Is AI guzzling all our electricity?
AI's electricity use is real and growing fast, but it's still a small slice of the whole: all U.S. data centers used less power in 2024 than American home air conditioning. The fight worth having is over who pays for the buildout and what powers it, not whether the grid can survive.
01What you’ve heard
The growth is real, and parts of this are worth worrying about. But the “AI is breaking the grid” headline gets the scale wrong, and points the alarm at the wrong target.
02What’s actually true
Data centers are a real and fast-growing load. They are not, at the national scale, an outlier.
Here is the comparison that resets the conversation. In 2024, every data center in the country combined used less electricity than Americans running their home air conditioners.
Worldwide it’s a smaller slice still: data centers use just over 1% of global electricity.3 And while that number is climbing, data centers are only about 8% of the growth in global electricity demand expected this decade, behind both electric vehicles and air conditioning.3
The per-question scare doesn’t hold up either. A typical ChatGPT query uses about 0.3 watt-hours, roughly what an LED bulb or a laptop draws in a few minutes, not the viral figure that was an order of magnitude higher.4
03Where the real concern is
Here’s what the “grid apocalypse” framing buries: the legitimate fight isn’t about the national total. It’s about who pays for the buildout, and what gets burned to power it. Both are going the wrong way, and both are fixable.
On cost, the grid operator for 65 million people across the mid-Atlantic and Midwest just ran the most expensive capacity auction in its history, and its own independent market monitor put data centers at the center of it.
Researchers at Harvard’s Electricity Law Initiative reviewed nearly 50 regulatory proceedings and found utilities are increasingly shifting the cost of serving data centers onto everyday ratepayers; in Virginia, that could mean $150 to $450 more per household per year by 2040 under current rules.6
And what powers all of it is sliding backward. Utilities have delayed the retirement of at least 15 coal plants, partly to serve projected data-center demand,7 and in Memphis, xAI ran dozens of gas turbines next to a predominantly Black neighborhood that already carries some of the state’s worst asthma rates, before securing the usual air permits.8 That is the real cost, and it lands on specific communities.
Talking points — ready to paste
- All U.S. data centers used less electricity in 2024 than American home air conditioning.
- Data centers are about 8% of the growth in global electricity demand this decade, behind EVs and air conditioning.
- A typical ChatGPT query uses about 0.3 watt-hours, roughly an LED bulb for a couple of minutes.
- The real AI energy fight isn't whether the grid can cope. It's who pays for the buildout and what powers it.
04The progressive move
Don’t fight the data center. Fight the bad deal. Make Big Tech, not families, pay for the grid upgrades its facilities require, through cost-causation rate design and the kind of rules Virginia and federal regulators are now testing. Tie the buildout to clean firm power; the wave of nuclear and geothermal deals shows it can be done, and push for around-the-clock clean matching instead of paper credits. And block the fossil lock-in, especially where it dumps pollution on the communities least able to fight back. The grid can handle AI. The question is who pays for it, and whether it runs clean.
