Google is going green—green enough to offset its entire nonrenewable energy consumption.

The company announced Thursday that it had purchased enough wind and solar energy to match 100 percent of the energy required to run its products in 2017. The clean energy purchases brought the company’s total wind and solar capacity to over three gigawatts.

“With solar and wind declining dramatically in cost and propelling significant employment growth, the transition to clean energy is driving unprecedented economic opportunity and doing so faster than we ever anticipated,” Gary Demasi, Google’s director of global infrastructure, said in a statement.
