Apple has bought a 30% stake of Goldwind, based in China, for wind energy that will produce 285 megawatts of power. Apple invested in four subsidiaries located in different provinces where the power will come from: Henan, Shandong, Shanxi, and Yunnan provinces in China.

Goldwind, one of the largest wind turbine makers based in Xinjian, made the announcement last week. Lisa Jackson, Apple’s vice president of environmental initiatives, told local chinese media that the investments in wind turbines will collectively yield 285 megawatts of clean energy. The company hopes to direct the power toward manufacturers connected to Apple’s supply chain.

Apple has been progressively moving towards alternative forms of energy by heavily investing in solar and wind. Apple previously invested in a 40 megawatt solar power project in Sichuan, including three other solar projects to generate 170 megawatts of power.
