The global renewable energy sector continues its unprecedented expansion trajectory in 2025, building upon record-breaking growth achieved in 2024. According to data from the International Renewable Energy Agency (IRENA), renewable power capacity reached 4,448 GW by the end of 2024, representing a 15.1% increase from 2023 and significantly outpacing the 10.4% compound annual growth rate observed over the preceding five years.
Solar photovoltaic technology maintains its position as the primary driver of renewable energy expansion, accounting for the largest share of global renewable capacity at 1,865 GW. Wind energy follows as the second-largest contributor with 1,133 GW of installed capacity. Together, these two variable renewable sources comprise 67.5% of total renewable capacity and an remarkable 97.5% of all net renewable additions in 2024.
Looking ahead, the International Energy Agency (IEA) forecasts that renewable power capacity will increase by nearly 4,600 GW between 2025 and 2030, effectively doubling the deployment achieved during the previous five-year period. However, this outlook represents a 5% downward revision from the 2024 forecast, reflecting policy uncertainties, regulatory changes, and evolving market conditions that have emerged since October 2024.
Solar energy continues to cement its position as the dominant force in renewable energy expansion. According to the Solar Energy Industries Association (SEIA), the U.S. solar industry installed 43.2 GW of capacity in 2025, marking the fifth consecutive year that solar has led all new electricity-generating capacity additions. Solar photovoltaic systems accounted for 54% of all new U.S. electricity-generating capacity, with solar and storage combined representing 85% of new capacity additions through the first three quarters of 2025.
The global pipeline for planned wind and utility-scale solar projects reached 4.9 terawatts in 2025, representing an 11% increase from 4.4 TW in 2024, according to Global Energy Monitor. This growth marks significant progress toward the global target of tripling renewable energy capacity, as wind and solar are expected to comprise 94% of renewable additions needed to achieve this goal.

Geographic distribution of solar installations reveals shifting market dynamics. Texas maintained its position as the fastest-growing solar market, adding approximately 11 GW of new capacity in 2025, roughly matching the state's total from the previous two years combined. California ranked second with 4.7 GW of additions, while Indiana emerged as a rising market, jumping from 10th place in 2024 to 3rd place nationally with 3 GW installed.
Notably, 11 states set new annual installation records in 2025, and 12 states added over 1 GW of new solar capacity. The report found that over two-thirds of all solar capacity installed in 2025 was built in states that supported the 2024 presidential election's winning candidate, demonstrating the bipartisan appeal of solar economics.
The utility-scale segment experienced a 16% decline compared to 2024, with 34.7 GW installed. This decrease was attributed to changes in tax credit deadlines that led developers to delay commercial operation dates and focus on safe-harboring their pipeline. Utility-scale pricing increased by 11% for fixed-tilt racking installations and 14% for single-axis trackers, driven by increases in structural and electrical component costs.
Commercial solar demonstrated resilience with 6% growth, adding 2.3 GWdc of new capacity. California dominated this segment, accounting for 39% of national installations and posting 28% year-over-year growth. The commercial segment grew 11% quarter-over-quarter in Q4 2025, driven largely by NEM 2.0 projects coming online in California.
U.S. solar manufacturing capacity expanded significantly in 2025, with module manufacturing growing more than 50% to reach 65.5 GW of capacity online, up from 42.5 GW at the end of 2024. Cell production capacity continued to expand, and wafer capacity came online for the first time since 2016, marking a significant milestone in domestic supply chain development.
The global wind power sector recorded exceptional growth in the first half of 2025, with installations rising by 64% compared to the same period in 2024. According to the World Wind Energy Association (WWEA), a total of 72.2 GW of new capacity was added between January and June 2025, compared to 44.1 GW in the first half of 2024.
Over the twelve months from July 2024 to June 2025, the sector added 148 GW of capacity, compared with 125 GW during the preceding twelve-month period. By the end of June 2025, total installed wind power capacity reached 1,245 GW (1.25 terawatts), representing a 13.5% annual growth rate. Wind energy now provides approximately 12% of global electricity demand.

China continues to dominate global wind installations, contributing more than two-thirds of total capacity added. In the first half of 2025 alone, China added 51.4 GW of wind capacity, more than double the previous year's first-half performance. The Asia-Pacific region leads globally, with China's installations comprising approximately 70% of the global total.
Offshore wind represents a critical growth frontier for the wind industry, though it faces near-term challenges. The IEA projects offshore wind capacity expansion to reach 140 GW over the 2025-2030 forecast period, more than doubling the growth of the previous five-year period. The annual offshore wind market is expected to expand from 9.2 GW in 2024 to over 37 GW by 2030.
China is positioned to account for almost 50% of this offshore wind increase, while Europe's annual market is expected to approach 14.6 GW by 2030. However, policy changes in the United States, macroeconomic pressures, and supply chain challenges have raised costs and undermined project bankability in several European markets and Japan, resulting in undersubscribed auctions and project cancellations.
These challenges have led the IEA to revise its global offshore wind capacity forecast downward by 27% from the previous year. Offshore wind auction volumes plummeted to just 2.5 GW in the first half of 2025, reflecting the sector's current difficulties despite its long-term potential.
Onshore wind has demonstrated remarkable momentum in 2025. Awarded auction volumes in the first half of 2025 showed a significant shift in technology shares, with onshore wind accounting for approximately 33% of global auction volumes, the highest awarded capacity in any six-month period before 2024. For the first time, onshore wind auction volumes were similar to awarded solar PV capacity.
This surge results mainly from permitting condition improvements that addressed years of undersubscribed auctions, particularly in Germany, which awarded nearly 11 GW of new onshore wind capacity in tenders, representing a remarkable 70% increase year-on-year. The IEA expects cumulative onshore wind capacity additions to increase 45% over 2025-2030, reaching 732 GW.
Emerging markets are increasingly contributing to global wind growth. Brazil has consolidated its position as the fifth-largest market worldwide, while rising stars such as Uzbekistan, Egypt, and Saudi Arabia demonstrated strong performances in 2024, representing the next wave of wind energy growth across an increasingly diverse geographic landscape.
The Global Wind Energy Council (GWEC) expects new installations to surpass previous records and reach 139 GW in 2025, with 981 GW of new capacity likely to be added through 2030 under current policies. This equates to 164 GW of new installations each year until 2030, representing a projected compound annual growth rate of 8.8% for the 2025-2030 period.
The renewable energy sector in 2025 presents a landscape of continued robust growth tempered by emerging challenges. While solar and wind technologies maintain their trajectory as the dominant sources of new electricity capacity globally, policy uncertainties, supply chain constraints, and macroeconomic pressures are creating headwinds that have led international agencies to moderate their forecasts.
Several key strategic insights emerge from this analysis:
Technology Leadership: Solar PV has firmly established itself as the leading renewable technology, driven by declining costs, improving efficiency, and broad social acceptance. The technology accounts for nearly 80% of projected renewable electricity capacity expansion through 2030. However, the IEA's downward revision of solar forecasts by over 70% of the total 248 GW reduction reflects real-world deployment challenges.
Geographic Shifts: China continues to dominate both solar and wind installations, accounting for the majority of global capacity additions. The concentration of manufacturing capacity in China, combined with its aggressive domestic deployment, positions the country as the central player in global renewable energy markets. Meanwhile, the G7's wind and utility-scale solar pipeline has remained mostly unchanged at around 520 GW since 2023, highlighting a misalignment between current pipelines and required progress to meet climate targets.
Offshore Wind Challenges: While offshore wind holds tremendous long-term potential, the sector faces significant near-term headwinds. The 27% downward revision in offshore wind forecasts reflects project cancellations, undersubscribed auctions, and rising costs in key markets. Addressing these challenges will require coordinated policy support, supply chain investments, and regulatory clarity.
Manufacturing Resilience: The expansion of domestic solar manufacturing capacity in the United States and other markets represents a positive development for supply chain resilience. However, actual production remains considerably below domestic demand, indicating the need for continued investment in manufacturing scale-up.
Looking ahead, the renewable energy sector remains positioned for substantial growth, with the IEA projecting nearly 4,600 GW of additions between 2025 and 2030. Achieving this potential will require addressing the policy, regulatory, and market barriers that have emerged, while maintaining the cost competitiveness and technological innovation that have driven renewable energy's success to date.
The industry's ability to navigate these challenges will determine whether the world can achieve the tripling of renewable capacity by 2030 that scientists and policymakers have identified as essential for meeting global climate goals. With wind and solar comprising 94% of the renewable additions needed, the success of these two technologies will largely define the pace of global energy transition.
