May 2026 marked a historic milestone for US energy. Data from global energy think tank Ember showed solar power generation reached 12.8% of total electricity, overtaking coal at 12.2% for the first time in any single month. Coal's monthly share hit its fourth-lowest level on record. Solar also became the third-largest electricity source nationwide, after natural gas and nuclear. Coal had already posted its lowest-ever monthly output in April; May saw a slight rebound, but the long-term decline remains intact.
Structural victory: monthly record is just the start
Nicolas Fulghum, senior energy analyst at Ember, noted that solar has been steadily rising in the US power mix for years. Coal first lost its top spot and has been sliding annually. He predicted more monthly solar surpassings ahead, with annual dominance possible within a few years. Solar has led new power capacity additions for five consecutive years. In Q1 2026, solar and battery storage together accounted for 91% of new generating capacity—nearly nine out of ten new plants are solar or storage-related. The International Energy Agency (IEA) projects renewables will reach nearly 45% of global electricity by 2030.
Trump’s coal push: $700M subsidies clash with market reality
The political winds in Washington blow the opposite direction. Last week, the Trump administration announced nearly $700 million in support for coal plants and exports, aiming to revive the struggling US coal industry. Trump said at a White House event: “Coal is a good business. When it comes to electricity, nothing really beats it.” White House spokesperson Taylor Rogers argued the policy strengthens national security, prevented retirement of over 17 GW of power capacity, and saved lives during peak demand. Meanwhile, the administration has canceled multiple solar and wind projects, slowed clean energy permitting, and terminated $7 billion in affordable solar subsidies. Yet Martin Pochtaruk, CEO of Canadian solar panel maker Heliene, countered: “Trump can say coal is coming back, but investors will put money where returns are best, and in power generation that’s solar, making it the fastest-growing fuel.”
AI and manufacturing surge: grid faces biggest demand shock in two decades
While supply transforms, demand is fundamentally shifting. After roughly two decades of flat electricity consumption, the US is seeing rapid growth driven by AI data centers, manufacturing reshoring, and electrification of transport and heating. The US Energy Information Administration (EIA) forecasts data center power consumption to rise 133% by 2030, reaching 426 TWh, or about 9% of total US electricity. AI server power use is expected to jump from 93 TWh in 2025 to 432 TWh in 2030, nearly a fivefold increase. Carnegie Mellon University research warns that soaring data center and crypto mining demand could raise average US household electricity bills by 8% by 2030, with high-demand states like Virginia seeing hikes exceeding 25%. The inertia of the energy transition now outweighs any single administration's policy interventions.
