reach 1.6 million MW by 2050. This would lead to an estimated 3.0 Gt CO₂‑eq of reduced emissions per year.

We based the adoption ceiling solely on the technical potential of offshore wind resources, neglecting social and economic constraints. Thus, offshore wind turbines are unlikely to reach an average of 62 million MW of installed capacity in the next 100 years. However, reaching the adoption ceiling would correspond to annual emissions reductions of 120 Gt CO₂‑eq/yr.

Additional Benefits

Income and Work

Wind power has a strong positive impact on the economy. Wind energy projects have been shown to increase total income and employment in high-income and low- and middle-income countries, although the costs of new projects may be higher in emerging markets until the market develops (Adeyeye et al., 2020; GWEC & Global Wind Organization, 2021; World Bank Group, 2021). As the offshore wind sector expands, so will the demand for workers. A report from NREL estimated that U.S. offshore wind projects between 2024–2030 will require an annual average of 15,000–58,000 full-time workers (Stefek et al., 2022). In California, planned and proposed offshore wind farms would add about 5,750 jobs and US$15 billion in wages and further contribute to the local economy by generating tax revenue (E2, 2023). Offshore wind could also strengthen energy security by diversifying the power mix and reducing dependence on imported fuels.

Health

Reduction in air pollution directly translates into health benefits and avoided premature mortality. Simulations of offshore wind projects in China estimate that reductions in air pollution could prevent about 165,000 premature deaths each year (Ren et al., 2025). Proposed offshore wind farms on the Atlantic and Gulf coasts of the United States could prevent about 2,100 premature deaths annually and save money in health benefits from improved air quality (Buonocore et al., 2016; Shawhan et al., 2024). Because these offshore wind projects would lessen demand for natural gas and coal-powered electricity generation, populated communities downwind from power plants along the East Coast of the United States – such as New York City – would experience health benefits from improved air quality (Shawhan et al., 2024). Although the economic benefits of improved health associated with wind power have already increased rapidly from US$2 billion in 2014 to US$16 billion in 2022, these benefits could be maximized by replacing fossil fuel power plants in regions with higher health damages (Qiu et al., 2022). 

Nature Protection

While there are some risks through increased ship traffic and noise and light pollution, offshore wind may provide some benefits to fish and marine life (National Oceanic and Atmospheric Administration, n.d.; Galparsoro et al., 2022; World Economic Forum, 2025). Once constructed, offshore wind farms can serve as an artificial reef, providing new habitats in the submerged portion of the turbine (Degraer et al., 2020). When these habitats are colonized by marine organisms, this increases availability of food such as zooplankton and algae, which can increase the abundance of small fish nearby (Wilhelmsson et al., 2006).

Air Quality

Offshore wind energy reduces air pollutants released from fossil fuels, thereby reducing the emissions associated with burning coal and natural gas. A recent analysis of 32 planned or proposed offshore wind farms along the U.S. Atlantic and Gulf coasts estimated these projects could reduce emissions of nitrogen oxides by 4%, sulfur dioxide by 5%, and PM 2.5 by 6% (Shawhan et al., 2024). Modeling analyses of offshore wind in China estimate these projects could reduce about 3% of air pollution from electricity by lowering emissions from coal-powered electricity generation (Ren et al., 2025).

left_text_column_width
Risks

Implementing offshore wind energy involves several risks. Technically, offshore projects face harsh marine environments that can affect long-term reliability and increase maintenance costs (IRENA, 2024a). These risks can be reduced through advanced materials, corrosion‑resistant designs, predictive maintenance systems, and improved installation practices that extend turbine lifespans and reduce downtime. High capital costs and regulatory uncertainty remain among the most significant barriers, especially in emerging markets where financing, insurance, and investor confidence are limited (ESMAP, 2019). Addressing these challenges often requires stable policy frameworks, innovative financing mechanisms such as Contracts for Difference (CFDs) and blended finance, and public‑private partnerships to de‑risk investments and attract private capital. 

There are also ecological risks associated with offshore wind farms, which can disrupt marine habitats, impact migratory birds and marine mammals, and cause seabed disturbances during installation (Galparsoro et al., 2022). Mitigation strategies such as adaptive siting, seasonal construction limits, and biodiversity offsets are increasingly used to minimize these impacts. Social resistance can arise from local communities due to factors such as visual impact, place attachment, perceived lack of benefits, and competing uses of marine space, such as fisheries and shipping lanes (Gonyo et al., 2021; Haggett, 2011).

Interactions with Other Solutions

Reinforcing

Increased availability of renewable energy from offshore wind turbines helps reduce emissions from the electricity grid as a whole. Reduced emissions from the electricity grid lead to lower downstream emissions for these solutions that rely on electricity use. Deploying offshore wind turbines also supports increased integration of solar photovoltaic technology by diversifying the renewable energy mix and reducing overreliance on solar variability.

left_text_column_width

Electrification of transportation systems will be more beneficial in reducing global emissions if the underlying grid includes a higher proportion of non-emitting power sources. Electric transportation systems can also reduce curtailment of wind energy through controlled-time charging and other load-shifting technologies.

left_text_column_width

Competing

Offshore wind could compete for policy attention and funding with onshore wind turbines, potentially slowing deployment in regions where onshore resources are also viable. Also, increased development and installation of offshore wind turbines could potentially compete with the deployment of those onshore, due to competition for raw materials.

Trade-offs

Offshore wind turbines do not emit GHGs during operation, but they are associated with embodied emissions from manufacturing, transport, and installation (Yuan et al., 2023). The Intergovernmental Panel on Climate Change (IPCC) life-cycle assessment estimates indicate that offshore wind energy produces about 8–35 g CO₂‑eq /kWh, compared to about 400–1,000 g CO₂ --eq/kWh for fossil-based electricity generators (Schlömer et al., 2014).

Increasing steel and concrete demand for turbine construction may cause indirect emissions in the industrial sector. These trade‑offs can be mitigated through circular economy approaches such as recycling and repurposing turbine components to cut material demand and emissions. Despite these trade-offs, the emissions saved over a turbine’s 25- to 30-year lifetime greatly exceed the upfront emissions.

Maps Introduction

Offshore wind energy is most promising in coastal regions with high wind resources and the physical and regulatory capacity to support utility-scale deployment. It is particularly valuable for countries with limited land availability or high coastal population density, offering a scalable and increasingly cost-effective pathway toward decarbonization. Offshore wind’s effectiveness is underpinned by its strong technical fundamentals, especially its relatively high capacity factor.

We estimated global offshore wind technical potential at around 62,000,000 MW. Notably, more than 70% of the technical potential lies in waters deeper than 50 meters. As of 2023, global installed offshore wind capacity had reached 73 GW, a nearly 20-fold increase since 2010. Europe and Asia account for nearly equal shares of current capacity. Europe remains a global leader with around 30 GW, led by the United Kingdom, Germany, Denmark, and Netherlands. 

In Asia, China dominates the offshore wind space, with more than 30 GW installed and annual additions of nearly 17 GW in 2021 alone. Japan has set targets of 10 GW by 2030 and 30–45 GW by 2040, while South Korea aims for 14.3 GW by 2030 (IRENA, 2024a). The United States has vast offshore wind potential, with NREL estimating 1,476 GW for fixed‑bottom and 2,773 GW for floating installations (Lopez et al., 2022). The United States is beginning to scale up offshore wind through policy support from the Inflation Reduction Act, and large-scale projects are now under development along the East Coast. As of May 31, 2024, the country had 174 MW of offshore wind capacity installed (McCoy et al., 2024). While this installed capacity remains modest compared to Europe or China, it represents an initial step in building the domestic industry. Importantly, the U.S. offshore wind project development and operational pipeline exceeds 80,000 MW, highlighting the scale of development expected in the coming decade. Canada, with 9.3 TW of technical potential (7.2 TW of which is suitable for floating wind), has begun leasing processes in Nova Scotia targeting 5 GW by 2030 and integrating offshore wind into its green hydrogen strategy, while Australia’s Victoria state aims for 9 GW by 2040 (IRENA, 2024a).

Several emerging markets represent strong opportunities for future deployment. Brazil has more than 1,200 GW of estimated technical potential and is currently developing a national framework for offshore wind licensing. India plans to reach 37 GW by 2030, with auctions for 7.2 GW already scheduled (IRENA, 2024a). Other countries such as Vietnam and South Africa are beginning to position themselves as offshore wind markets (IRENA, 2024a).

Consensus of effectiveness in reducing GHG emissions: High

The scientific literature on offshore wind turbines reflects high consensus regarding their potential to significantly contribute to reducing GHG emissions and supporting the transition to sustainable energy. Technological advancements, decreasing costs, and increasing efficiency have positioned offshore wind as a key player in achieving global climate targets (Jansen et al., 2020; Letcher, 2023). 

Offshore wind turbines reduce GHG emissions by displacing fossil fuel-based electricity generation, thus avoiding the release of CO₂ and other climate pollutants (Akhtar et al., 2024; Nagababu et al., 2023; Shawhan et al., 2025). The strong and consistent wind speeds found over ocean surfaces make offshore turbines especially efficient, with relatively high-capacity factors and increasingly competitive costs (Akhtar et al., 2021; Bosch et al., 2018; Zhou et al., 2022).

The technical potential of offshore wind refers to the maximum electricity generation achievable using available wind resources, constrained only by physical and technological factors. Scientific reviews highlight the significant technical potential of offshore wind to meet global electricity demand many times over, particularly through expansion in deep waters using floating technologies (de La Beaumelle et al., 2023). The World Bank estimates the global technical potential for fixed and floating offshore wind at approximately 71,000 GW globally using current technology (ESMAP, n.d.). With just 83 GW installed so far (GWEC, 2025), this indicates that offshore wind’s potential remains largely untapped. 

The IPCC also sees offshore wind as a key low-emissions technology for achieving net-zero pathways and can be integrated into energy systems at scale with manageable economic and technical challenges (IPCC, 2023). While there is broad scientific agreement on the potential of offshore wind turbines to significantly reduce GHG emissions, there are also growing concerns, including uncertainties around floating platform scalability, ecological impacts, supply chain readiness, and long-term operations. Most of these issues are captured in the Risks & Trade-Offs section of this document.

The results presented in this document summarize findings from 17 peer reviewed academic papers (including 6 reviews and 11 research articles), 2 books and 11 agency or institutional reports, reflecting current evidence from representative regions around the world. We recognize this limited geographic scope creates bias, and hope this work inspires research and data sharing on this topic in underrepresented regions.

Summary

Onshore wind turbines are land-based machines that harness natural wind to generate electricity. Electricity generation from wind turbines depends on many factors, including natural wind speeds, consistency, and directionality. The Deploy Onshore Wind Turbines solution focuses on utility-scale electricity generation above 1 MW in rated capacity, generally from fields of turbines called wind farms. Small–scale onshore wind and offshore wind energy are discussed as separate solutions.

Deploying onshore wind turbines contributes to reduced CO₂ emissions by increasing the availability of renewable energy sources to meet electricity demand, thereby reducing dependence on fossil fuel–based sources in the overall electricity grid mix.

Description for Social and Search
Deploy Onshore Wind Turbines is a Highly Recommended climate solution. It reduces emissions from electricity generation by expanding production of clean and renewable wind energy.
Overview

An estimated 23% of global GHG emissions on a 100-yr basis comes from electricity generation annually (Clarke et al., 2022), and in 2022 more than 60% of global electricity generation came from fossil fuel–based energy sources (International Energy Agency [IEA], 2024c). Since wind is a clean and renewable resource, onshore wind turbines do not contribute to GHG emissions or air pollution while generating energy. The Deploy Onshore Wind Turbines solution reduces the need for electricity generation from fossil fuels, which reduces emissions of CO₂ as well as of smaller amounts of methane and nitrous oxide. 

An onshore wind turbine has a tower with a rotor mounted at the top, connected to a generator. Wind pressure on the turbine blades rotates the rotor, and the generator converts that motion into electrical power. Power potentially generated is directly proportional to the swept area of the rotor blades and the wind speed cubed. Utility-scale turbines require an annual average wind speed of at least 5.8 m/second (Energy Information Administration [EIA], 2024b). Wind characteristics and technical aspects have a critical impact on electricity generation. Factors include, but are not limited to, wind speed, turbulence, site-specific effects, rotor size, turbine height, generator efficiency, and wind farm layout (Diógenes et al., 2020). Onshore wind farms are often sited where fewer obstacles lead to more consistent wind speeds (Maguire et al., 2024). 

The maximum electrical power a turbine can generate is its installed capacity in MW. Due to changing wind characteristics and operational decisions, onshore wind turbines do not always operate at maximum capacity. The capacity factor of a turbine captures the actual amount of power generated compared with maximum generation if the turbine always operated at its rated capacity. Due to technological improvements over the past decade, global weighted average capacity factors increased from 27% in 2010 to 36% in 2023 and can exceed 50% in some countries (International Renewable Energy Agency [IRENA], 2024).

Utility-scale wind farms are connected to the grid to provide electricity. Electric power output can be converted to energy generated by multiplying capacity by the capacity factor and a specified time interval. For annual generation, we multiplied by one year and used our estimated median global capacity factor (37%). In 2023, onshore wind turbines generated 2,089 TWh of electricity, approximately 7% of global electricity generation (IEA, 2024c).

Onshore wind turbines can be classified according to their orientation. Horizontal-axis turbines need to face their rotors into the wind to generate power, while vertical-axis turbines operate independently of wind direction. Utility-scale onshore wind turbines are mostly horizontal-axis rotors with three blades, but smaller scale turbines (see Deploy Micro Wind Turbines) can have more complex rotor designs for a variety of applications. The International Electrical Commission (IEC) standardizes wind turbine classifications with distinct designs to maximize energy capture for different sites (IEC, 2019). Wind farms also require distribution systems to transport electricity to locations of electricity demand.

Effectiveness

Based on IEA data, global emissions from electricity generation accounted for an estimated 530 kg CO₂‑eq /MWh (540 kg CO₂‑eq /MWh, 20-year basis). To convert from MWh to MW, we used the median global average capacity factor for onshore wind turbines of 37% (IRENA, 2024a). We estimated onshore wind turbines to reduce 1,700 t CO₂‑eq /MW (1,700 t CO₂‑eq /MW, 20-year basis) of installed capacity annually (Table 1).

Left Text Column Width

To estimate the effectiveness of onshore wind turbines, we assumed that electricity generated by new installations displaces an equivalent MWh of the global electricity grid mix. Then, the reduction in emissions from additional onshore wind capacity was equal to emissions (per MWh) from the 2023 global electricity grid mix (IEA, 2024c). We then used the onshore wind capacity factor to convert to annual emissions per MW of installed capacity.

During operation, onshore wind turbines do not emit GHGs. Life-cycle analyses for onshore wind turbines have estimated lifetime GHG emissions as very low, 7–20 g CO₂‑eq per kWh (100-year) of electricity generated (Barthelmie et al., 2021; Wiser et al., 2011). Emissions from manufacturing, transportation, installation, and decommissioning are commonly paid back in less than two years of wind farm operation (Diógenes et al., 2020; Haces-Fernandez et al., 2022; Kaldellis & Zafirakis, 2011). 

Our analysis focused solely on emissions produced during electricity generation; emissions associated with construction and installation of onshore wind are attributed to the Industry, Materials & Waste sector. Thus, we did not include carbon payback time and embodied life-cycle emissions in our estimates of effectiveness, even though this may overestimate climate impacts. We qualitatively discuss life-cycle emissions in Caveats below.

We estimated a mean levelized cost of electricity (LCOE) for onshore wind turbines of US$52/MWh based on 5 industry reports (IEA, 2024; and IEA-OECD Nuclear Energy Agency, 2020; IRENA, 2024a; Wiser et al., 2024). LCOE is commonly used to compare costs across electricity generation technologies because it provides a single metric that combines total installed costs, costs of capital, operating and maintenance costs, the capacity factor, and lifetime of the project (EIA, 2022; Shah & Bazilian, 2020). 

In many global markets, wind power is one of the cheapest ways to generate electricity per MWh (IEA, 2024d); in 2023, newly commissioned onshore wind projects had lower electricity costs than the weighted average LCOE for fossil fuels, which was US$70–176/MWh (IRENA, 2024a). According to IRENA, the global weighted average LCOE for onshore wind turbines declined 91% between 1984–2023 (IRENA, 2024a). Although turbine prices increase with height, revenue from increased power generation available to larger turbines can offset increases in upfront costs, reducing LCOE (Beiter et al., 2021). Additional factors influencing cost-competitiveness of onshore wind include regional energy market fluctuations, social costs of carbon, and subsidies. These factors are not included in our analysis, but some policy levers are discussed in Take Action below.

Learning Curve

Learning rates for onshore wind vary widely due to different underlying assumptions, geographies, and performance metrics. Past learning rate estimates for wind power ranged from –3%, implying that wind power is more expensive over time, to 33% (Beiter et al., 2021). Learning-by-doing rates, based on experience accumulated as capacity increases, ranged from 1–17%, while learning-by-research rates, based on innovation and technological development, ranged from 5–27% (Williams et al., 2017).

More recent LCOE-based learning rate estimates suggest a 10%–20% reduction in LCOE when cumulative global capacity is doubled (Wiser et al., 2021). Since upfront costs are the largest component of LCOE for onshore wind, the reduction in LCOE was driven by a 9–18% decrease in capital expenditures between 2014–2019 due to “turbine price declines, economies of size, technology innovation, and siting choices” (Beiter et al., 2021). Between 2008–2020, onshore wind turbine prices declined by 50% (Wiser et al., 2024). Additionally, installed costs per megawatt decreased with increasing project size, and wind farms above 200 MW had the lowest installed costs (Wiser et al., 2024). Supply chain bottlenecks and higher material costs caused project cost increases between 2020–2022, but in 2023 prices flattened or dropped compared to the previous year (Wiser et al., 2024). Industry experts predicted a 37–49% reduction in wind turbine costs by 2050 (Wiser et al., 2021).

Although learning rates vary from country to country and site to site, we used two high-quality global studies that provided LCOEs for onshore wind to estimate a global learning rate for onshore wind. This resulted in a 28% median global learning rate between 2014–2019 for onshore wind, implying a 28% reduction in LCOE for each doubling of installed capacity during that time period (Table 2).

Speed of Action

Speed of action refers to how quickly a climate solution physically affects the atmosphere after it is deployed. This is different from speed of deployment, which is the pace at which solutions are adopted.

At Project Drawdown, we define the speed of action for each climate solution as emergency brake, gradual, or delayed.

Deploy Onshore Wind Turbines is a GRADUAL climate solution. It has a steady, linear impact on the atmosphere. The cumulative effect over time builds as a straight line.

Caveats

Emissions from fossil fuel–based electricity generation can be reduced with increased deployment of wind power. One limitation of our approach is assuming that each additional MWh of installed capacity displaces one MWh of the existing grid mix. This implies that new onshore wind may, at times, displace other renewables, rather than fossil-based sources. In reality, the extent of avoided emissions varies based on regional grid dynamics, marginal generation sources, and the timing and location of electricity production. This approach could be refined in the future, since wind generation could displace a larger share of fossil-fuel output than assumed in average grid-mix methods (e.g., Millstein et al., 2024). We may overestimate the achievable range of climate impacts because grid-average emissions would decrease over time as more renewables are added to the grid mix. In regions where utility-scale wind farms contribute significantly to the electricity grid, continued expansion also faces socio-ecological challenges due to limited available land with good wind conditions (da Silva and Galvão, 2022). 

Increasing the speed of adoption of onshore wind turbines could lead to issues such as lack of financing, supply chain bottlenecks, land and permit availability, social acceptance, and necessary grid and infrastructure expansion (GWEC, 2024). Globally, bottlenecks in supply chains alongside increased commodity prices for steel and other turbine materials in recent years led to a slowdown in wind power installations compared to solar (Mathis and Saul, 2024). Poor governance and low stakeholder engagement from utilities can also limit future adoption.

Due to the successful adoption of onshore wind in the past, many existing wind farms will reach the end of their average 20- to 25-year project lifetime before 2050 (IEA, 2024b; IRENA, 2024a; Wiser et al., 2024). Global wind energy capacity could decrease as wind farms are decommissioned, which involves dismantling and disposal of turbines and related infrastructure (Agra Neto et al., 2024). However, it is unlikely that a wind farm would be replaced with a nonrenewable energy source (Maguire et al., 2024). Although 85–90% of turbine raw materials can be recycled, including steel and cement, composite materials are still landfilled, with environmental consequences (Barthelmie et al., 2021; GWEC, 2024). Wind farms can also be retrofitted or repowered at the end of their design lifetimes.

GHGs are emitted during construction, installation, operation, decommissioning, and disposal of onshore wind turbines, but full life-cycle emissions are an order of magnitude lower than emissions from fossil fuel–based energy sources (Barthelmie et al., 2021; National Renewable Energy Laboratory [NREL], 2021). Nonoperational emissions are attributed to solutions in the Industry, Materials & Waste sector.

Current Adoption

Current adoption of onshore wind power is well documented by international agencies; we based our estimate on reported installed capacity in 2023 from IRENA, IEA, and the Global Wind Energy Council (GWEC). Globally, onshore wind turbines exceeded 940,000 MW of installed capacity in 2023 (Table 3), based on the median across three global wind energy reports (GWEC, 2024; IEA, 2024d; IRENA, 2024b). Although we used 2023 as our baseline for current adoption, in 2024 an additional 109 GW of onshore wind capacity was installed, bringing the global total to over 1 million MW (GWEC, 2025).

Based on data from IRENA, onshore wind turbines generated electricity in 133 countries (IRENA, 2024b). At the country level, China led the market with more than 400,000 MW, and the lowest current adoption was in Trinidad and Tobago with 0.01 MW. Median country-level adoption was in Mongolia with 160 MW of installed capacity. Countries with less than 1 MW of installed capacity each were excluded from analysis, but their combined installed capacity was 6.4 MW across 16 countries. See Geographic Guidance for more regional details.

Adoption Trend

Based on the IRENA’s 2024 Renewable Energy Statistics, we calculated the global adoption trend by summing adoption across countries for each year between 2013–2023 and taking the year-to-year difference. Comparing year-to-year global adoption, the median global adoption trend was adding 54,000 MW of installed capacity per year (Table 4, Figure 1), but expansion was unevenly distributed geographically.

Between 2010–2023, global cumulative onshore wind installed increased more than fourfold (IRENA, 2024a). Globally new onshore wind deployment declined between 2020–2022, but this trend reversed in 2023 with record global additions of 108,000 MW for a single year (GWEC, 2024; IEA, 2024b). GWEC projected that average annual installations would continue to increase, with 653,000 MW predicted to be added in 2024–2028 (GWEC, 2024).

left_text_column_width
Adoption Ceiling

The availability of wind resources sets the absolute upper limit of the adoption ceiling for onshore wind turbines with additional constraints due to land availability. However, wind resources are not evenly distributed around the world, so there will also be regional adoption ceilings for different countries (Wiser et al., 2011). In the literature, the global technical potential for onshore wind energy is calculated using power curves for turbines, statistical wind speed maps, and simulations (Jacobson & Archer, 2012; Jung, 2024). Land availability constrains the adoption ceiling because siting includes assessments of land cover type and exclusions of protected areas, bodies of water, and urban areas (Angliviel de La Beaumelle et al., 2023). 

At COP28 in 2023, nearly 200 countries pledged to triple renewable energy capacity by 2030 (IEA, 2024a). For onshore wind turbines, tripling capacity would mean accelerating adoption to nearly 270,000 MW installed annually. If that accelerated adoption trend is maintained between 2030–2050, the tripling pledge would result in more than 8.2 million MW of onshore wind turbine installed capacity by 2050. Additionally, the Net Zero Emissions by 2050 scenario in IEA’s World Energy Outlook projected 7.9 million MW of installed capacity for onshore and offshore wind power combined (IEA, 2024d), but we do not include combined wind power estimates in our adoption ceiling. For our analysis, we use the median technical potential to get an adoption ceiling of 12 million MW installed capacity for onshore wind turbines (Table 5).

Achievable Adoption

The IEA’s World Energy Outlook (WEO) 2024 includes several key scenarios that explore different energy futures based on varying levels of policy intervention, technological development, and market dynamics. We define the adoption achievable range for onshore wind turbines based on the Stated Policies Scenario (STEPS) and Announced Pledges Scenario (APS) (IEA, 2024d).

Achievable – Low

The Achievable – Low adoption level is based on STEPS, which captured the current trajectory for increased adoption of onshore wind energy as well as future projections based on existing and announced policies. Under this scenario, onshore wind capacity is projected to increase more than threefold from 940,000 MW to 3,200,000 MW by 2050 (Table 6). 

Achievable – High

The Achievable – High adoption level is based on APS, which assumes the same policy framework as STEPS, plus full realization of announced national energy and climate targets, including net-zero commitments supported by stronger clean energy investments. Under this scenario, onshore wind capacity is projected to increase more than fourfold from 940,000 MW to 4,400,000 MW by 2050 (Table 6).

Current adoption of onshore wind turbines was nearly 8% of our estimated 12 million MW adoption ceiling and the achievable range is between 27% and 37%.

Based on baseline global adoption and effectiveness, we estimate the current total climate impact of onshore wind turbines to be 1.6 Gt CO₂‑eq (1.6 Gt CO₂‑eq , 20-year basis) of reduced emissions per year. We estimated the achievable range of climate impacts using the emissions from the 2023 baseline electricity grid; actual emissions reductions could differ depending on how the emissions intensity of electricity generation changes over time. The IEA Stated Policies Scenario projected that global adoption would reach 3.2 million MW by 2050 (IEA, 2024d), resulting in an increased emissions reduction of 5.4 Gt CO₂‑eq (5.4 Gt CO₂‑eq , 20-year basis) per year. The IEA Announced Pledges Scenario projected 4.4 million MW of installed capacity by 2050 (IEA, 2024d), implying an estimated 7.5 Gt CO₂‑eq (7.5 Gt CO₂‑eq , 20-year basis) of reduced emissions per year (Table 7).

We based the adoption ceiling solely on technical potential and wind resources, neglecting economic constraints, so onshore wind turbines are unlikely to reach 12 million MW of installed capacity in the next 100 years (IEA, 2024d). However, if the adoption ceiling could be reached, annual emissions reductions would be approximately 20 Gt CO₂‑eq (20 Gt CO₂‑eq , 20-year basis).

Additional Benefits

Income and Work

Wind power has a strong positive impact on the economy. Wind energy projects have been shown to increase both total income and employment in high-, low-, and middle-income countries, although the costs of new projects may be higher in emerging markets until the market develops (Adeyeye et al., 2020; GWEC & GWO, 2021; World Bank, 2021). According to the GWEC (2021), the wind power industry has created 1.2 million jobs as of 2021, and could create an additional 3.3 million jobs by 2026. Many of these jobs are in the construction sector. They also include technicians, engineers, manufacturers, analysts, and managers. In the United States, wind energy employed more than 125,000 workers in 2022 (DOE, 2022). Onshore wind could also strengthen energy security by diversifying the power mix and reducing dependence on imported fuels. 

Health

Improvements in air quality offer health benefits from reduced air pollution exposure, including reduced premature mortality. The magnitude and distribution of these benefits depends on the local electricity grid mix and the fuels used to generate electricity (Qiu et al., 2022). In 2022, the air quality health benefits from wind power amounted to US$16 billion at a rate of US$36 per megawatt-hour (Millstein et al., 2024). Health benefits of onshore wind can be greater for racial and ethnic minority groups and low-income populations, who often face higher exposure burdens from fossil-fuel electricity generation; however these benefits also depend on the existing grid and on pollutant transport (Qiu et al., 2022). In the United States, economic benefits of improved health outcomes have already increased from US$2 billion in 2014 to US$16 billion in 2022, but these benefits could be maximized by replacing fossil-fuel power plants in regions with higher health damages (Qiu et al., 2022). 

Nature Protection

While some wind power systems could displace species through habitat loss, careful planning and development could reduce some of these risks and conserve biodiversity (Kati et al., 2021; Tolvanen et al., 2023). Wind-powered electricity generation can benefit the environment by requiring less water than fossil fuel–powered electricity. According to a life-cycle analysis by Meldrum et al. (2013), wind power has the lowest water consumption of all electricity generation methods. 

Air Quality

Wind energy significantly reduces air pollutants released from fossil-fuel energy generation, thereby avoiding the emission of pollutants such as nitrogen oxides, sulfur dioxide, and particulate matter associated with burning coal and natural gas. In the U.S. Midwest, each MWh of wind energy added to the grid can avoid 4.9 pounds of sulfur dioxide and 2.0 pounds of nitrous oxides (Nordman, 2013). A life-cycle analysis of wind power in China found that wind farms could reduce sulfur dioxide,, nitrous oxides, and PM10 emissions by 80.38%, 57.31%, and 30.91%, respectively, compared with emissions from coal-based power plants (Xue et al., 2015). 

left_text_column_width
Risks

Several key risks could prevent growth in installed capacity of onshore wind turbines. Electricity generation from onshore wind turbines inherently fluctuates because wind speeds vary temporally and spatially. Onshore wind turbines face challenges integrating into regional electricity grids (Diógenes et al., 2020; Shafiullah et al., 2013), depending on their location. To reliably meet demand, many grid mixes rely on backup power from coal and natural gas (Haces-Fernandez et al., 2022; Millstein et al., 2024) – although advances in smart grids, storage, and grid flexibility can help reduce reliance on backup fossil-fuel power. Times of high wind generation can create instability (Smith, 2024), leading turbine operators to curtail power output to prevent overloading the electricity grid. Curtailment can also occur due to infrastructure limitations or market conditions (Energy.gov, 2023). However, we found that curtailment was often small: In 2018, less than 2% of wind power was curtailed in the United States and Germany (Zhang et al., 2020). Intermittency in wind energy could also drive increases in electricity costs, but this can be reduced through a variety of generation-side, demand-side, and storage technologies (Ren et al., 2017).

Interactions with Other Solutions

Reinforcing 

Increased availability of renewable energy from onshore wind turbines helps reduce emissions from the electricity grid as a whole. Reduced emissions from the electricity grid lead to lower downstream emissions for solutions that rely on electricity use. Deploying onshore wind turbines also supports increased integration of solar PV by diversifying the renewable energy mix and reducing overreliance on solar variability.

left_text_column_width

Automated and more efficient use of electricity in buildings can shift energy use to times of high renewable generation and reduce electricity demand to help balance intermittency challenges of onshore wind energy.

left_text_column_width

Electrification of transportation systems will be more beneficial in reducing global emissions if the underlying grid includes a higher proportion of non-emitting power sources. Electric transportation systems can also reduce curtailment of wind energy through controlled-time charging and other load-shifting technologies.

Competing

Increased development and installation of onshore wind turbines could compete with deployment of other renewables due to competition for raw materials.

Trade-offs

Siting, transportation, and transmission challenges involve trade-offs between electricity generation requirements, cost, and impacts to people and the environment (Tarfarte and Lehmann, 2023). Construction delays occur due to regulatory and permitting challenges (McKenna et al., 2025; Timilsina et al., 2013). Larger turbines, which provide more power, also exacerbate logistical challenges of construction, transportation, installation, and optimization (Afridi et al., 2024). Construction and siting of new onshore wind farms could threaten land used for agriculture, Indigenous land rights, cultural landscapes, and ecosystems if not carefully assessed during project planning phases, including minimizing visual disturbances and vibrations (Gorayeb et al., 2018; McKenna et al., 2025; Tolvanen et al., 2023). There are emissions associated with land use change (LUC) for new wind farms because sequestered carbon is released as CO₂ when soil is disturbed during construction. The magnitude of LUC emissions depends on the land cover type that the wind farm replaces. LUC emissions caused by constructing on pastureland, cropland, and forests were 6–17% of annual emissions savings from deploying the wind turbines (Albanito et al., 2022; Marashli et al., 2022), and constructing on peatlands could cause emissions greater than the emission savings (Albanito et al., 2022).

Maps Introduction

China, the United States, and Germany lead the market for installed onshore wind capacity, with 60% of global capacity in the United States and China. Installed capacity in China alone was greater than installed capacity across the rest of the world, excluding the United States (IRENA, 2024b). 

Capacity factors vary geographically. In 2023, Brazil had the sixth-highest installed capacity globally (29,000 MW) and reported the highest capacity factors, 54%, while capacity factors in China were only 34%, below the global median capacity factor of 37% (IRENA, 2024). Higher capacity factors lead to better performance and increased electricity output from clean energy sources.

Regions with fossil fuel–dominated grid mixes use onshore wind turbines to diversify electricity sources and cut emissions from electricity generation. Although China led the onshore wind market in 2023, wind energy from both offshore and onshore turbines only accounted for 6% of electricity generation in Asia and the Pacific, while 56% came from coal (IEA, 2022). Germany and Spain had the highest installed capacity in Europe as of 2023 with combined onshore and offshore energy contributing 14% of total electricity generation, the highest percentage of any regional grid (IEA, 2022b). 

While expanding onshore wind in established markets such as Europe is important, targeting regions with little to no electricity generation from renewables could have a larger impact on emissions reductions by providing a clean energy alternative to fossil fuels. It is also critical to ensure that as wind power expands into low- and middle-income countries, the transition to a more renewable electricity grid is done equitably and benefits local communities (Gorayeb et al., 2018).

In 2023, China, the United States, Brazil, Germany, and India cumulatively made up 82% of new global additions to onshore wind capacity (Global Wind Energy Council, 2024). Across all countries with new onshore wind installations in 2023, the median global trend was adding 39 MW of installed capacity per year, but expansion was unevenly distributed around the world. China and India were examples of rapidly expanding markets, with adoption trends of more than 32,000 MW per year and 2,600 MW per year, respectively. Despite a reduction in installations in 2023 compared with 2022, previous installations in the United States contributed to a high 10-year adoption trend of 8,800 MW per year (IRENA 2024). The slowest expanding countries, Denmark and the Netherlands, were adding 130–430 MW of onshore wind turbine capacity per year, most likely due to highly saturated existing markets for wind power. 

There is ample technical potential for onshore wind adoption in Latin America, Africa, the Middle East, and the Pacific, although current installed capacity is relatively low in those regions (IRENA, 2024b; Wiser et al., 2011). The Global Wind Energy Council highlighted Australia, Azerbaijan, Brazil, China, Egypt, India, Japan, Kenya, the Philippines, Saudi Arabia, South Korea, the United States, and Vietnam as markets to watch for growth (GWEC 2024).

Consensus of overall effectiveness of onshore wind turbines: High

Onshore wind energy is inherently renewable and well established as an efficient and effective electricity source. Increasing availability of wind energy reduces the need for fossil fuel–derived energy sources such as coal and gas, leading to lower GHG emissions from the global electricity sector. Through reduced emissions, deploying onshore wind turbines also leads to climate and air quality benefits (Afridi et al., 2024; Millstein et al., 2024). Wind energy is widely adopted around the world, and in 2023 “the country weighted average turbine capacity ranged from 2.5 MW to 5.8 MW” across 133 countries (IRENA, 2024a).

Ongoing innovation is necessary for broader global adoption of onshore wind. Estimates of technical adoption potential depend on site characteristics and socioeconomic conditions (Jung & Schindler 2023; McKenna et al., 2022). According to the Intergovernmental Panel on Climate Change (IPCC), “at low to medium levels of wind electricity penetration (up to 20% of total electricity demand), the integration of wind energy generally poses no insurmountable technical barriers and is economically manageable” (Wiser et al., 2011). Potentially exploitable wind resources are 20–30 times higher than 2017 global electricity demand (Clarke et al., 2022).

The results presented in this document summarize findings from 8 reviews and meta-analyses, 29 original studies, 18 agency reports, and 4 articles reflecting current evidence from 133 countries. We prioritized global data, but some research primarily focuses on trends in the United States, Brazil, China, and Germany. We recognize this limited geographic scope creates bias, and hope this work inspires research and data sharing on this topic in underrepresented regions.

Summary

We define the Deploy Clean Cooking solution as the use of cleaner cooking fuels (liquid petroleum gas, natural gas, electricity, biogas, and ethanol) in place of polluting fuels such as wood, charcoal, dung, kerosene, and coal, and/or the use of efficient cookstove technologies (together called cleaner cooking solutions). Replacing unclean fuel and cookstoves with cleaner approaches can drastically reduce GHG emissions while offering health and biodiversity benefits.

Replacing unclean fuel and cookstoves with cleaner approaches can drastically reduce GHG emissions while offering health and biodiversity benefits.
Overview

Worldwide, cooking is responsible for an estimated 1.7 Gt CO₂‑eq/yr (100-yr basis), (World Health Organization [WHO], 2023), or almost 3% of annual global emissions. Most of these emissions come from burning nonrenewable biomass fuels. Only the CO₂‑eq on a 100-yr basis is reported here due to lack of data on the relative contributions of GHGs. The International Energy Agency (IEA, 2023a) states that 2.3 billion people in 128 countries currently cook with coal, charcoal, kerosene, firewood, agricultural waste, or dung over open fires or inefficient cookstoves because they do not have the ability to regularly cook using cleaner cooking solutions. Even when sustainably harvested, biomass fuel is not climate neutral because it emits methane and black carbon (Smith, 2002).

Clean cooking (Figure 1) reduces GHG emissions through three pathways: 

Improving Efficiency

Traditional biomass or charcoal cookstoves are less than 15% efficient (Khavari et al., 2023), meaning most generated heat is lost to the environment rather than heating the cooking vessel and food. Cleaner fuels and technologies can be many times more efficient, using less energy to prepare meals than traditional fuels and cookstoves (Kashyap et al., 2024). 

Reducing Carbon Intensity

Cleaner fuels have lower carbon intensity, producing significantly fewer GHG emissions per unit of heat generated than conventional fuels. Carbon intensity includes CO₂, methane, and nitrous oxide as well as black carbon. For instance, charcoal cookstoves emit approximately 572 kg CO₂‑eq /GJ of heat delivered for cooking (Cashman et al., 2016). In contrast, liquefied petroleum gas (LPG) and biogas emit about 292 and 11 kg CO₂‑eq /GJ, respectively (Cashman et al., 2016) and, excluding the embodied carbon, stoves that heat with electricity generated from renewable energy sources such as solar, wind, or hydroelectric have zero emissions.

Reducing Deforestation

Cleaner cooking also helps mitigate climate change by reducing deforestation (Clean Cooking Alliance [CCA], 2023) and associated GHG emissions.

Effectiveness

The climate impact of cleaner cooking depends on which fuel and technology is being replaced and what is replacing it. The WHO (2023) categorizes cooking fuels as clean, transitional, or polluting based primarily on health impacts. Clean fuels include solar, electric, biogas, LPG, and alcohols, while kerosene and unprocessed coal are polluting fuels. Biomass cooking technologies may be classified as clean, transitional, or polluting depending on the levels of fine particulate matter and carbon monoxide produced. Switching from traditional cookstoves (polluting) to improved cookstoves (transitional) can reduce emissions 20–40%, while switching to an LPG or electric cookstove can reduce emissions more than 60% (Johnson, 2009). Not including the embodied carbon, switching completely to solar-powered electric cookstoves can reduce emissions 100%.

We estimated the effectiveness of cleaner cooking by calculating the reduction in GHG emissions per household switching to cleaner cooking solutions per year (Table 1). Our analysis of national, regional, and global studies suggested that switching to cleaner fuels and technologies can reduce emissions by 0.83–3.4 t CO₂‑eq /household/yr (100-yr basis), including CO₂, methane, black carbon, and sometimes other GHGs. The large range is due to varying assumptions. For example, the IEA arrived at 3.2 t CO₂‑eq /household/yr (100-yr basis) by assuming that >50% of the households switched to electricity or LPG. In comparison, Bailis et al. (2015) assumed a switch from unclean cookstoves to improved biomass cookstoves, resulting in an emissions reduction of only 0.98 t CO₂‑eq /household/yr (100-yr basis).

While we calculated a median reduction of 2.3 t CO₂‑eq /household switching to cleaner cooking solutions/yr (100-yr basis), the actual reduction per household might be lower because households often stack cleaner cooking fuel with unclean fuel. This could result from multiple socioeconomic factors. For instance, a household may primarily rely on LPG as its main cooking fuel but occasionally turn to firewood or kerosene for specific dishes, price fluctuation, or fuel shortages (Khavari et al., 2023). In rural areas, cleaner fuels and traditional biomass (e.g., wood or dung) are used together to cut costs or due to personal preferences.

left_text_column_width
Cost

People can obtain traditional unclean fuels and traditional woodstoves for little or no cost (Bensch et al., 2021; Kapsalyamova et al., 2021). Our analysis estimated the cost of woodstoves at US$1.50/household and the monetary cost of biomass fuel at US$0.00/household/yr. Over the two-yr lifespan of a woodstove, the net annualized cost is US$0.75/household/yr. While collecting this fuel might be free, it contributes to poverty because households can spend one to three hours daily collecting fuelwood. This can contribute to children, especially girls, missing school (Jameel et al., 2022). 

We estimated the median upfront cost of transitioning from primarily unclean cooking fuels and technology to cleaner cooking to be approximately US$58/household, with stoves lasting 3–10 years. However, the range of annual costs is large because several cleaner cooking technologies have significant variations in price, and cleaner fuel cost is even more variable. Our analysis showed a median annual fuel cost of US$56/household/yr with costs ranging from savings of US$9/household/yr when buying less biomass for more efficient biomass stoves to costs of US$187/household/yr for LPG. We estimated that over a five-year lifespan, cleaner cooking solutions have a net cost of US$64/household/yr.

Our analysis may overestimate operational costs due to a lack of data on biomass and charcoal costs. The IEA (2023a) estimates that an annual investment of US$8 billion is needed to supply cleaner cookstoves, equipment, and infrastructure to support a transition to cleaner cooking. This translates to US$17/household/yr. 

The IEA (2023) assumes improved biomass and charcoal cookstoves are predominantly adopted in rural areas while LPG and electric stoves are adopted in urban regions because, in LMICs, economic and infrastructure challenges can limit access to LPG and electricity in rural areas. If every household were to switch exclusively to modern cooking (e.g., LPG and electricity), the cost would be much higher. The World Bank estimates the cost of implementing these solutions to be US$1.5 trillion between 2020 and 2030 or ~US$150 billion/yr over the next 10 years. This translates into an average cost of US$214/household/yr (World Bank, 2020).

The median cost per unit of climate impact was US$28/t CO₂‑eq (100-yr basis, Table 2), obtained by taking the difference between median cost of cooking with polluting sources and the cost of adopting cleaner fuel, then dividing by the median reduction per household (Table 1). Beyond climate benefits, cleaner cooking offers significant other benefits (discussed below). While the median cost presented here is a reasonable first-order estimate, the actual cost of GHG reduction will depend upon several factors, including the type of stove adopted, stove usage, fuel consumption, and scale of adoption.

Learning Curve

Deploying cleaner cooking is a mature technology, and prices are unlikely to decrease in high-income countries where cleaner cooking fuels and technologies have been completely adopted. Nonetheless, the high cost of cleaner cooking technologies and the fluctuating prices of cleaner cooking fuel have been among the main impediments in the transition of households experiencing poverty away from unclean fuels and technologies. For example, recent price surges in Africa rendered LPG unaffordable for 30 million people (IEA, 2022). Electricity prices have also fluctuated regionally. In Europe and India, prices were higher in 2023 than in 2019 (IEA, 2023b). In contrast, U.S. electricity prices have remained stable over the past five years, while China experienced an 8% decrease.

Speed of Action

Speed of action refers to how quickly a climate solution physically affects the atmosphere after it is deployed. This is different from speed of deployment, which is the pace at which solutions are adopted.

At Project Drawdown, we define the speed of action for each climate solution as emergency brake, gradual, or delayed.

Deploy Clean Cooking is an EMERGENCY BRAKE climate solution. It has the potential to deliver a more rapid impact than gradual and delayed solutions. Because emergency brake solutions can deliver their climate benefits quickly, they can help accelerate our efforts to address dangerous levels of climate change. For this reason, they are a high priority.

Caveats

Households may continue using unclean cooking fuel and technologies alongside cleaner fuels and technologies (referred to as stacking). The data on cleaner cooking are typically measured as the number of households primarily relying on cleaner cooking fuel. This fails to capture the secondary fuel source used in the household. A review from LMICs revealed that stacking can range from low (28%) to as high as 100%, which would mean that every household is simultaneously using cleaner and unclean fuel (Shankar et al., 2020). This can happen due to factors like an increase in the cost of cleaner cooking fuel, cooking preference, unavailability of cleaner fuel, and unfamiliarity with cleaner cooking technologies. Stacking is challenging to avoid, and there is a growing realization from cleaner cooking practitioners of the need for cleaner approaches, even when multiple stoves are used. For example, electric stoves can be supplemented with LPG or ethanol stoves.

Permanence

There are significant permanence challenges associated with cleaner cooking. Households switch back from cleaner cooking fuels and technologies to unclean fuels and technologies (Jewitt et al., 2020). 

Finance

Finance is vital to supercharge adoption of cleaner cooking. Investment in the cleaner cooking sector remains significantly below the scale of the global challenge, with current funding at approximately US$130 million. This is many times lower than the amount needed each year to expand adoption of cleaner cooking solutions for the 2.4 billion people who still rely on polluting fuels and technologies (CCA 2023). At the current business-as-usual adoption rate, limited by severe underfunding, more than 80% of the population in sub-Saharan Africa will continue to rely on unclean fuels and technologies in 2030 (Stoner et al., 2021)

Climate funding, developmental finance, and subsidies have made some progress in increasing adoption of cleaner cooking. For instance, the World Bank invested more than US$562 million between 2015 and 2020, enabling 43 million people across 30 countries to adopt cleaner cooking solutions (ESMAP, 2023; World Bank, 2023). However, the emissions reductions these programs achieve can be overestimated. A recent analysis (Gill-Wiehl et al., 2024) found that 26.7 million clean cooking offset credits in reality only amounted to about 2.9 million credits. This discrepancy underscores the urgent need for updated methodologies and standards to accurately estimate emissions reductions and the cost of reduction per t CO₂‑eq (100-yr basis). 

left_text_column_width
Current Adoption

The WHO (2025) estimated that 74% of the global population in 2022 used cleaner cooking fuels and technologies. This translates to 1.2 billion households using cleaner cooking (Table 2) and 420 million households that have yet to switch to clean cooking solutions (Table 6). The adoption of cleaner cooking is not evenly spread across the world. On the higher end of the spectrum are the Americas and Europe, where, on average, more than 93% of people primarily rely on cleaner cooking fuels and technologies (WHO, 2025). On the lower end of the spectrum are sub-Saharan countries such as Madagascar, Mali and Uganda, where primary reliance on cleaner cooking fuel and technologies is <5%. While current adoption represents households that enjoy cleaner cooking today, our analysis for achievable adoption and adoption ceiling focuses on quantifying households that currently use traditional cooking methods and can switch to cleaner cooking. 

To calculate climate impact of this solution, we defined the adoption unit as households switching to clean cooking after 2022. For this reason, current adoption in Table 6 and the solution summaries is not determined.

Adoption Trend

Global adoption of cleaner cooking fuel and technologies as the primary source of cooking increased from 61% of the population in 2013 to 74% in 2023 (WHO, 2025). This translates to roughly 21 million households adopting cleaner cooking technologies/yr (Table 3). This uptake, however, is not evenly distributed (see Maps section above).

Large-scale adoption across China, India, and Indonesia has driven the recent increase. Between 2011 and 2021, use of cleaner fuels and technologies as the primary means of cooking rose from 61% to 83% of the population in China. In India, adoption expanded from 38% to 71%, and in Indonesia, it increased from 47% to 87% (WHO, 2024a). In contrast, primary reliance on cleaner cooking in sub-Saharan Africa only increased from 12% in 2010 to 16% in 2020 (Stoner et al., 2021). 

Based on the existing policies, population growth, and investments, more than 75% of the sub-Saharan African population will use unclean cooking fuels and technologies in 2030 (Stoner et al., 2021). In Central and Southern Asia, about 25% of the population will use unclean cooking fuels and technologies by 2030 (Stoner et al., 2021).

Adoption Ceiling

The World Bank (2020) estimated that universal adoption of modern energy cooking services by 2030 is possible with an annual investment of US$148–156 billion, with 26% of the investment coming from governments and development partners, 7% from private investment, and 67% from households. Universal adoption and use of cleaner fuels and technologies is possible with an investment of US$8–10 billion/yr (IEA, 2023a; World Bank, 2020). We therefore set the adoption ceiling at 100% of households adopting and using cleaner cooking solutions, which entails 420 million households switching from unclean solutions (Table 4).

Achievable Adoption

Universal adoption and use of cleaner cooking solutions is achievable before 2050 (Table 5). This is because if the current adoption trend continues, all households that currently use unclean cooking fuels and technologies will have switched to using cleaner versions by 2043. 

China, India, and Indonesia have shown that it is possible to rapidly expand adoption with the right set of policies and investments. In Indonesia, for example, use of cleaner cooking solutions increased from 9% of the population to 89% between 2002 and 2012 (WHO, 2025).

Cooking from all fuel types is responsible for approximately 1.7 Gt CO₂‑eq (100-yr basis) emissions every year (WHO, 2023), on par with global emissions from the aviation industry (Bergero et al., 2023). Unclean cooking fuels and technologies are also the largest source of black carbon (Climate & Clean Air Coalition, 2024), a short-lived climate pollutant with a GWP several hundred times higher than CO₂ that contributes to millions of premature deaths yearly (Garland et al., 2017). 

The actual reduction in climate impact will depend upon the mix of cleaner fuel and technologies that replace unclean fuel. The IEA (2023a) estimates that if the cleanest cooking fuels and technologies (e.g., electric and LPG) are adopted, emissions could be reduced by 1.5 Gt CO₂‑eq/yr (100-yr basis) by 2030. In contrast, a greater reliance on improved cookstoves as cleaner cooking solutions will result in lower emissions reductions. The WHO (2023) estimates that much of the shift by 2030 will involve using improved biomass and charcoal cookstoves, especially in rural areas, reducing emissions 0.6 Gt CO₂‑eq/yr (100-yr basis) by 2030 and ~1.6 CO₂‑eq/yr (100-yr basis) by 2050, closely matching the IEA estimate.

According to our analysis, deploying cleaner cooking can reduce emissions by 0.98 Gt CO₂‑eq/yr (100-yr basis) between now and 2050 (Table 6). Our emissions reduction estimates are lower than those of the IEA because we do not assume that the shift to cleaner cooking will be dominated by LPG and renewables.

Additional Benefits

Income and Work

Simkovich et al. (2019) found that time gained by switching to cleaner fuel can increase daily income by 3.8–4.7%. Their analysis excludes the expenses related to fuel, as well as the costs associated with delivery or transportation for refilling cleaner fuel. Mazorra et al. (2020) reported that if 50% of the time saved from not gathering firewood were redirected to income-generating activities, it could lead to an estimated annual income increase of approximately US$125 (2023 dollars) in the Gambia, US$113 in Guinea-Bissau, and US$200 in Senegal. Health and Air Quality

Unclean cooking fuels and technologies produce household air pollution (HAP), with smoke and fine particulates sometimes reaching levels up to 100 times acceptable limits, particularly in poorly ventilated spaces (WHO, 2024b). HAP is linked to numerous health issues, such as stroke, ischemic heart disease, chronic obstructive pulmonary disease, lung cancer, and poor birth outcomes (Jameel et al., 2022). It accounts for more than 3.2 million early deaths annually (WHO, 2024b). In 2019, it accounted for over 4% of all the deaths globally (Bennitt et al., 2021). The World Bank (2020) estimated that the negative health impact of unclean cooking fuels and technologies is valued at US$1.4 trillion/yr. Globally, switching to cleaner fuels and technologies could prevent 21 million premature deaths from 2000–2100 (Lacey et al., 2017). A recent study offered empirical evidence of potential cardiovascular benefits stemming from household cleaner energy policies (Lee et al., 2024).

Equality

Unclean cooking disproportionately impacts women and children who are traditionally responsible for collecting fuelwood or biomass. Typically, they spend an hour every day collecting solid fuel; however, in some countries (e.g., Senegal, Niger, and Cameroon), daily average collection time can exceed three hours (Jameel et al., 2022). Time-saving cooking fuels are associated with more education in women and children (Biswas & Das, 2022; Choudhuri & Desai, 2021) and can additionally promote gender equity through economic empowerment by allowing women to pursue additional employment opportunities (CCA, 2023). In conflict zones, adoption of cleaner fuels and technologies has been shown to reduce gender-based violence (Jameel et al., 2022). Finally, cleaner cooking fuels can improve health equity as women are disproportionately exposed to indoor air pollution generated from cooking (Fullerton et al., 2008; Po et al., 2011). 

Nature Protection

The unsustainable harvest of wood for cooking fuel has led to deforestation and biodiversity loss in regions such as South Asia and sub-Saharan Africa (CCA, 2022). East African nations, including Eritrea, Ethiopia, Kenya, and Uganda, are particularly affected by the rapid depletion of sustainable wood fuel resources. In the Democratic Republic of the Congo, 84% of harvested wood is charcoal or firewood (World Bank, 2018). Switching to cleaner cooking fuels and technologies can reduce deforestation and protect biodiversity (Anenberg et al., 2013; CCA, 2022; Dagnachew et al., 2018).

left_text_column_width
Risks

The expensive nature of cleaner cooking presents a significant barrier to adoption. Households that have recently transitioned to cleaner cooking face a high risk of defaulting back to unclean fuels and technologies. For example, among the households that received free LPG connection as a part of the Pradhan Mantri Ujjwala Yojana in India, low-income households reverted to unclean fuels and technologies during extensive periods of refill gaps (Cabiyo et al., 2020). In total, 9 million recipients could not refill their LPG cylinders even once in 2021–22 due to high LPG costs and other factors (Down to Earth, 2022).

Beyond the cost, there is an adjustment period for the households adopting the cleaner cooking solution, which includes familiarizing themselves with the technology and fostering cultural and behavioral changes, including overcoming biases and adopting new habits.

Trade-offs

Switching to electric cooking will meaningfully reduce GHG emissions only if the grid is powered by clean energy. A life-cycle assessment of cooking fuels in India and China (Cashman et al., 2016) showed that unclean cooking fuels such as crop residue and cow dung had a lower carbon footprint than electricity because in these countries >80% of the electricity was produced by coal and natural gas. 

LPG has been the leading cleaner fuel source replacing unclean cooking fuel globally (IEA, 2023a). The IEA (2023a) estimated that 33% of households transitioning to cleaner cooking fuels and technologies will do so using LPG to transition. Because LPG is a fossil fuel, increased reliance can hinder or slow the transition from fossil fuels.

Maps Introduction

The Deploy Clean Cooking solution applies to geographies where low-cost, inefficient, and polluting cooking methods are common. Sub-Saharan Africa is the overwhelming target, with only 23% of the population relying on clean cooking technologies (WHO, 2025). 

There are significant correlations between the lack of clean cooking solutions and levels of extreme poverty (World Bank, 2024). The financial cost of clean fuel and cookstoves is a significant barrier to adoption (WHO, 2023).  

Some of the key benefits of deploying clean cooking will vary based on geography and landscape. For instance, freeing up time spent collecting firewood will be more notable in areas with less dense forest, since people in such locations would have to travel farther to harvest wood (Khavari et al., 2023).

Barriers to the adoption of clean cooking can also vary with geography. Examples noted by Khavari et al. (2023) include robustness of supply chains, which can be influenced by population density and road networks.

Evidence Base

There is a strong consensus on the effectiveness of cleaner cooking as a climate solution. Research over the past two decades (e.g., Anenberg et al., 2013; Mazorra et al., 2020; Rosenthal et al., 2018) has supported the contention that replacing solid fuel cooking with cleaner fuel reduces GHG emissions. 

There is high agreement and robust evidence that switching cooking from unclean fuels and technologies to cleaner alternatives such as burning LPG or electric stoves offers health, air quality, and climate change benefits (Intergovernmental Panel on Climate Change [IPCC], 2022).

The IPCC (2022) identified unclean fuels such as biomass as a major source of short-lived climate pollutants (e.g., black carbon, organic carbon, carbon monoxide, and methane) and switching to cleaner fuels and technologies can reduce the emission of short-lived climate pollutants.

Regional and country-level analyses provide additional evidence of the efficacy of cleaner cooking solutions. Khavari et al. (2023) reported that in sub-Saharan Africa, replacing unclean solid fuels with cleaner cooking could reduce GHG emissions by 0.5 Gt CO₂‑eq/yr (100-yr basis). Life cycle assessments comparing different cooking fuels and technologies (Afrane & Ntiamoah, 2011; Afrane & Ntiamoah, 2012; Lansche & Müller, 2017; Singh et al., 2014) also have shown that cleaner cooking fuels and technologies emit less GHG per unit of energy delivered than unclean fuels.

The IEA estimated that switching completely to clean cooking fuels and technologies by 2030 would result in a net reduction of 1.5 Gt CO₂‑eq/yr (100-yr basis) by 2030 (IEA, 2023a). 

The results presented in this document summarize findings from five reviews and meta-analyses and 23 original studies and reports reflecting current evidence from 13 countries, primarily in sub-Saharan Africa. We recognize this limited geographic scope creates bias, and hope this work inspires research and data sharing on this topic in underrepresented regions.
