As the U.S. faces a blisteringly hot summer, millions of people already reeling from the coronavirus’s economic fallout are about to face sharp increases in electric bills that may drive some to the brink of financial ruin. With soaring temperatures expected in July and August, people stuck at home because they’re unemployed or working remotely will depend on air conditioners more than ever. That’s going to drive up power bills by as much as 25% in parts of the U.S. at a time when they were already a significant hardship for about 50 million people, according to analyst estimates and the U.S. Department of Energy.

“There will be people faced with figuring out whether to pay their bill or put food on the table,” said Sindy Benavides, chief executive officer of the League of United Latin American Citizens, a Washington-based civil rights group. “It’s a storm waiting to happen.”
