US Heat Waves Trigger Concerns about Data Center Energy Consumption

A severe heatwave stretching across much of the U.S. is placing extraordinary pressure on electricity networks and water resources, intensifying concerns about the country’s accelerating construction of artificial intelligence data centers.

The current spell of extreme weather arrives as the U.S. invests heavily in thousands of new facilities designed to power advanced AI systems. However, policymakers, utility companies, and regulators have repeatedly warned that the rapid pace of development is exceeding upgrades to water systems and electrical grids.

Lawmakers are increasingly questioning the growth of these facilities. During a campaign appearance this week, Texas Gov. Greg Abbott proposed prohibiting new data centers in rural communities. He has also argued previously that operators should produce their own electricity and adopt water recycling systems instead of relying on local supplies.

Sen. Bernie Sanders and Rep. Alexandria Ocasio-Cortez have each supported suspending approval of additional data center projects until their environmental impact can be more thoroughly assessed.

Public opinion appears to reflect this growing skepticism. A recent Gallup poll found that roughly 70% of Americans oppose building data centers near where they live. Among those respondents, many pointed to heavy consumption of water and electricity as their biggest concern.

The U.S. Energy Department estimates these facilities currently account for about 4% of national electricity demand. That figure is projected to climb to approximately 9% before the end of the decade.

Experts say the ongoing heatwave highlights weaknesses in infrastructure that was built for far milder conditions. According to Arif Gasilov of the Gasilov Group, rising global temperatures are exposing the limitations of existing cooling systems, which were never intended for increasingly frequent periods of extreme heat.

Grid operators are already responding. PJM Interconnection, which oversees electricity transmission across 13 states and Washington, DC, has asked the Energy Department to require major data centers to activate backup generators during emergencies. Officials believe the measure would free additional electricity for homes and businesses while temperatures remain dangerously high.

The eastern U.S. has been particularly affected, with heat index values exceeding 100°F in cities including Washington and New York. Record-breaking temperatures have also been forecast for Central Park.

Data centers are concentrated mainly across the Midwest and the South, while research from Pew shows that 38% of Americans live near one of the country’s approximately 3,000 operating facilities. During hotter weather, cooling systems consume even more electricity than usual, adding further strain to already stressed grids.

Scientists have also linked these sites to localized warming. Research from the University of Cambridge found surrounding temperatures can rise by an average of 3.6°F, with much higher increases immediately adjacent to large installations.

The challenges extend beyond electricity. Many cooling systems depend heavily on fresh water, and most lose significant amounts through evaporation rather than reuse. Although overall water consumption remains lower than agriculture, manufacturing, or residential demand, experts warn AI growth will steadily increase pressure, particularly in drought-prone regions.

Nearly two-thirds of new developments since 2022 have been planned in areas already experiencing water scarcity.

Large AI facilities can consume up to five million gallons of water each day, with demand peaking during the hottest periods when local communities often face restrictions. Analysts caution that without significant improvements in efficiency and infrastructure, expanding AI capacity could deepen competition for essential resources in the years ahead.

The concerns about data centers highlight the irony of how many people and companies like GlobalTech Corp. (OTC: GLTK) now depend on this technology on a daily basis but communities are unwilling to host these facilities due to concerns about their electricity and water use.
