FWIW, from September of 2012:
Reuters) - U.S. Internet company Google Inc on Wednesday agreed to buy 48 megawatts (MW) of wind energy for its Oklahoma data center from the Canadian Hills wind power project in Oklahoma, which is expected to enter service later this year.
In a release, Google said it has been working with its local utility, the Grand River Dam Authority, to procure additional renewable energy since plugging in the Oklahoma data center in 2011.
In conjunction with the electricity the Grand River Dam Authority already supplies Google to operate its data center, Google said it would pay a premium to purchase renewable energy generated by Canadian Hills.
The Google data center is located in Mayes County about 170 miles northeast of Oklahoma City.
Google said the purchase brings the total amount of renewable energy it has contracted for to over 260 MW.
One megawatt can power about 1,000 homes.
Boston-based power generator Atlantic Power Corp owns 99 percent of the 298-MW Canadian Hills wind farm, which is located in El Reno about 30 miles west of Oklahoma City, according to Atlantic Power’s website.
Atlantic Power said it sells all of the power from Canadian Hills to three power companies: Southwestern Electric Power Authority, the Oklahoma Municipal Power Authority and Grand River Dam Authority.

MINCO, Okla. — Last year, Google consumed as much energy as the city of San Francisco. Next year, it said, all of that energy will come from wind farms and solar panels.
The online giant said on Tuesday that all of its data centers around the world will be entirely powered with renewable energy sources sometime next year.
This is not to say that Google computers will consume nothing but wind and solar power. Like almost any company, Google gets power from a power company, which operates an energy grid typically supplied by a number of sources, including hydroelectric dams, natural gas, coal and wind power.
What Google has done over the last decade, with relatively little fanfare, is participate in a number of large-scale deals with renewable producers, typically guaranteeing to buy the energy they produce with their wind turbines and solar cells. With those guarantees, wind companies can obtain bank financing to build more turbines.
The power created by the renewables is plugged into the utility grid, so that Google’s usage presents no net consumption of fossil fuels and the pool of electricity gets a relatively larger share of renewable sources.
“We are the largest corporate purchaser of renewable energy in the world,” said Joe Kava, Google’s senior vice president of technical infrastructure. “It’s good for the economy, good for business and good for our shareholders.”
Google hopes that success in working with large wind farms, like the 50,000-acre facility in Minco, Okla., which supplies Google’s large data center in Pryor, Okla., will spur development of the industry. NextEra Energy, which owns the wind farm, has about 115 wind farms in the United States and Canada.

Single-largest wind farm in North America
The 356 GE turbine-powered wind farm, which spans Blaine and Custer counties in north central Oklahoma, is one of the largest wind farms in the world.
Traverse is expected to generate 3.8 million megawatt-hours annually for American Electric Power’s Public Service Company of Oklahoma (PSO) and Southwestern Electric Power Company (SWEPCO) customers in Oklahoma, Arkansas, and Louisiana.
Traverse is the third and final wind farm that makes up the North Central Energy Facilities, which also includes the 199 MW Sundance and 287 MW Maverick wind farms, which began commercial operation in April and September 2021, respectively.
