01 Industry overview

The clean energy industry at a glance

Clean energy is scaling rapidly: global investment is estimated at $2.2 trillion in 2025, while renewables supplied 33.8% of global electricity generation and added 692 GW of capacity.

Market size
The market value of six major clean energy technologies—solar PV, wind, electric cars, batteries, electrolysers and heat pumps—reached nearly $1.2 trillion in 2025. This measure covers technology markets rather than the full value of clean-energy investment, generation and infrastructure.[1]
Forecast & CAGR
Under the IEA’s Stated Policies Scenario, the market value of major clean energy technologies approaches $3 trillion by 2035, up from nearly $1.2 trillion in 2025. This implies an approximate compound annual growth rate of 9.6% over 2025–2035; the CAGR is calculated from the IEA’s endpoint values.[1]
Market share & regions
China, the United States and the European Union together accounted for 550 GW, or 79.5%, of new renewable capacity installed in 2025. Africa added 11.3 GW, representing 1.6% of global additions.[13]
Segmentation
Solar PV accounted for about 510 GW, or nearly three-quarters, of renewable capacity additions in 2025, while wind added 159 GW. Solar PV therefore remained the largest growth segment, followed by wind, with hydropower, bioenergy, geothermal, concentrating solar power and marine energy making up the remainder.[13][1]
Key players & concentration
The renewable power market is geographically concentrated in new capacity deployment: China, the United States and the European Union represented 79.5% of global additions in 2025. China alone added nearly 500 GW, more than 60% of global renewable growth, according to the IEA.[13][1]
Pricing
In 2024, the global weighted-average levelised cost of electricity was $0.034 per kWh for new utility-scale onshore wind, $0.043 per kWh for solar PV and $0.057 per kWh for hydropower. IRENA reported that 91% of newly commissioned utility-scale renewable capacity was cheaper than the lowest-cost new fossil-fuel alternative.[13]
Trends, drivers & challenges
Electricity demand from industry, cooling, electric mobility, data centres and artificial intelligence is driving investment, with global energy-sector investment expected to reach $3.3 trillion in 2025. Key challenges include grid-connection delays, supply-chain pressures, financing costs, trade tariffs and the need to integrate variable solar and wind generation.[1][13]
Consumer behavior & competition
Electric cars represented around 25% of global car sales in 2025, reflecting growing consumer adoption of electrification. Competition is also intensifying in clean-technology manufacturing: investment in selected manufacturing capacity fell below $200 billion in 2024, while the United States and European Union together were estimated to account for about 30% of manufacturing investment in 2025.[1]
M&A
A major recent transaction was Constellation Energy’s planned acquisition of Calpine, announced in January 2025 at a net purchase price of $26.6 billion. The combined company is expected to serve 2.5 million homes and businesses and hold nearly 60 GW of zero- and low-emission generation capacity.[70]
Regulation
The European Commission launched its Clean Industrial Deal on 26 February 2025, including measures to accelerate renewable-energy deployment, industrial decarbonisation and clean-technology manufacturing. The related state-aid framework is intended to speed approval of support for renewable energy and strategic clean-tech capacity.[71]
Latest news
The latest global power data show that renewables overtook coal in 2025, supplying 33.8% of global electricity generation, or 10,730 TWh, compared with coal’s 33.0% and 10,476 TWh. Wind and solar alone reached 17.3% of global generation.[69]
