Global Market Outlook and Strategic Insights
Finding 1: Global renewable capacity reached a record 4.4 TW by end of 2024, representing 46% of total global installed power capacity.
The renewable energy sector experienced unprecedented growth in 2024-2025, with capacity additions of 585 GW in 2024 alone marking a 15% year-on-year increase. Solar and wind technologies dominated new installations, jointly accounting for 97.5% of all net renewable additions.
Finding 2: Solar and wind supplied 17.6% of global electricity in the first three quarters of 2025, up from 15.2% in the prior year.
For the first time, renewables including solar, wind, hydro and geothermal generated more electricity than coal on a sustained basis. Solar growth was more than three times larger than any other electricity source, confirming its role as the dominant force reshaping the global power system.
Finding 3: Global energy transition investment reached a record $2.3-2.4 trillion in 2025, though growth momentum is slowing.
While investment levels hit new records, the pace of growth decelerated from 24-29% annually in previous years to just 8-11% in 2025. Renewable energy investment specifically fell 9.5% year-on-year to approximately $690 billion, reflecting policy uncertainty and market adjustments.
Finding 4: The IEA projects 4,600 GW of renewable additions between 2025-2030, but this remains below the tripling target needed by 2030.
Current trajectories suggest global renewable capacity will reach approximately 10.3-11.5 TW by 2030, falling short of the 11 TW target established at COP28. Achieving the tripling goal would require accelerating annual growth to 16.6%.
The global energy transition accelerated significantly in 2025, with renewable energy technologies cementing their position as the dominant source of new power capacity worldwide. According to data from the International Renewable Energy Agency (IRENA) and the International Energy Agency (IEA), the sector has reached critical milestones that signal a fundamental shift in the global energy landscape.
By the end of 2024, global renewable electricity generation capacity stood at approximately 4.4 terawatts (4,443 GW), representing about 46% of total global installed power capacity. This marks an unprecedented 15.1% increase from 2023, significantly higher than the 10.4% compound annual growth rate observed over the preceding five years.
The composition of renewable capacity has shifted dramatically toward variable renewable sources. Solar and wind now account for 67.5% of total renewable capacity, up from previous years. Solar alone added 453 GW in 2024, while wind contributed 114 GW. Together, these technologies represented 92.5% of all new power capacity additions globally.
| Technology | Capacity (GW) | Share of Renewables | YoY Growth |
|---|---|---|---|
| Solar PV | 1,866 | 42% | +32% |
| Hydropower | 1,277 | 29% | +1.1% |
| Wind | 1,133 | 25% | +11% |
| Bioenergy | 151 | 3% | +2% |

Global investment in the energy transition reached a record $2.3-2.4 trillion in 2025, according to BloombergNEF and IRENA data. However, the pace of growth has decelerated significantly. While investment more than doubled since 2020, annual growth slowed from 24-29% in previous years to just 8-11% in 2025.
The renewable energy sector specifically saw investment of approximately $690-807 billion in 2025, representing about one-third of total energy transition investment. Notably, renewable energy investment fell 9.5% year-on-year, reflecting changing power market regulations and policy uncertainty in key markets including China.
| Sector | Investment ($ Billion) | YoY Change |
|---|---|---|
| Electrified Transport | 893 | +20% |
| Renewable Energy | 690 | -9.5% |
| Power Grids | 483 | +15% |
| Energy Storage | 66 | +35% |
Solar photovoltaic technology has emerged as the undisputed leader in renewable energy deployment, driving the majority of capacity additions and reshaping electricity markets worldwide. In 2025, solar continued its exponential growth trajectory while facing new challenges related to grid integration and policy uncertainty.
Solar energy commanded the largest share of renewable investment in 2025, with approximately $450 billion in new capital deployment. The technology's cost competitiveness has improved dramatically, with module costs falling 83% since 2010, making solar the most cost-competitive energy source in many markets.
In the United States, solar led new capacity additions with 27 GW of utility-scale capacity commissioned in 2025, representing 51% of all renewable additions. The U.S. market added a total of 50.3 GW across solar, wind, and battery storage combined, marking the first time annual deployment reached this milestone.
China remains the dominant player in global solar markets, accounting for nearly half of global solar capacity. By mid-2025, China's combined wind and solar capacity reached 1.67 TW, surpassing thermal power capacity for the first time. The country is targeting 240 GW of energy storage by 2030 to stabilize supply from variable renewable sources.
Technological innovation continues to drive solar efficiency improvements and cost reductions. In 2025, LONGi Solar set a world record with its TOPCon modules achieving 25.58% efficiency, demonstrating the ongoing potential for performance improvements.
The solar industry is also expanding into new applications, including agrivoltaics (combining solar panels with agriculture) and floating solar installations. These innovations address land use constraints while providing additional value streams.
However, the sector faces headwinds including:
Wind energy, both onshore and offshore, continues to play a critical role in the global energy transition. While facing more significant headwinds than solar in 2025, wind power remains essential for achieving climate targets due to its higher capacity factor and complementary generation profile.
Onshore wind experienced a resurgence in auction activity during the first half of 2025. For the first time, onshore wind accounted for approximately 33% of global auction volumes, matching awarded solar PV capacity. This surge resulted mainly from permitting improvements that addressed years of undersubscribed auctions, particularly in Germany.
The United States added 11.8 GW of wind capacity in 2025, representing 14% of total renewable additions. However, the global wind pipeline showed concerning trends, with year-on-year growth slowing from 22% in 2024 to 11% in 2025. Wind projects specifically experienced a 13% drop in pipeline growth compared to a 7% drop for solar.
| Region | Onshore Wind (GW) | Offshore Wind (GW) | Total |
|---|---|---|---|
| China | 45 | 6 | 51 |
| Europe | 12 | 4 | 16 |
| United States | 10 | 0.5 | 10.5 |
| Rest of World | 18 | 1.5 | 19.5 |
Offshore wind faced significant challenges in 2025, with the IEA revising its five-year growth forecast downward by 27%. Policy changes in the United States, macroeconomic pressures, and supply chain challenges raised costs and undermined project bankability in several European markets and Japan, resulting in undersubscribed auctions and project cancellations.
Despite these headwinds, offshore wind capacity expansion is still expected 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 projected 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 offshore wind market is expected to approach 14.6 GW by 2030. However, auction volumes plummeted to just 2.5 GW in the first half of 2025, raising concerns about the pipeline needed to meet 2030 targets.
The renewable energy sector in 2025 presents a picture of remarkable achievement alongside significant challenges. While capacity additions and investment levels reached new records, the pace of growth is slowing, and current trajectories remain insufficient to meet global climate targets.
1. The renewable transition is accelerating but uneven. Solar and wind now supply nearly 18% of global electricity and have overtaken coal generation. However, growth is concentrated in China, the United States, and Europe, leaving most emerging economies behind.
2. Investment momentum is slowing. Despite record absolute levels, the deceleration in renewable investment growth—from 32% annually to just 7-8%—signals market maturation and policy headwinds. The $5.6 trillion annual investment needed through 2030 remains far from reach.
3. Technology leadership is consolidating. Solar dominates new capacity additions, while wind faces structural challenges. Energy storage is emerging as a critical enabler, with record 15 GW added in the U.S. alone in 2025.
4. Policy uncertainty is the primary risk. Trade tensions, permitting delays, and shifting regulatory frameworks in major markets are creating uncertainty that could stall deployment. Business certainty is essential for maintaining investment flows.
The IEA projects that renewable power capacity will increase by approximately 4,600 GW between 2025 and 2030—double the deployment of the previous five years. However, even this ambitious scenario falls short of the tripling target established at COP28.
To bridge the gap, annual renewable capacity additions would need to accelerate to 16.6% growth rates in the remaining years—significantly above current trends. Achieving this will require:
The renewable energy transition has reached an inflection point. The technologies are proven, costs are competitive, and demand is growing. The challenge now is execution—scaling deployment fast enough to meet climate commitments while managing the integration of variable sources into existing power systems.
