Washington DC, April 4th – The US hit a new record low for fossil fuels in the electricity mix last month as solar and wind reached a record high, according to new data from global energy think tank Ember. In March 2025, fossil fuels accounted for less than 50% (49.2%) of electricity generated, for the first month on record. This surpasses the previous monthly record low of 51% set in April 2024. The shift meant that clean sources generated more than half (50.8%) of US electricity for the first month on record. The record was driven largely by an increase in wind and solar power, which reached a record 24.4% of US electricity in March 2025. In March 2025, US solar power increased a staggering 37% (+8.3 TWh) compared to March 2024. Wind power increased by 12% (+5.7 TWh). Together wind and solar reached an all-time high, generating 83 TWh of US electricity, 11% higher than the previous record of 75 TWh set in April 2024. In comparison, fossil generation fell by 2.5% (-4.3 TWh) compared ... Read full article.
