As the U.S. men's national soccer team kicks off its first match against Paraguay in Southern California on Friday night, large swaths of the country are trapped in what feels like a wet sauna, with dangerous heat and humidity forcing households to crank up their air conditioning and straining power grids from the Southeast to the Northeast.On Thursday, the Department of Energy issued an emergency order to mitigate blackout risks across the Carolinas amid extreme heat that threatens to sharply increase power demand.The order, issued under Section 202(c) of the Federal Power Act, allows Duke Energy Carolinas and Duke Energy Progress to run certain generating units at maximum output.Secretary of Energy Chris Wright stated, "Maintaining affordable, reliable, and secure power in the Duke Energy service territory is non-negotiable.""The previous administration's energy subtraction policies weakened the grid, leaving Americans more vulnerable during events like this. Thanks to President Trump's leadership, we are reversing those failures and using every available tool ensuring Americans in the Carolinas' have continued access to affordable, reliable, and secure energy to power and cool their homes," Wright said.⚠️🔥 One day left of the oppressively hot and humid conditions. A few severe storms will be possible again this afternoon and evening, but not everyone will get a storm. It will turn much less humid for Saturday, but high temperatures will remain in the upper 80s to near 90°. pic.twitter.com/pi6sJDUwKp
