Americans’ electricity bills are up. Don’t blame AI

POWER BILLS are going up in America and the people are angry. They know whom to blame—the bosses of technology firms thirsting for more juice to fuel artificial-intelligence data centres. Ashburn, a town of 45,000 in a featureless part of Virginia that has earned the nickname “Data Centre Alley”, has some 150 of these. They consume roughly as much electricity as Philadelphia, a city of 1.6m. On March 4th Donald Trump convened tech leaders to sign a pledge to “build, bring or buy their own power supply…ensuring that Americans’ electricity bills will not increase”.
