AI Data Centers Push Power Demand to the Fastest Growth in Decades

I’m sure you’ve noticed, but families are paying record or near-record amounts just to keep cool this summer.

According to the Bureau of Labor Statistics, electricity costs have climbed 5.5% in the past 12 months, while natural gas prices have jumped nearly 14%. The National Energy Assistance Directors Association (NEADA) says the average household will spend nearly $800 on summer cooling alone, the highest level in more than a decade.

Past performance does not guarantee future results.

When costs rise this quickly, people naturally look for someone—or something—to blame. President Donald Trump, never one to mince words, took to Truth Social to point the finger at “STUPID AND UGLY WINDMILLS,” which he claims are driving up energy prices in New Jersey and across the country. Many of you may have seen his posts.

There’s some truth in what the President is saying. Energy is political, and the rush to “green” policies has often been ham-handed and expensive.

But in this case, the facts tell a more complicated story. The truth is that offshore wind projects off the Jersey Shore never even got built. Today, renewables make up only about 8% of New Jersey’s electricity, and wind contributes less than 1%.

That means the culprit behind higher electricity bills isn’t wind turbines. Instead, it’s a surge in demand exacerbated by an aging grid, higher natural gas costs and the billions of dollars utilities are investing to modernize their infrastructure.

America’s Electricity Demand Is Rising at the Fastest Pace in Decades

For nearly two decades, U.S. electricity demand was flat. Between 2005 and 2020, consumption barely budged, thanks to efficiency gains in appliances and slower economic growth. Utilities planned for more of the same.

But the past three years have challenged those assumptions. Nationwide demand is now growing 2% to 3% annually, according to the Energy Information Administration (EIA). In Texas and the Mid-Atlantic, where data centers and manufacturing plants are sprouting like weeds, demand is rising 10% or more per year. This July, America broke its electricity demand record twice in two days, hitting nearly 760 gigawatts at peak—enough to power every home in Texas 60 times over.

Utilities Are Investing Record Sums to Strengthen the Grid

The AI boom is a major driver. Data centers consumed around 180 terawatt-hours of power last year, and that number could double before the decade is out. Add in the electrification of vehicles, reshoring of factories and hotter summers, and demand is rising faster than utilities can keep up.

The Edison Electric Institute (EEI), which represents America’s investor-owned utilities, reports that the industry poured a record $178 billion into the grid last year. That’s the 13th straight year of record spending. Over the next five years, capital expenditure is projected to exceed $1.1 trillion.

Past performance does not guarantee future results.

Global Renewable Generation Has Surged Past 40%

Even as Trump rails against wind and solar, the economics have never looked stronger. Lazard’s latest Levelized Cost of Energy (LCOE) study shows that, without subsidies, renewables remain the cheapest source of new electricity generation. Utility-scale solar in the U.S. can now deliver electricity at about $0.04 per kilowatt-hour—less than half the cost of new coal or gas peaker plants.

Past performance does not guarantee future results.

Globally, renewables already make up over 40% of generation, with solar the fastest-growing source of electricity for the 20th year in a row. In the U.S., developers plan to add 64 gigawatts of new capacity this year alone—more than half of it solar, with the balance in batteries, wind and natural gas. That’s the largest annual buildout since 2002, when gas was king.

Private equity firms see the writing on the wall. BloombergNEF reports that most of their new energy investments are in renewables, not fossil fuels. Ten years ago, solar power was four times more expensive than fossil fuel. Today, it’s more than 50% cheaper.

Renewables Are Cushioning Consumers from Volatile Gas Prices

This doesn’t mean renewables are flawless. They require transmission buildout, storage and backup. But the claim that “windmills are causing high prices” just doesn’t hold up to the numbers. If anything, renewables are helping cushion the blow from volatile gas markets.

None of this is much comfort when you’re opening a $500 electric bill. But it’s worth taking the long view. Today, the biggest line item in the American household “energy wallet” isn’t electricity; it’s actually gasoline, which costs families nearly $3,000 per year on average, according to a report by the Electric Power Research Institute (EPRI). But as vehicles go electric, those dollars will shift from gas pumps to utility bills.

The EPRI additionally projects that by 2050, household energy spending could fall by more than a third in real terms because we’ll spend less on gasoline and heating oil.

Ignore the Politics, Follow the Money

So, what’s the takeaway for investors?

Utilities have historically been seen as “boring” dividend payers, but today, I see them becoming beneficiaries of the same AI and industrial growth trends that have propelled chipmakers and robotics firms. Last year, a staggering 94% of utilities raised or reinstated their dividends, with payout ratios higher than any other U.S. sector, according to the EEI.

I say ignore the politics and follow the money. Solar and wind are not only cheaper—they’re where developers, private equity and global capital appear to be placing their bets.

With demand surging, utilities are modernizing. Renewables are the cheapest way forward.
