Tens of millions of Americans could be thrown into a summer of hell as a megadrought, heatwaves, and reduced power generation could trigger widespread rolling electricity blackouts from the Great Lakes to the West Coast, according to Bloomberg, citing a new report from the North American Electric Reliability Corporation (NERC), a regulatory body that manages grid stability.

NERC warned power supplies in the Western US could be strained this summer as a historic drought reduces hydroelectric power generation due to falling reservoir levels and what's expected to be an unseasonably hot summer. Compound the hellacious weather backdrop with grids decommissioning fossil fuel power plants to fight climate change and their inability to bring on new green power generation, such as solar, wind, and batteries, in time, is a perfect storm waiting to happen that will produce electricity deficits that may force power companies into rolling blackouts for stability purposes.
