Solar beats coal in the US electricity mix for the first month ever

Solar generated more US electricity than coal for the first month on record in May 2026, according to new analysis from global energy think tank Ember. Solar supplied 12.8% of US electricity during the month, while coal dropped to 12.2%. more…

Why this matters
Why now

The increasing deployment of solar capacity and improving economics have reached a tipping point, allowing it to surpass coal in electricity generation for the first time.

Why it’s important

This event signifies a critical milestone in the global energy transition, demonstrating the diminishing role of fossil fuels and the ascendancy of renewable sources in major economies.

What changes

The US energy mix has demonstrably shifted, providing concrete evidence that solar is now a primary, rather than supplementary, source of electricity, directly displacing coal.

Winners
  • · Solar power developers
  • · Renewable energy investors
  • · Lithium-ion battery manufacturers
  • · Grid modernization companies
Losers
  • · Coal mining companies
  • · Coal-fired power plant operators
  • · Fossil fuel lobbying groups
  • · Regions dependent on coal extraction
Second-order effects
Direct

Further acceleration of renewable energy investments and development in the US.

Second

Increased pressure on natural gas as the next fossil fuel to be significantly displaced by renewables, alongside growing demand for grid flexibility and energy storage.

Third

Potential for the US to become a net exporter of renewable energy technologies and expertise, shifting geopolitical power dynamics related to energy independence.
