A new Houston Advanced Research Center (HARC) report examines how Texas data-center growth could affect air pollution under different electricity scenarios.
In the projected power-mix scenario, nitrogen oxide emissions could rise by more than 135%; a more optimistic scenario puts them ten times lower.
HARC also notes that many proposed projects may never be built, so the scenarios should not be read as certain forecasts.
According to the report, if increased energy demand is met by the projected mix of sources, emissions of nitrogen oxides could increase by more than 135%, reaching levels not seen since 2004. Nitrogen oxides contribute to smog. Volatile organic compounds, another type of air pollutant, could exceed 2002 levels by more than 30%. Very small particles suspended in the air and sulfur dioxide could also increase, reaching levels seen in the early 2000s.
The report examines possible scenarios, not a firm prediction. HARC notes that many of the proposed projects may not actually happen. Developers could also combine renewable energy with grid power and use systems that capture carbon and reduce emissions of nitrogen oxides and volatile organic compounds. In a more optimistic scenario, nitrogen oxide emissions could be ten times lower.
However, according to the report, there is no scenario in which air pollutants do not increase, as the needs of data centers cannot be covered entirely by renewable sources.

Reducing vehicle emissions, using cleaner fuels, phasing out coal and reducing emissions from power plants have all helped improve air quality. HARC chief executive John Hall said there was a serious risk that future generations would be breathing more polluted air.
Meeting energy needs has led to the installation of mobile units that burn natural gas in data center sites. According to the report, their use circumvents environmental regulations and the obligation to report impacts. Protests have delayed data center projects, while temporary bans have been put in place in parts of the US.
