Accelerating the transition to a clean energy future
Across our operations, but especially at our datacenters, we are working to increase the amount of clean energy we use. We are committed to improving our energy mix, investing in new R&D to drive greater efficiencies and partnering with governments and utilities to create new clean energy projects. We believe that using more clean energy is good for our business, good for local communities where we operate and the environment. To date, Microsoft has directly purchased more than 500 megawatts of wind and solar energy in the U.S.
Wind energy purchases are an important part of meeting our commitment to renewable electricity.
Cheyenne Wind projects
In 2016, Microsoft announced our largest wind energy purchases yet — 237 megawatts of wind energy — that will allow our datacenter in Cheyenne, Wyoming to be powered entirely by wind power.
Keechi Wind project
In 2013, we signed a 20-year agreement to purchase 100 percent of the output of the 110-megawatt (MW) Keechi Wind project, a new wind farm that began operating in 2015.
Pilot Hill Wind project
In 2014, Microsoft purchased 175 megawatts of wind energy from the Pilot Hill Wind project in Illinois, which generates more than enough energy to power our Chicago data center and 70,000 Illinois homes.
In partnership with the Commonwealth of Virginia and Dominion Energy, we invested in a project that will bring 20 MW of new solar energy onto the grid in VA.
We generate a small amount of onsite renewable energy from solar panels covering the rooftops on our Silicon Valley campus.

In October 2015, Microsoft was named a Green Power Partner of the Year by the EPA for the third time in four years.
