Solar generation met 61% of the increase in US electricity demand in 2025, according to new analysis from Ember.
US electricity demand rose by 135TWh in 2025, while solar generation increased by a record 83TWh, Ember said.
Dave Jones, chief analyst at Ember, added: “Solar growth was essential in helping to meet fast-rising US electricity demand in 2025. It generated where it was needed, and – with the surge in batteries – increasingly when it was needed.”
Solar grew most in Texas, the Midwest and the Mid-Atlantic, which also saw the largest rises in electricity demand.
Solar growth met 81%, 81% and 33% of demand growth respectively in those three regions, according to the analysis.
It also met all daytime demand growth between 10:00 and 18:00 ET and some evening demand due to rising battery capacity.
Ember said batteries are increasingly turning solar from daytime power into dispatchable all-day electricity.
Most new solar generation in 2025 was absorbed by rising electricity demand rather than displacing existing supply.
Jones stated: “Solar has the potential to meet all the rise in electricity demand and much more. With electricity demand surging, the case to build solar has never been stronger.”
