Technological innovation continues to drive down costs and improve efficiency. Module prices continued to decline through 2024 and into 2025, despite supply chain pressures, stimulating demand across all market segments. Chinese manufacturer JinkoSolar set a world record with its TOPCon modules, achieving 25.58% efficiency—demonstrating the continued potential for performance improvements.
Emerging applications are expanding the addressable market for solar. Agrivoltaic systems, which combine solar generation with agricultural production, are gaining traction as farmers seek dual revenue streams. Floating photovoltaics (floatovoltaics) are being deployed on reservoirs and canals, providing clean energy while reducing water evaporation. Solar carports are increasingly popular for commercial installations, generating electricity while providing vehicle protection.
By June 2025, China's wind and solar capacity reached 1.67 TW, surpassing thermal power capacity for the first time—a historic milestone in the global energy transition. To stabilize supply from this variable generation, China targets 240 million kilowatts of energy storage by 2030.
The global wind power sector recorded strong 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, a total of 72.2 GW of new capacity was added between January and June 2025, up from 44.1 GW in the first half of 2024.
By the end of June 2025, total installed wind power capacity reached 1,245 GW (1.25 TW), representing a 13.5% annual growth rate. Wind energy now provides approximately 12% of global electricity demand. The full-year 2025 outlook anticipates approximately 150 GW of new installations, with projected total capacity exceeding 1,320 GW by year-end.
Onshore wind auction volumes showed significant momentum in 2025. In the first half of the year, onshore wind accounted for approximately 33% of global auction volumes—the highest awarded capacity in any six-month period before 2024, and for the first time similar to awarded solar PV capacity. Germany led this surge, awarding nearly 11 GW of new onshore wind capacity in tenders, representing a remarkable 70% year-on-year increase.
Offshore wind represents both significant opportunity and considerable challenge for the industry. Global offshore wind capacity reached 83 GW by the end of 2024, with an additional 48 GW under construction as of May 2025, positioning the sector for accelerated growth through the decade.
The International Energy Agency 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, with China accounting for almost 50% of this increase. In Europe, the annual market is expected to approach 14.6 GW by 2030.
However, the offshore sector faces significant headwinds. 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. The IEA revised its global offshore wind capacity forecast downward by 27% from the previous year.

The global renewable energy landscape is characterized by significant regional disparities in deployment, policy support, and market maturity. Understanding these dynamics is essential for stakeholders seeking to navigate the evolving competitive landscape.
China continues to dominate global renewable energy deployment, accounting for approximately 70% of global wind installations and nearly 60% of solar PV additions. By mid-2025, China's wind and solar capacity reached 1.67 TW, surpassing thermal power for the first time—a historic milestone in the global energy transition.
China's wind and solar pipeline grew from 1.2 TW to 1.5 TW in 2025, demonstrating continued commitment to capacity expansion. The country's manufacturing scale has driven down costs globally, with Chinese module production capacity exceeding 40 GW per year. However, China's shift from fixed tariffs to competitive auctions is impacting project economics and lowering growth expectations relative to previous years.
The US renewable energy market faces significant policy headwinds in 2025. The IEA revised its US renewable capacity forecast down by approximately 50% for the 2025-2030 period following policy changes including the earlier phase-out of federal tax credits, new import restrictions, suspension of new offshore wind leasing, and restrictions on permitting wind and solar projects on federal land.
Wind energy specifically saw a 60% downward revision, representing 57 GW of capacity—both onshore and offshore—that is now unlikely to be built during the forecast period. Despite these challenges, the US added 50.3 GW of renewable capacity in 2025, marking a record year for deployment even as the outlook dims.
Europe's wind and utility-scale solar pipeline remained relatively stable at around 520 GW since 2023, despite IRENA's calls for G7 countries to more than double their annual renewable energy capacity additions through 2030. Germany's remarkable 70% year-on-year increase in onshore wind tenders represents a bright spot, driven by permitting improvements and energy security concerns.
Offshore wind in Europe faces challenges from higher costs and supply chain constraints, with several projects experiencing delays or cancellations. However, the annual market is still expected to approach 14.6 GW by 2030, supported by strong policy frameworks in countries like the UK, Netherlands, and Denmark.
Countries outside the G7 and China achieved significant growth, with their wind and solar pipeline expanding from 2.7 TW to 2.9 TW in 2025. Rising stars such as Uzbekistan, Egypt, and Saudi Arabia demonstrated strong performances in 2024, representing the next wave of renewable energy growth.
The Asia-Pacific region continues to lead outside China, with Japan, South Korea, the Philippines, and Australia progressing their wind energy markets. Africa and the Middle East had a record year, doubling onshore wind additions in 2024. Brazil's recently passed legislation on offshore wind, green hydrogen, and industrialization is creating new opportunities in a country already considered a wind energy leader.
Despite the impressive growth trajectory, the renewable energy sector faces several significant challenges that could impede progress toward 2030 targets.
Policy instability represents the most significant near-term risk. In the United States, 87 new trade and tariff policies announced in 2025 created unpredictability for companies with exposure to cleantech supply chains. The abrupt phase-out of many federal tax credits in late 2025 forced businesses to adjust development plans, while federal permitting revocations and restrictions added delays to already lengthy approval timelines.
Supply chain challenges continue to affect project economics. While module prices have declined, other components—including wind turbines, inverters, and battery storage systems—face cost pressures from inflation, raw material volatility, and logistics constraints. Offshore wind has been particularly affected, with several developers reducing their 2030 deployment targets due to higher costs and supply chain challenges.
The rapid growth of variable renewable generation is straining electricity grids worldwide. Grid connection wait times remain lengthy in many markets, and the need for storage and flexibility solutions is becoming increasingly urgent. China's target of 240 million kilowatts of energy storage by 2030 illustrates the scale of investment required to support high renewable penetration.
Perhaps the most significant challenge is the widening gap between current growth trajectories and the 2030 tripling target. IRENA analysis indicates that if the same annual growth rate continues, the world will only reach 10.3 TW of renewable capacity by 2030—missing the 11 TW target by 0.9 TW. Achieving the target would require renewable capacity to expand at 16.6% annually through 2030, significantly faster than current rates.
The renewable energy sector in 2025 stands at a pivotal moment. Record-breaking deployment, with solar and wind now outpacing global electricity demand growth, demonstrates the sector's maturation and competitiveness. Investment flows have reached new heights, and technological advances continue to improve performance while reducing costs.
However, significant challenges temper this optimistic outlook. Policy uncertainty, particularly in major markets like the United States, is disrupting project pipelines and investor confidence. Supply chain constraints and rising costs are affecting project bankability, particularly in offshore wind. Most critically, the gap between current growth rates and the 2030 tripling target is widening, requiring accelerated deployment to meet global climate commitments.
For Developers: Focus on markets with stable policy frameworks and strong grid infrastructure. Diversify technology portfolios to balance solar and wind exposure. Invest in storage and flexibility solutions to enhance project value.
For Investors: Capital is increasingly flowing toward markets with stronger project returns and policy certainty. Europe and select emerging markets offer attractive opportunities as US policy headwinds persist.
For Policymakers: Streamlined permitting, grid infrastructure investment, and stable long-term policy frameworks are essential to accelerate deployment and close the gap to 2030 targets.
Looking ahead, the renewable energy sector's fundamentals remain strong. The technologies are proven, costs are competitive, and demand for clean electricity is growing rapidly, driven by electrification, data center expansion, and corporate sustainability commitments. The question is not whether renewable energy will dominate the future power system, but whether deployment can accelerate fast enough to meet climate imperatives.
The path to 2030 requires a sprint, not a steady jog. With the right policy frameworks, financing mechanisms, and grid infrastructure investments, the industry can rise to meet the tripling challenge. The stakes could not be higher—for the energy sector, for the global economy, and for the climate.
