Renewables, including solar, wind, hydro, biofuels and others, are at the centre of the transition to a less carbon-intensive and more sustainable energy system.

Renewable capacity growth between 2019 and 2024 by technology


Solar PV drives strong rebound in renewable capacity additions

Renewable power capacity is set to expand by 50% between 2019 and 2024, led by solar PV. This increase of 1 200 GW is equivalent to the total installed power capacity of the United States today. Solar PV alone accounts for almost 60% of the expected growth, with onshore wind representing one-quarter.

Renewable electricity generation by region and scenario, 2018-2040


Renewables play a leading role in energy transitions

Cost reductions in renewables and advances in digital technologies are opening huge opportunities for energy transitions. Wind and solar PV provide more than half of the additional electricity generation to 2040 in the Stated Policies Scenario and almost all the growth in the Sustainable Development Scenario.

Share of renewables in power generation in the Sustainable Development Scenario, 2000-2030


Renewable power needs to expand significantly to meet the IEA Sustainable Development Scenario share of half of generation by 2030

In 2018, renewable electricity generation rose 7%, with wind and solar PV technologies together accounting for 60% of this increase. Although the share of renewables in global electricity generation reached 26% in 2018, renewable power as a whole still needs to expand significantly to meet the Sustainable Development Scenario share of half of generation by 2030. This requires the rate of annual capacity additions to accelerate; however, renewable capacity growth stalled in 2018 for the first time since 2001.
