The evidence, explained
Power generation and cooling can affect air emissions, noise and nearby temperatures, but their impacts depend on equipment, operating hours, controls, distance and weather. Permit limits are not the same as actual emissions. Countywide air-quality classifications are pollutant-specific and should not substitute for a local exposure assessment.

A May 2026 study of four Phoenix-area data centers reported localized warming during a small set of field traverses, including average downwind–upwind temperature differences around 0.7–0.9°C and peaks around 2.2°C. This is useful evidence that waste heat can warrant investigation. It is not an El Paso measurement or a basis for drawing an identical impact radius around a proposed campus; the accessible institutional abstract does not permit a full independent review of its methods.

Useful local evidence would include permit applications and final conditions, operating-hour assumptions, baseline sound measurements, nearby sensitive locations and repeated monitoring under different weather conditions. Until those data are obtained and assessed, a categorical claim that impacts are negligible or severe would go beyond the evidence presented here.
Questions still worth asking
- Which permits and operating conditions apply to each site’s equipment?
- What baseline measurements exist near homes, schools and other sensitive locations?
- Who will monitor results over time and make the findings accessible?
