Solar generated more power than coal for the first time in US history
At the same time that the Trump administration is pushing further toward coal power, announcing plans only last week to invest almost $700 million into reviving the industry, a key renewable energy source has just hit a major milestone in the US.
New data from energy think tank Ember, released Wednesday, shows that solar supplied 12.8% of US energy generation in May — marking not only the highest share ever recorded for the clean energy source, but also the first time that solar has generated more monthly energy than coal in the US, which supplied 12.2%.
The figure for May denotes the fourth-lowest monthly share that coal has ever seen, only slightly greater than the all-time low of 11.7% observed for April. From 1984 until 2010, coal was America’s largest source of energy. However, as the fossil fuel continues to fall out of favor, that share has been almost cut in half in the last five years alone.
Meanwhile, demand for renewables like solar has boomed as America’s energy use keeps surging to new highs. On top of surpassing coal last month, solar became the third-largest source of electricity overall in the US, behind natural gas and nuclear, and remains the nation’s fastest-growing power source, per Climate Central.
Even after the Trump administration terminated $7 billion in solar project funding last August, it seems the energy source remains a clear bright spot. Another report released this week from the Solar Energy Industries Association found that the US added 7.8 gigawatts of new solar capacity in the first quarter of 2026 across more than 6 million solar installations nationwide.
