Google announces massive clean energy purchase

Google today announced it will purchase 842 megawatts of clean energy, nearly a doubling of the power it's purchased to date and taking the company to 2 gigawatts of clean energy.
Google's announcement comes on the heels of a historic multi-national agreement at the United Nations Climate Summit in Paris to double R&D investments in clean energy.
On Monday, President Obama and Bill Gates announced that the U.S. is joining 19 other countries and 28 technology innovators to double funding and other resources for clean energy research and development.
