Solar and hydroelectric generation expanded enough last year to displace coal even as total electricity demand grew. The grid's structural shift toward renewables is outpacing concerns about AI data center consumption. This matters because it shows the energy transition is now driven by supply-side economics—cheaper renewables—rather than policy mandates alone, making coal retirement increasingly inevitable rather than contested. The real tension is no longer whether coal loses market share, but whether utilities can retire plants fast enough to avoid stranded assets while meeting the uneven geographic demands of new compute infrastructure.
