Data centers have become the latest flashpoint in America's technology wars, with communities nationwide pushing for moratoria on new facilities. But the opposition may be based on misconceptions about their actual impact on electricity costs and grid reliability. A 2026 study by researchers at the nonprofit Electric Power Research Institute (EPRI) found that data centers have pushed average U.S. retail electricity rates modestly down, not up, challenging one of the central claims made by opponents.

Are Data Centers Really Driving Up Your Electric Bill?

The EPRI researchers used an instrumental variables approach to isolate the causal effect of data center growth on retail electricity rates from 2015 to 2024. Their findings suggest that the economics of electricity generation work in data centers' favor: because power generation has high fixed costs, spreading those costs across more kilowatt-hours lowers the average price per unit. In other words, new demand from data centers helps utilities spread their infrastructure costs more efficiently.

The scale of data center electricity consumption is also smaller than many people realize. U.S. data centers consumed about 183 billion kilowatt-hours in 2023, roughly 4 percent of national electricity consumption. By comparison, air conditioning for homes and commercial buildings consumes about 425 billion kilowatt-hours annually, accounting for roughly 10 percent of all U.S. electricity consumption and 19 percent of power used in American homes. Yet no one proposes banning air conditioning.

The International Energy Agency projects that data center demand growth through 2030 will trail the added demand from electric vehicles and household electrification, suggesting data centers are just one contributor among many to rising electricity demand.

What's Driving the Data Center Backlash If Not Rising Bills?

The opposition to data centers follows a familiar pattern in technology debates. Historians have long noted that the 19th-century Luddites, often portrayed as anti-technology, were actually skilled workers opposing the consequences of innovation on their wages and working conditions, not the technology itself. The same dynamic plays out today with data centers, wind turbines, nuclear power, and other contested technologies.

One veteran organizer explained the strategic appeal plainly. Jane Kleeb, founder of the Bold Alliance, told Politico that data centers offer environmental groups a way to remain relevant: "After doing this work for 20 years, it is easier to mobilize communities to block something than it is to build something." This suggests the backlash reflects broader dynamics about how communities respond to rapid change, not necessarily empirical evidence that data centers harm consumers.

What Does the Future Hold for Data Center Demand and Grid Capacity?

While the EPRI study looked backward, the authors acknowledged that future dynamics could shift. If electricity supply fails to keep pace with demand, data centers could eventually contribute to higher consumer prices. A 2025 load growth report by Grid Strategies found that five-year peak-demand forecasts jumped sixfold in three years, to 166 gigawatts, with data centers driving roughly 55 percent of that growth.

The challenge is not data centers themselves but the mismatch between supply and demand. The U.S. electrical grid is currently ill-equipped to meet growing demand: the U.S. built fewer than 900 miles of high-capacity transmission in 2024 versus an estimated annual need near 5,000 miles. This supply-side constraint is the real problem, not the demand from data centers.

How to Evaluate Data Center Impact Claims

• Check the baseline: Data centers account for 4 percent of U.S. electricity consumption, smaller than air conditioning's 10 percent share, yet opposition focuses on data centers rather than cooling systems.
• Examine forecasting accuracy: Grid Strategies found that utility forecasts overstate data center load growth by around 40 percent because they fail to discount projects that never get built or never draw their full load.
• Assess grid management capacity: The North American Electric Reliability Corporation is writing rules for rapid load swings from large AI facilities, and Virginia's oversight agency found that existing utility processes limit reliability risks from rapid demand growth.

The key insight is that data centers have not raised rates to date, and whether they do in the future depends on whether regulators allow electricity supply to expand. The Joint Legislative Audit and Review Commission (JLARC), an oversight agency for Virginia, projected that a typical Dominion Energy residential customer could see costs climb by $14, but this outcome is not inevitable if supply-side solutions are pursued.

The data center debate ultimately reflects a deeper tension: communities can more easily block new demand than build new supply. But blocking data centers does not solve the underlying problem of rising electricity demand from electrification, heat pumps, and electric vehicles. The real policy question is whether regulators will invest in transmission infrastructure and generation capacity to meet demand, or whether opposition to data centers will simply shift the burden to other sectors.
