The Lincoln Institute reports that the number of U.S. data centers more than doubled between 2018 and 2021, then doubled again as AI investment accelerated [1]. It also reports that U.S. data centers consumed 176 terawatt-hours of electricity in 2023, roughly comparable to the electricity use of Ireland [
1].
Brookings says the United States accounted for about 45% of global data-center electricity consumption in 2024 [2]. Citing a U.S. Department of Energy and Lawrence Berkeley National Laboratory estimate, Brookings says data centers used about 4.4% of total U.S. electricity in 2023 and could rise to 6.7%–12.0% by 2028 [
2]. The International Energy Agency projects U.S. data-center electricity consumption will increase by around 240 TWh by 2030, up 130% from the 2024 level [
11].
Those figures change the local approval question. A proposed data center is not just another industrial building; it can be a major new power load with consequences for generation, transmission, substations, cooling water, and land use [1][

AI-era facilities are increasingly discussed in megawatts, not only in square feet. Consumer Reports describes a growing number of AI-driven hyperscale facilities that each use at least 50 MW of electricity, comparable to the demand of a small city [6]. Reuters reports that Big Tech’s AI race is running into U.S. grid constraints as electricity systems struggle to keep pace with hyperscale demand [

For host communities, the key question is not only whether a company can buy power. It is what generation, transmission, substation, or distribution upgrades may be needed; how long those upgrades will take; and whether costs could fall on the developer, the utility, ratepayers, taxpayers, or some mix of them [3][
6].
Data centers also need cooling, which can make AI growth a local water issue. The Lincoln Institute frames the AI data-center buildout as a land-and-water problem, and Consumer Reports identifies water use as one of the major public concerns surrounding AI data centers [1][
6].
A serious water review should go beyond a general assurance that supply is available. Local officials should ask for projected annual and peak water use, the water source, the cooling method, drought assumptions, wastewater handling, and any commitments to reuse or conservation [1][
6].
More data centers do not automatically mean dirtier air. The risk depends on how additional electricity is generated, how quickly cleaner resources and grid infrastructure are added, and what backup systems a facility uses [4][
6]. Reuters reported one example of the tension: AI-driven electricity demand was tied to a rollback of clean-air rules affecting St. Louis, a city already facing air-quality and health concerns [
4].
That makes air permits and backup-power plans part of data-center review, not side paperwork [4][
6]. Communities should understand what backup generation is planned, when it can run, what emissions limits apply, and whether additional power demand could affect local or regional pollution-control decisions [
4][
6].
Data centers can arrive as large campuses with long-term land commitments and related utility infrastructure. Consumer Reports says AI-driven hyperscale sites can sprawl across thousands of acres, while the Lincoln Institute emphasizes the land impacts of rapid data-center growth [1][
6].
Zoning reviews should address acreage, setbacks, stormwater management, transmission access, proximity to homes or farmland, and fit with existing land-use plans [1][
6]. Where relevant, local approvals should also set enforceable conditions for site design, construction impacts, and ongoing operations.
Consumer Reports frames AI data centers as a consumer issue because power demand can intersect with electric bills, water use, and other local impacts [6]. Reuters’ grid reporting points to the same governance problem from the utility side: demand can arrive faster than the grid is ready to serve it [
3].
A private power contract does not answer every public question. If a project requires new substations, transmission lines, distribution upgrades, or additional power resources, communities need clear terms on cost recovery and risk if demand forecasts change [3][
6]. If public incentives are being considered, officials should disclose the terms before approval, including fees, clawbacks, and any operating-data commitments.
Before approving a major AI data-center project, local officials should ask for public answers to seven questions:
The hidden cost of America’s AI data-center boom is not that computing has no value. It is that AI’s infrastructure footprint is concentrated locally while the digital services it supports can be used far beyond host communities [1][
2][
3][
6].
National estimates are useful, but they are not enough. Impacts vary by project size, cooling design, water source, grid condition, backup systems, and local regulation [1][
3][
4][
6]. No major data-center approval should move forward without public, project-specific numbers on electricity, water, emissions, land impacts, incentives, and who pays.

China and the United States are the most significant regions for data centre electricity consumption growth, accounting for nearly 80% of global growth to 2030. Consumption increases by around 240 TWh (up 130%) in the United States, compared to the 2024 lev...
