Renewable energy currently powers about one-third of global electricity generation, with renewables providing 30% of electricity worldwide as of 2022. However, renewables comprise only 13% of total final energy consumption. Solar leads growth at 1,018 gigawatts capacity, followed by wind at 837 gigawatts, while hydropower remains the largest contributor at 16.8% of global electricity. Experts project renewables will reach 35% of electricity generation by 2025 and potentially 46% by 2030.
The world’s evolution toward renewable energy continues to gain momentum, with clean power sources now providing nearly one-third of global electricity. Recent data shows renewables generated 30% of global electricity in 2022, a slight increase from 29% in 2020. However, when considering total final energy consumption—which includes heating, transportation, and industry—renewables account for just 13% as of 2023.
Solar power is leading the renewable energy surge. Global solar capacity reached 1,018 gigawatts in 2022, with installations growing by 40% that year. In 2023, the world added 473 gigawatts of renewable capacity, with solar making up 347 gigawatts—over 73% of new additions. Experts predict solar will surpass hydropower as the largest renewable electricity source by 2030. In the United States, solar is expected to account for over 50% of new electricity generating capacity in 2023.
Wind energy is also making significant progress. Global wind capacity hit 837 gigawatts in 2022, with generation increasing by 17% that same year. Offshore wind grew by 75% between 2020 and 2022. The increasing focus on offshore wind has been particularly notable in Europe, where capacity is set to double by 2025. By 2026, wind is expected to generate more electricity than nuclear power plants worldwide.
Currently, hydropower remains the largest renewable electricity source, generating 4,330 terawatt-hours in 2022 and accounting for 16.8% of global electricity. However, its share is expected to decline slightly by 2030 as solar and wind expand faster. In fact, combined wind and solar generation surpassed hydropower in 2024. This shift is driving economic stability by reducing dependence on imported fuels and creating new jobs across various sectors.
China leads the global transformation, accounting for 60% of new renewable capacity additions. Europe generates 40.5% of its electricity from renewables, while South America leads all regions with 75% renewable electricity.
Looking ahead, renewables are projected to provide 35% of global electricity by 2025 and 46% by 2030. Some experts believe renewables could generate up to 90% of the world’s electricity by 2050.
However, challenges remain, including the need for energy storage, grid flexibility improvements, and addressing renewable curtailment issues in some regions. Despite these hurdles, the renewable energy market is forecast to grow at 17.2% annually through 2030.
