A University of Houston Hobby School of Public Affairs survey of 2,000 likely Texas voters found that 79% support limiting the number of data centers that can be built across the state. The survey also found that 99% believe companies building data centers should pay for any electrical grid expansion needed to power them. The issue is growing on the campaign trail ahead of the November 3 election.

According to the survey, more than 80% of Texas voters are concerned about the potential effects of data centers on electricity prices, water supplies and power outages. About two-thirds said they are extremely or very concerned about those issues. Data centers house computer servers and related equipment used for artificial intelligence, cloud computing and digital services. They need large amounts of electricity and often use water for cooling.

Other findings: 76% believe a data center in their community would raise their electricity bills, and 61% believe nearby home values would fall. Also, 53% said they are extremely or very concerned about noise and air pollution. The survey reflects voters' expectations and concerns, not measured changes in utility bills or property values.
