Google will purchase an extra 100.8 megawatts of wind power from NextEra to power its data centers as part of a huge green push the company has made in the past month.

The wind farm should be completed later this year thanks to a direct commitment from Google Energy. The new wind farm follows Google’s 114-megawatt purchase from an Iowa wind farm last year. In 2007, the company pledged to become carbon neutral and has made several pushes to improve the efficiency of its buildings and fund clean energy projects.

Google has invested $350 million in renewable energy projects to date. The majority are philanthropic and don’t serve as strategic investments for the search engine giant.

The company recently invested $168 million in a solar thermal power project in California, which uses mirrors to focus sunlight that heat water and powers a conventional steam turbine. Google also invested $5 million in a German solar power plant in its first clean tech investment outside of the United States.

On Monday, Google announced that it would invest $100 million in a wind power farm in the Shepherds Flat Wind Farm in  Oregon. When completed, that wind farm will generate up to 845 megawatts of power, or enough to power more than 200,000 homes. The electricity produced at that wind farm will be sold to Southern California Edison.

NextEra has more than 9,500 wind turbines across 85 wind farms in the U.S. Its wind farms appear in 17 states in the U.S. and also in Canada, and generate enough power to provide energy for more than 2 million homes each year.
