Serious Growth in Data Center Energy Requirements Data centers in the U.S. consume over 62 billion kwh annually. Annual energy cost exceeds 4.5 billion dollars. Ifcurrent trends continue that usagecould double by 2012. Data centers consume 30 times more power per square foot than a standard office building.
Energy Use Expected to Double This could leadto Increased energy costs for business and government Increased emissions, including greenhouse gases, from electricity generation Increased strain on the existing power grid to meet the increased electricity demand, resulting in: Blackouts Brownouts Rolling Blackouts Increased capital costs for expansion of data center Increased capital costs for expansion of data center capacity and construction of new data centers.
