How much do you know about AI data center?

How much electricity does a single AI data center use in a year? The biggest ones use as much as 800,000 homes. One building.

Requests to connect new power projects to the grid now total over 700 gigawatts — more electricity than the entire United States consumed in 2023. This is the least glamorous corner of AI, and it has quietly become the part that decides who wins.

Why it changed so fast

The data centers that stored your photos and streamed your movies didn't draw much power. AI rewrote that. A modern AI server rack pulls 50 to 100 kW against 5 to 10 kW for a traditional one — roughly a tenfold jump in density. Anthropic has said training a single frontier model will soon need power on the scale of gigawatts.

So the logic in Silicon Valley collapsed to something simple: whoever can build the buildings and actually get them plugged in gets to train the bigger models. Data centers went from a back-office problem to the industry's hard limit.

The money is difficult to hold in your head

Morgan Stanley expects big tech to issue $250–300 billion in debt this year specifically to fund construction, and to spend roughly $3 trillion on AI infrastructure through 2028 — with company cash flow covering only about half. The rest is borrowed. Amazon alone spends over $100 billion a year; Google put in $90 billion in 2025.

Some of it is starting to look circular. A invests in B, B spends it on A's chips or cloud, and both revenue lines look wonderful while the same dollars go round a small circle — a pattern analysts say is raising eyebrows on Wall Street.

Bubble, or not enough?

BlackRock's Larry Fink, after a Davos session with Jensen Huang, came away thinking the real question isn't whether we're overspending but whether we're spending enough. The other camp remembers the fiber laid in 1999 for demand that arrived too late, and a Nasdaq that lost almost 80%. Parametrix's Jonathan Hatzor puts the risk not at weak demand but at overbuild against real demand, with a wave of boom-era projects landing over the next year.

Both can be right on different clocks. Short term, too much. Long term, if AI really does thread through every industry, nowhere near enough.

The bill nobody voted on

Your electricity may already cost more because of AI, even if you've never used it. PJM — the largest US grid operator, covering 65 million people across 13 states — has seen capacity auction prices jump more than 800% across two delivery years. In states thick with data centers, residential prices have climbed as much as 267% over five years.

The reason it's legal is mundane. US utilities are regulated monopolies, and big capital costs are recovered from the whole rate base — every customer splits the cost of new transmission and substations. That was fair when upgrades helped everyone about equally. It reads differently when one customer arrives wanting the power of a mid-sized city.

That fight is live. Twenty-four states have approved large-load tariffs making big new customers pay their own connection costs, with six more pending, and FERC has directed grid operators to guard against cost-shifting. Anthropic has said it will cover the electricity price increases its own data centers cause — the first major lab to volunteer for that bill.

Consent is the fourth scarce resource

In the first quarter of 2026, 75 projects worth $130 billion were delayed or blocked by community opposition, and 71% of people oppose one being built near them. It's the Amazon warehouse contradiction exactly: everyone wants next-day delivery, nobody wants the depot behind their fence.

So alongside chips, power and capital, there's a fourth scarce input — a town hall that doesn't organize against you.

Goldman expects global capacity to grow another 50% by 2027, to 92 gigawatts, while conceding the industry is running in a frenzied atmosphere. This probably doesn't end with a verdict on whether it was a bubble. It ends with a split: the cash-rich absorb the overbuild, the debt-funded don't.

And the race gets settled by three deeply unglamorous things — where the power comes from, where the water comes from, and whether the neighbors say yes.

If one were proposed down your road, would you vote yes?
