Data centers consume about 70 billion kWh of electricity per year in the United States, close to 2% of the nation’s electricity use. Their demand continues to surge as the use of applications such as artificial intelligence, Internet of things, autonomous vehicles, and virtual reality grows. By improving energy efficiency, the Data Centers sector could save billions in both costs and kWh of energy.
