Sen. Elizabeth Warren (D-MA) said she has opened an investigation into AI data centers.
“A single AI data center uses as much electricity as 100,000 households—and utility companies are passing the upgrade costs to you, not to the trillion-dollar tech giants,” Warren said.
“I’ve opened an investigation. These companies need to pay their costs,” she added.

“U.S. Senators Elizabeth Warren (D-Mass.), Chris Van Hollen (D-Md.), and Richard Blumenthal (D-Conn.) opened an investigation into the extent to which big tech data centers are driving up consumers’ electricity costs. The senators sent letters to Google, Microsoft, Amazon, Meta, CoreWeave, Digital Realty, and Equinix,” Warren’s office stated in a press release last December.
“We write in light of alarming reports that tech companies are passing on the costs of building and operating their data centers to ordinary Americans as AI data centers’ energy usage has caused residential electricity bills to skyrocket in nearby communities,” the lawmakers wrote.
“Through these utility price increases, American families bankroll the electricity costs of trillion-dollar tech companies,” they continued.
“Big tech companies are building massive, energy-guzzling data centers to power their AI models. And rather than paying for the cost of new infrastructure to accommodate those data centers, some of the richest companies are passing those costs onto you. You shouldn’t be subsidizing AI data centers,” Warren said last week.

More from the press release:
As American AI companies build new models, their AI data centers require more and more energy from the grid. A single data center uses enough electricity to power hundreds of thousands of homes, and the U.S. Department of Energy projects that data centers could make up 12% of all U.S. power consumption by 2028.
As a result, utility companies have spent billions of dollars updating the electrical grid to accommodate the data centers’ unprecedented energy demands, including building expensive new transmission lines and power plants. These infrastructure buildouts cost billions of dollars: the utility Indiana Michigan Power estimates that building new power plants to meet data center demand in the region will cost $17 billion over the next several years. These costs appear to be recouped by raising residential utility bills, meaning American consumers could end up subsidizing the energy demands of Big Tech. Since President Trump took office, household electric bills have gone up 13% nationally.
“Recent increases to consumers’ utility bills are directly linked to the tech industry’s data center buildout,” wrote the lawmakers. “When utilities expand their grid infrastructure, they incorporate the cost of expansion into their utility rates, passing the extra costs onto their customers.”
The contracts between data centers and utility companies are almost always confidential, leaving the public in the dark on why their electric bill keeps going up. That’s why the senators are pushing for answers from these companies and asking them what they intend to do to mitigate these cost concerns.
“Tech companies have paid lip service in support of covering their data centers’ energy costs, but their actions have shown the opposite… And on top of failing to pay their fair share of their electricity rates, tech companies regularly hide as much information as possible from the communities in which their data centers will be built,” continued the lawmakers. “To protect consumers, data centers must pay a greater share of the costs upfront for future energy usage and updates to the electrical grid provided specifically to accommodate data centers’ energy needs.”
In March, Sen. Bernie Sanders (I-VT) and Rep. Alexandria Ocasio-Cortez (D-NY) introduced legislation to enact a moratorium on the development of AI data centers.

“Sanders and AOC introduced a bill to pause ALL AI data center construction. 300+ local bills filed. Half of planned 2026 data centers facing delays or cancellation. Each one brings billions to local economies. The people who say they want American jobs are trying to block the biggest job creation engine since the interstate highway system,” venture capitalist and Y Combinator Garry Tan said.
Tan’s comment sparked a reaction from Elon Musk.

The debate centers on whether infrastructure costs tied to AI growth are being fairly distributed.
Critics argue households are indirectly subsidizing Big Tech expansion, while companies say they pay their own energy costs and operate under regulated utility agreements.
An Amazon spokesperson previously said, “Amazon pays for its own electricity costs,” adding that independent research “failed to find evidence that residents are subsidizing our data centers.”
Data centers account for about 5% of U.S. electricity use, a share expected to rise as AI grows. McKinsey & Co. projects this could more than double in five years, with data centers driving up to 40% of new electricity demand by 2030.
