on data centers and sustainability by taking a look at the role of green data centers in a future hazy with the inevitable impacts of climate change. Below, we take a step further by exploring the evolution of data center efficiency, as well as how the data center industry is looking to source renewable energy. Electricity is the lifeblood of any data center, which is why the industry consumes enormous amounts of power. The global data center industry used approximately 205 terawatt hours (TWh) in 2018, representing about 1% of the world’s electricity use that year, according to a paper by leading energy researchers.
