Global electricity demand growth in the first half of 2025 was met entirely by solar and wind power, marking a historic shift toward clean energy and the first recorded decline in fossil fuel generation, according to a new report from energy think tank Ember.

The report revealed that solar and wind generation grew fast enough to not only meet the world’s rising electricity demand but also displace a portion of fossil fuel generation. Global electricity demand rose 2.6%, or 369 terawatt-hours (TWh), in the first half of 2025. Of this, solar alone supplied 83% of the increase, with record output of 1,303 TWh—up 31% year-on-year—while wind generation rose 7.7% to 1,365 TWh. Advertisement

As a result, coal generation fell 0.6% (–31 TWh) and gas declined 0.2% (–6 TWh), pushing global power s
