The global renewable energy landscape is undergoing a historic transformation, with new data showing solar and wind power growing fast enough to outpace rising electricity demand.
According to Emberâs H1 2025 analysis, their combined growth exceeded global demand growth by 109%, with solar alone meeting 83% of the increase. This surge pushed renewables past coal for the first time on record, now supplying 34.3% of the worldâs electricity compared to coalâs 33.1%.
Solar generation rose by 306 TWh (+31%), driven largely by Chinaâs 55% share of the increase, followed by the United States, European Union, India and Brazil.
For the worldâs largest renewable energy companies, these figures signal a turning point â one where clean technologies are no longer marginal but central to the global power mix, accelerating a shift toward affordable, reliable and sustainable electricity on an unprecedented scale.
Ranked by market capitalisation, this list explores the largest renewable energy companies in the world.
