Google announced today that it's throwing $55 million dollars to the wind... energy, that is. A post to the official Google blog said the company has invested the aforementioned amount in the Alta Wind Energy Center, which is set to generate 1,550 megawatts of energy -- enough to reportedly power 450,000 homes -- from a batch of turbines in the Mojave Dessert. Developed by Terra-Gen Power, the operation will carry the resulting energy via transmission lines to "major population centers." The ever-humble internet giant pointed out that this particular injection of funds marks a total investment of $400 million in the clean energy sector. In fact, El Goog signed a deal last year to power several of its data centers with wind power, and most recently announced the opening of a seawater-cooled data center in Finland.
