"In total, the report says, U.S. data centers used 91 billion kilowatt-hours of electricity last year, "enough to power all of New York City's households twice over and growing."

By 2020, annual data center energy consumption is expected to reach 140 billion kilowatt-hours."

I wonder how much of that usage is for cooling and how much is for powering the computers?
