AI’s energy demand leaves millions of US homes power-starved

America’s love affair with artificial intelligence comes with a bill far bigger than anyone expected. Reportedly, AI is draining the country’s electricity like a high-tech vampire.

As data centers multiply, guzzling more power than entire cities, millions of homes are getting hit with distorted power flows that wreak havoc on their appliances and jack up fire risks.

“Bad harmonics” is the name of this nightmare. Normally, electricity flows smoothly, like ocean waves. But when AI-fueled data centers crank up their demands, those waves turn chaotic, destabilizing everything downstream.

Think of it as a speaker blaring music so loudly it fries itself. That’s what’s happening to America’s power grid. Refrigerators start rattling, air conditioners overheat, and sparks can fly—literally.

Whisker Labs, a company tracking power quality with one million sensors across U.S. homes, has reportedly uncovered a grim reality. The closer a home is to a data center, the worse the distortions.

More than half of the homes with the worst power quality issues sit within 20 miles of a data center. That’s 3.7 million Americans caught in the crossfire of the AI boom.

Data centers are turning the grid into a ticking time bomb

Experts have been sounding the alarm about the impact of data centers for years, but AI has put this problem on steroids. These facilities are popping up like mushrooms, each demanding as much electricity as 10,000 homes. But the grid wasn’t built for this kind of pressure.

The AI frenzy has turned Northern Virginia into ground zero. Dubbed “data center alley,” the region now holds 3,000 megawatts of data center capacity—double that of Beijing, its closest competitor.

The power demands are so massive that Dominion Energy, the utility serving much of the area, is scrambling to build a new transmission line just to keep the lights on.

In Prince William County, sensors installed in homes within seven miles of data centers showed alarming distortion levels. The report says nearly 6% of these homes reported power quality so bad it risks frying appliances.

Some readings spiked as high as 12.9%, way beyond the 8% threshold where equipment starts failing. Meanwhile, York County, 80 miles from the nearest major data center, reported steady, low distortion levels. The connection is undeniable.

AI is pushing America to the brink

America’s grid was already hanging by a thread before AI came into the picture. Decades of underinvestment in infrastructure mean the system is aging and fragile. Now, electricity demand is set to spike by 16% over the next five years, with AI-driven data centers driving most of the growth.

This isn’t just a city problem either. Even rural areas near data centers are seeing distorted power flows. A Bloomberg analysis showed that homes close to data centers had way worse power quality, even if they were in low-density areas.

Bad harmonics also lead to billions of dollars in equipment failures, repairs, and lost productivity. It’s a slow bleed that’s adding up fast. Utilities like Dominion Energy and Exelon’s Commonwealth Edison are trying to downplay the issue.

Dominion claims its systems are within industry standards, while ComEd outright disputes Whisker Labs’ findings. But here’s the problem, utilities often rely on outdated measurement tools that miss the granular, home-level data captured by Whisker Labs. So while utilities say everything is fine, residents are dealing with flickering lights, blown-out appliances, and rising repair bills.
