Global Market Analysis and Strategic Outlook
Solar and Wind Energy Transformation
Solar and wind energy are now expanding fast enough to meet all new global electricity demand, a milestone reached in the first three quarters of 2025.
Together, solar and wind supplied 17.6% of global electricity in the first three quarters of 2025, up from 15.2% over the same period last year, pushing the total share of low-carbon sources to 43%.
Solar power generation surged by 498 TWh (+31%) in the first three quarters of 2025, already surpassing total solar output for all of 2024.
This growth was more than three times larger than any other source of electricity, confirming solar's role as the dominant force reshaping the global power system.
Global renewable capacity reached 4.4 TW by end of 2024, with 793 GW of new capacity expected in 2025.
The world is set to add 793 GW of renewable capacity in 2025, up 11% from the 717 GW added in 2024, marking an unprecedented expansion in clean energy deployment.
The renewable energy sector has entered a transformative phase in 2025, characterized by unprecedented growth rates, shifting investment patterns, and evolving policy landscapes. According to the International Renewable Energy Agency (IRENA), renewable capacity reached 4.4 terawatts (TW) by the end of 2024, representing 46.2% of total global installed power capacity.
The year 2024 witnessed the largest increase in renewable energy capacity to date, with 585 GW of new capacity added globally. This represents a 15.1% year-on-year increase, significantly higher than the 10.4% compound annual growth rate observed over the preceding five years (2018-2023).
| Technology | Capacity (GW) | Share of Renewables | YoY Growth |
|---|---|---|---|
| Solar PV | 1,866 | 42.0% | +32.0% |
| Hydropower | 1,277 | 28.7% | +1.1% |
| Wind | 1,133 | 25.5% | +11.2% |
| Bioenergy | 151 | 3.4% | +4.8% |
| Geothermal | 15 | 0.3% | +0.3% |
Solar and wind energy continued to dominate renewable capacity expansion, jointly accounting for 97.5% of all net renewable additions in 2024. Solar alone increased by 453 GW, while wind added 114 GW. The share of variable renewables (wind and solar) increased to 67.5% of total renewable capacity, indicating a fundamental shift toward these more intermittent energy sources.
Global investment in clean energy reached a new record of $2.3 trillion in 2025, representing an 8% increase from 2024 levels. According to BloombergNEF's Energy Transition Investment Trends report, this growth demonstrates continued global commitment to decarbonization despite economic uncertainty and shifting policy environments.
Despite record investment levels, BloombergNEF analysis indicates that annual clean energy spending needs to average $5.6 trillion between 2025 and 2030 to align with net-zero by 2050 pathways—a 168% increase from 2024 figures.
Renewable energy investments set another record in the first half of 2025, rising 10% from the same period of last year to reach $386 billion. However, asset finance for utility-scale solar and onshore wind was down 13%, reflecting an adverse policy environment in some key markets. Investors are increasingly rethinking capital allocation and putting money where project returns are strongest.
Solar energy has emerged as the undisputed leader in the global energy transition, with growth rates exceeding all other generation sources. The technology's cost competitiveness, scalability, and rapidly improving efficiency have positioned it as the primary driver of renewable energy expansion.
In the first three quarters of 2025, solar generation rose by 498 TWh (+31%), already surpassing the total solar output recorded for all of 2024. This growth was more than three times larger than any other source of electricity, confirming solar's role as the dominant force reshaping the global power system.
| Source | Generation Increase (TWh) | Growth Rate |
|---|---|---|
| Solar | +498 | +31.0% |
| Wind | +137 | +7.6% |
| Total Renewables | +635 | — |
| Global Demand Increase | +603 | +2.7% |
Together, solar and wind added 635 TWh of generation, outpacing the rise in global electricity demand of 603 TWh (+2.7%). This marks the first time across a sustained period that renewables have grown faster than demand itself, signaling a fundamental shift in the global power sector.
In 2025, solar strengthened in markets that had long trailed behind global leaders, demonstrating solar's potential to leapfrog fossil generation in emerging markets. Several countries outside traditional frontrunners like China and Europe are now recording sharper growth thanks to falling costs, easing supply bottlenecks, and clearer policy signals.
The United States built the most new power-generating capacity in more than two decades in 2025, with 54 GW of new utility-scale generation and storage capacity commissioned. Renewables accounted for 61% of new capacity, with utility-scale solar specifically leading with 27 GW alternating current commissioned.
China continues to dominate global solar deployment, accounting for nearly half of global solar capacity. The country's wind and solar pipeline grew from 1.2 TW to 1.5 TW in 2025, and China has now passed 1.6 TW of operating wind and solar projects.
While wind energy continues to play a crucial role in the renewable energy mix, the sector faces distinct challenges compared to solar. Wind developers experienced political barriers and a streak of failed wind power auctions in 2025, with year-on-year growth in the wind pipeline slowing more pronouncedly than solar.
Onshore wind demonstrated notable progress in 2025, with awarded auction volumes showing a significant shift in technology shares. Onshore wind accounted for around 33% of global auction volumes in the first half of 2025—the highest awarded capacity in any six-month period before 2024, and for the first time similar to awarded solar PV capacity.
This surge results mainly from permitting condition improvements that addressed years of undersubscribed auctions, especially in Germany. These improvements have unlocked significant project potential that had been stalled by regulatory bottlenecks.
The offshore wind industry faces multiple challenges, with forecast growth over the next five years revised down by more than 25% compared to previous projections. 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.
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 has been revised down 27% from last year's forecast due to undersubscribed auctions and project cancellations.
Offshore wind auction volumes plummeted to 2.5 GW in the first half of 2025. Several developers have reduced their 2030 deployment targets, and signs of capital reallocation from the US to Europe are emerging as investors seek more stable returns.
The renewable energy sector's growth in 2025 came even as the industry grappled with uncertainty driven by federal policy changes. In the United States alone, no less than 87 new trade and tariff policies were announced in 2025, creating unpredictability for companies and investors with exposure to cleantech supply chains.
Businesses relying on the 10-year timeline of federal tax incentives enacted in 2022 had to adjust development plans as many credits were abruptly phased out in late 2025. Federal permitting revocations and restrictions, especially impacting wind and solar projects, have added additional delays to already lengthy approval timelines.
| Region | 2024 Pipeline | 2025 Pipeline | Growth |
|---|---|---|---|
| China | 1.2 TW | 1.5 TW | +25% |
| G7 Countries | ~520 GW | ~520 GW | 0% |
| Rest of World | 2.7 TW | 2.9 TW | +7% |
| Global Total | 4.4 TW | 4.9 TW | +11% |
The G7's wind and utility-scale solar pipeline has remained mostly unchanged at around 520 GW since 2023, despite IRENA's calls on G7 countries to more than double their annual renewable energy capacity additions through 2030. This misalignment between current pipelines and required progress represents a significant challenge for meeting global climate targets.
The renewable energy sector stands at a critical juncture in 2025. While solar and wind have demonstrated their ability to outpace global electricity demand growth, significant challenges remain in scaling deployment to levels required for net-zero alignment.
The International Energy Agency projects that renewable power capacity will increase by approximately 4,600 GW between 2025 and 2030—double the deployment of the previous five years. Growth in utility-scale and distributed solar PV more than doubles, representing nearly 80% of worldwide renewable electricity capacity expansion.
To achieve the COP28 goal of tripling global renewable capacity to 11 TW by 2030, the world needs to add approximately 1,070 GW annually. At current growth rates, the world will only reach 10.3 TW, missing the target by 0.9 TW. Achieving the target would require renewable capacity to expand at 16.6% annually—faster than the current 15.1% growth rate.
Key strategic imperatives for the sector include:
The data from 2025 provides compelling evidence that renewable energy has reached an inflection point. Solar and wind are no longer just catching up—they are outpacing demand growth itself. However, realizing the full potential of the energy transition will require sustained policy support, continued cost reductions, and massive capital mobilization at unprecedented scale.
