Global Market Outlook and Strategic Insights
The global renewable energy sector reached a historic milestone in 2025, with solar and wind technologies now expanding fast enough to meet all new electricity demand growth worldwide. This report examines the key trends, market dynamics, and strategic implications for stakeholders across the renewable energy value chain.
The renewable energy landscape in 2025 is characterized by a paradox: unprecedented growth in absolute terms alongside increasing policy uncertainty and regional divergence. While China continues to dominate capacity additions, accounting for nearly 60% of global solar installations, emerging markets are showing accelerated growth as costs decline and policy frameworks mature.
Looking ahead, the industry must navigate a complex environment of rising interest rates, supply chain constraints, and evolving policy frameworks. Success will require strategic focus on grid integration, energy storage, and emerging market expansion.
The renewable energy sector has entered a new phase of maturity in 2025, characterized by scale, complexity, and increasing integration with broader energy system transformation. Global renewable power capacity stood at approximately 4,448 GW at the end of 2024, with solar accounting for 1,865 GW, wind for 1,133 GW, and hydropower for 1,283 GW.
The year 2025 marked a watershed moment as solar and wind together supplied 17.6% of global electricity in the first three quarters, up from 15.2% in the same period of 2024. This growth pushed the total share of low-carbon sources to 43% of global electricity supply.
| Technology | Capacity (GW) | Share of Renewables | Growth 2024 (GW) |
|---|---|---|---|
| Solar PV | 1,865 | 42% | +600 |
| Wind | 1,133 | 25% | +113 |
| Hydropower | 1,283 | 29% | +15 |
| Bioenergy | 151 | 3% | +4.6 |
| Other | 16 | <1% | +0.5 |
| Total | 4,448 | 100% | +585 |
The IEA projects that between 2025 and 2030, an additional 4,600 GW of renewable capacity will be added globally, nearly doubling the deployment pace of the previous five-year period (2019-2024). Solar PV is expected to represent nearly 80% of this expansion.
Investment in renewable energy reached unprecedented levels in 2025. Global renewable energy investments hit $386 billion in the first half of 2025, representing a 10% increase from the same period in 2024. Solar investment alone is expected to reach $450 billion for the full year, making it the single largest item in global energy investment.
However, this headline figure masks significant regional and sectoral variations. Asset finance for utility-scale solar and onshore wind fell 13% in H1 2025, reflecting an adverse policy environment in key markets, particularly the United States. This has prompted signs of capital reallocation from the US to Europe, with major developers like TotalEnergies and RWE reducing US activity while expanding in the North Sea.
Solar energy has emerged as the dominant force reshaping the global power system. In 2025, solar growth was more than three times larger than any other source of electricity, confirming its role as the primary driver of the energy transition.
The global solar PV market is expected to grow by 10% in 2025, reaching 655 GW under the medium scenario. This follows extraordinary growth of 85% in 2023 and 33% in 2024, representing a continuation of the deceleration trend but from a substantially higher base.
| Scenario | 2025 (GW) | 2029 (GW) | CAGR |
|---|---|---|---|
| High Scenario | 774 | 1,100+ | 30% |
| Medium Scenario | 655 | 930 | 10% |
| Low Scenario | 548 | 750 | -8% |
China continues to dominate the global solar market, adding 357.3 GW in 2024 and reaching over 1 TW of cumulative capacity. Remarkably, China now hosts almost half of global PV capacity. The rest of the world added 244.6 GW in 2024, with significant growth in India, Brazil, and emerging markets across Southeast Asia and the Middle East.
Meeting the Global Solar Council's aspirational target of 8 TW by 2030 will require a significantly accelerated pace of deployment, approximately 1 TW of new installations per year on average. Current trajectories suggest the industry is on track to reach this goal only under the most optimistic scenarios.
The solar industry in 2025 faces a complex policy landscape. In the United States, the new tax law (One Big Beautiful Bill Act) rolled back many clean energy tax credits and imposed new restrictions, pressuring early-stage solar pipelines. Wind and solar investments in H1 2025 fell 18% to nearly $35 billion compared to the same period in 2024.
Despite these headwinds, solar maintains its cost competitiveness. Fixed-mount solar now offers a levelized cost of energy (LCOE) ranging from $30 to $80 per MWh, compared to natural gas combined cycle's range of $61 to $126 per MWh. This cost advantage continues to drive corporate procurement, with corporate power purchase agreements (PPAs) accounting for 30% of global renewable capacity expansion to 2030.
Key trends shaping the solar market include:
Wind energy experienced strong growth in 2025, with global installations rising by 64% in the first half of the year compared to the same period in 2024. A total of 72.2 GW of new capacity was added between January and June 2025, bringing total installed wind power capacity to 1,245 GW by mid-2025.
Onshore wind has shown remarkable resilience and growth momentum. GWEC Market Intelligence expects new installations to surpass the previous record and reach 139 GW in 2025. Under current policies, 981 GW of new capacity is likely to be added through 2030, representing a compound annual growth rate (CAGR) of 8.8%.
Germany awarded nearly 11 GW of new onshore wind capacity in tenders in 2025, an all-time high representing a 70% year-on-year increase. This surge results mainly from permitting condition improvements that addressed years of undersubscribed auctions.
| Metric | Value | YoY Change |
|---|---|---|
| H1 2025 Additions | 72.2 GW | +64% |
| Total Installed (June 2025) | 1,245 GW | +13.5% |
| Global Electricity Share | ~12% | +1.2 pp |
| China H1 Additions | 51.4 GW | +100%+ |
| US 2025 Additions | 8.1 GW | +36% |
The United States is on track to add 46 GW of new wind capacity from 2025 to 2029. The 2025-2027 pipeline is fully committed, with all projects having turbine orders in place. More than 60% of the three-year capacity outlook has been commissioned or is under construction.
While onshore wind shows strong momentum, the offshore wind sector faces significant headwinds. The IEA revised its global offshore wind capacity forecast down by 27% from last year, reflecting policy changes in the United States, macroeconomic pressures, and supply chain challenges.
Offshore wind capacity expansion is expected to reach 140 GW over the 2025-2030 forecast period, more than doubling the growth of the previous five-year period. However, the annual offshore wind market is projected to expand from 9.2 GW in 2024 to over 37 GW by 2030, with China accounting for almost 50% of this increase.
Key challenges facing the offshore wind sector include:
Despite these challenges, the medium-term outlook remains optimistic. The annual offshore wind market is expected to approach 14.6 GW by 2030 in Europe, with significant growth potential in Asia-Pacific markets including Japan, South Korea, and Vietnam.
The renewable energy landscape in 2025 is characterized by significant regional divergence, with growth trajectories varying widely based on policy frameworks, market maturity, and economic conditions.
China continues to account for nearly half of global renewable capacity additions. The country has passed 1.6 TW of operating wind and solar projects, including 489 GW of distributed solar. China's annual solar installations reached 357.3 GW in 2024, representing nearly 60% of new global capacity.
However, China's growth outlook has been revised downward due to a shift from fixed tariffs to auctions, impacting project economics. The IEA's accelerated-case scenario for China assumes faster implementation of auctions and market reforms, which could unlock an additional 334 GW of capacity.
The US renewable forecast has been revised down by almost 50% due to several policy changes, including the earlier phase-out of federal tax credits, new import restrictions, suspension of new offshore wind leasing, and restrictions on permitting onshore wind and solar projects on federal land.
Despite these headwinds, the US achieved record capacity additions in 2025, with 50.3 GW of solar, wind, and battery storage added. Solar led with 43.4 GW (51%), followed by battery storage at 24.3 GW (28%), and wind at 11.8 GW (14%).
The European Union's growth forecast has been revised slightly upward due to higher-than-expected utility-scale solar PV capacity installations, driven by strong corporate PPA activity in Germany, Spain, Italy, and Poland. This offsets a weaker outlook for offshore wind.
Germany's remarkable 70% increase in onshore wind tender awards demonstrates the potential for policy reforms to unlock growth. However, the G7's wind and utility-scale solar pipeline has remained mostly unchanged at around 520 GW since 2023, highlighting the implementation gap.
India's renewable expansion is driven by higher auction volumes, new support for rooftop solar projects, and faster hydropower permitting. The country is on track to meet its 2030 target and become the second-largest growth market for renewables, with capacity set to rise by 2.5 times in five years.
Other emerging markets showing strong momentum include Brazil, which passed legislation on offshore wind and green hydrogen, and Vietnam, which introduced a target of 6-17 GW of offshore wind capacity by 2035.
The renewable energy sector in 2025 stands at an inflection point. While absolute capacity additions have reached record levels, the industry faces increasing headwinds from policy uncertainty, supply chain constraints, and macroeconomic pressures. The path to tripling global renewable capacity by 2030 remains achievable but requires accelerated deployment and policy support.
Grid Integration Becomes Critical: By 2030, variable renewables will generate almost 30% of global electricity supply, double today's level. This transformation calls for a rapid increase in power system flexibility and grid investment. Curtailment levels have been rising in many markets, and the number of hours with negative prices has surged across multiple countries.
Energy Storage Essential: Battery storage has emerged as a central component of new capacity, with a record 15 GW added in the US alone in 2025, up 35% year-on-year. Investment in battery storage surged above $65 billion globally this year.
Regional Diversification: While China and the US remain the largest markets, emerging economies are becoming increasingly important. Companies should position for growth in India, Southeast Asia, Latin America, and the Middle East.
Policy Risk Management: The divergence in policy trajectories between regions creates both risks and opportunities. Companies should diversify geographic exposure and develop scenario-based planning capabilities.
The IEA projects that under current policies, global renewable capacity will reach approximately 11,500 GW by 2030, falling short of the tripling target. However, under an accelerated case that assumes governments address key policy, grid integration, financing, and permitting challenges, cumulative renewable electricity capacity could reach over 10,400 GW, bridging most of the gap.
The renewable energy industry has demonstrated remarkable resilience and growth capacity. With the right conditions in place, the industry stands ready to deliver the scale of deployment necessary to meet global climate goals while providing affordable, reliable energy to power economic development worldwide.
