Data Centers' Energy Hunger Threatens Climate Goals as US Turns Back to Fossil Fuels

Data Centers' Energy Hunger Threatens Climate Goals as US Turns Back to Fossil Fuels

The exponential growth of artificial intelligence and data processing is creating an unprecedented energy crisis in the United States, forcing grid operators to abandon renewable energy commitments and resurrect aging fossil fuel plants. Current data centers consume electricity equivalent to powering 100,000 households, yet future facilities under construction will demand 20 times that amount.

As demand for computing power surges, energy companies and policymakers are increasingly choosing quick, cost-effective fossil fuel solutions over long-term climate investments, fundamentally reshaping the nation's energy infrastructure and environmental trajectory.

The Energy Crisis Deepens

The United States hosts more data centers than any other nation globally, and the resulting strain on electrical transmission networks is pushing grid operators toward polluting energy sources. PJM Interconnection, which serves 13 eastern states including Virginia—the world's "data center capital"—postponed or canceled the closure of 60% of its fossil fuel plants last year. Among these were 11 "peaker" plants designed to activate during periods of peak electricity demand.

"It is clear today, nationally, that electricity demand is outstripping supply — the market reflects this, and generators are responding," stated Jeff Shields, a spokesman for PJM Interconnection, speaking to Reuters. "We need every single megawatt of energy we can get right now."

Renewable Commitments Abandoned

Major energy providers are shelving their climate pledges in favor of fossil fuel expansion. Dominion Energy, based in Virginia, had committed to achieving 100% renewable energy by 2045 but now plans substantial investments in gas and nuclear power through 2039 to ensure reliable electricity supply.

Similar reversals are happening across the country:

• NV Energy in Nevada warned that data centers could prevent the state from reaching its 50% clean energy target by 2030
• NextEra Energy announced in December that achieving zero-carbon emissions by 2045 is no longer feasible, given North Carolina's nearly 100 operating data centers

Natural Gas: The Path of Least Resistance

According to the International Energy Agency, natural gas provides over 40% of electricity for US data centers, while coal supplies 15%. Dave Jones, chief analyst at energy research organization Ember, explained the industry's preference for gas: "The quickest, cheapest, easiest way in the eyes of many companies is to use gas."

The appeal is particularly strong given that US natural gas prices have reached 18-month lows, making the fuel economically attractive compared to renewable alternatives. The IEA projects that natural gas and coal will power over 40% of additional data center electricity through at least 2030, with these sources likely becoming "a significant near-term driver of growth" for fossil fuel generation.

Political Climate Shifts Course

The Trump administration's return to office has accelerated the shift away from clean energy policies. Energy Secretary Chris Wright reframed climate action as merely one consideration among many, stating: "How are we going to reindustrialize America? How are we going to win the AI race? Climate change, like every other issue, is a trade-off."

The administration has signed executive orders favoring fossil fuels and emphasized coal and nuclear energy's importance for sustaining US power needs. Jones noted that many previous commitments by AI companies to use clean electricity "have gone out the window."

"The other component of all of this is just that there's absolutely zero desire for any climate responsibility," said Jones, commenting on the policy shifts under Trump.

Renewable Energy Still Growing Globally

Despite domestic setbacks, renewable energy supplies nearly 27% of electricity for more than 4,200 US data centers, particularly in sun-rich regions of the south and southwest. Globally, the IEA projects that renewables and natural gas will account for over 65% of all data center electricity by 2030, with substantial growth expected in Southeast Asia.

In regions like India and China, where coal and renewables currently provide a mixed energy portfolio, analyst Jones suggested that rising fossil fuel prices from Middle East tensions could prompt countries to prioritize renewable and nuclear investments for their expanding data center networks.

Public Resistance Mounts

Americans are increasingly opposing data center expansion in their communities. A Quinnipiac University poll found 65% of residents opposed facilities near their homes, with nearly two-thirds citing concerns about rising electricity costs.

This opposition is producing results: In New Jersey, where average electricity bills jumped 17% last year, residents successfully blocked a planned data center. Maine legislators backed legislation to pause new construction until November 2027 to assess risks to power grids and the environment.

"If these centers aren't thoughtfully planned and coordinated, they can place extraordinary demands on electric infrastructure, the surrounding environment and host communities," warned Maine state Representative Melanie Sachs.
