Energy Demand Crisis: Can Data Centers Transition to Clean Power?

Energy Demand Crisis: Can Data Centers Transition to Clean Power?

The explosive growth of artificial intelligence and digital infrastructure is forcing the United States to rely increasingly on fossil fuels to power data centers, threatening previously established climate commitments. Grid operators across the country are postponing closures of coal and gas plants and reconsidering nuclear energy options as electricity demand surges beyond current supply capacity.

Massive Energy Consumption Strains Infrastructure

Modern data centers consume extraordinary amounts of electricity to operate servers and maintain the digital systems that support websites, applications, and generative AI models. Individual artificial intelligence data centers today can demand as much power as 100,000 households, while the largest facilities under construction will require twenty times that amount.

The United States hosts more data centers than any other nation globally, and this concentration has created unprecedented strain on regional electrical grids. According to recent Reuters analysis, PJM Interconnection—the nation's largest power grid serving thirteen eastern states including Virginia, known as the "data center capital of the world"—postponed or canceled planned closures of 60% of its fossil fuel plants last year. Among these were eleven 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," PJM Interconnection spokesman Jeff Shields stated. "We need every single megawatt of energy we can get right now."

Climate Pledges Abandoned for Energy Security

Major energy providers have begun deprioritizing environmental objectives to meet immediate power needs. Virginia-based Dominion Energy, which had committed to achieving 100% renewable electricity sources by 2045, has now planned substantial investments in gas and nuclear capacity through 2039 to ensure reliable power generation when demand peaks.

Similar reversals have occurred nationwide. NV Energy in Nevada warned that data center expansion could prevent the state from reaching its goal of generating 50% renewable electricity by 2030. In North Carolina, which hosts nearly 100 data centers, NextEra Energy announced in December that it no longer viewed achieving zero-carbon emissions by 2045 as feasible.

Natural Gas Becomes Preferred Solution

Dave Jones, chief analyst at energy research organization Ember, explained that the unpredictable electricity requirements of data centers have made fossil fuels—particularly natural gas—the most attractive short-term solution. Natural gas currently provides more than 40% of electricity for US data centers, while coal-fired plants supply 15%, according to the International Energy Agency.

"The quickest, cheapest, easiest way in the eyes of many companies is to use gas," Jones noted. Current low natural gas prices—at eighteen-month lows—have reinforced this preference among operators making rapid infrastructure decisions.

The International Energy Agency projects that natural gas and coal will together power over 40% of the additional electricity needed by data centers through at least 2030, with demand from planned facilities creating "a significant near-term driver of growth for natural gas-fired and coal-fired generation."

Policy Shifts Remove Climate Barriers

The transition away from renewable energy has been accelerated by policy changes under President Donald Trump's administration. Jones noted that numerous climate commitments made by artificial intelligence companies regarding clean electricity use for their facilities have "gone out the window."

Trump has signed executive orders promoting fossil fuel expansion, and the Department of Energy has emphasized the importance of coal and nuclear for sustaining US energy requirements, particularly regarding data center growth and artificial intelligence development. Energy Secretary Chris Wright characterized climate considerations as a "trade-off" when addressing national reindustrialization and competitive advantages in artificial intelligence competition.

Import tariffs on solar panels and renewable technologies from abroad have further slowed clean energy expansion for data center operations.

Alternative Solutions Exist

Clean energy advocates counter that technological alternatives can meet increased power demands without expanding fossil fuel infrastructure. Grid transmission improvements and battery storage systems, they argue, could replicate the backup capacity provided by peaker plants while eliminating associated air pollution.

Renewable sources currently power approximately 27% of electricity for the more than 4,200 US data centers, particularly in sun-rich southern and southwestern regions. Globally, the International Energy Agency projects that renewables and natural gas will combine to generate over 65% of all data center electricity by 2030, including in Southeast Asian markets where electricity demand from data centers is expected to more than double during this period.

Community Resistance Grows

Public opposition to data center expansion is intensifying. A Quinnipiac University poll found that 65% of Americans oppose having a data center facility near their residence, with nearly two-thirds citing electricity cost concerns.

In New Jersey, where average electricity bills increased approximately 17% last year, residents in one municipality successfully prevented a planned data center development through environmental and energy concerns. Maine legislators have backed legislation that would suspend new data center construction until November 2027 to assess potential impacts on electrical infrastructure 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," stated Maine state Representative Melanie Sachs.
