Google says it's doubling its use of the renewable energy that powers its data centers, offices, and other facilities, and plans to use renewable energy only by 2025.
Some of the clean energy will come from US sources -- North Carolina solar arrays and Oklahoma wind farms -- while some will be sourced from a wind farm in Sweden and a solar plant in Chile.
Once its imminent deals are settled, Google will consume over 2 gigawatts of clean energy. By 2025, it wants to use 3.6.
Google has spent about $2.5 billion on renewable energy to date. It says its commitment to going green is due in part to increasing demand for its key services.
