ease11A study published by Berkeley National Laboratory indicates United States data center energy consumption could reach an its lowest levels since 2003 within the next five years.

Data center energy consumption has been a popular industry topic within the past decade. Between 2000 and 2005, national data center energy consumption skyrocketed by 90 percent, and continued to grow another 24 percent by 2010. This amount of power consumption initiated discussions and developments from both tech industry leaders and environmental groups to create more efficient data center technologies.

In light of efficiency development power consumption only grew 4 percent between 2010 and 2014. The study projects energy consumption will only grow an additional 4 percent by 2020, but with the right efficiency measures, consumption could drop as much as 45 percent.

While these developments are a positive outlook for the industry, the 45 percent drop is not guaranteed. Data centers still require mass amounts of electricity to function to their best ability, and accounted for 1.8 percent of all U.S. electricity consumption in 2014.
