In all, the United States generated a record 756,621 gigawatt-hours from both solar and wind last calendar year. That’s enough to power the equivalent of more than 70,000,000 average American homes. Solar and wind combine to account for a record 17% of the total generation in the U.S. in 2024.

Solar is the fastest-growing source of electricity in the U.S. with growth occurring in all 50 states over the last 10 years.

The two renewable energy sources accounted for 17% of the country’s power mix while coal fell to a low of 15%. Natural gas remains by far the largest source of electricity, accounting for 43%.

In a first for the US, wind and solar produced more electricity than coal last year, according to a new report from energy think tank Ember. Coal fell to a historic low, generating 15 percent of the country’s electricity compared to 17 percent from solar and wind combined.
