Along with the Iowa wind farm, Google's investment in clean energy now exceeds 990 million dollars.
The Internet search giant said it wants to use more renewable energy for its data centers and plans to have about one third of its data centers being powered by clean energy.
Google, based in Mountain View, California, created in June last year a 280-million-dollar fund with SolarCity, an American home solar energy designing and installing company, and the investment is said to be Google's largest of the kind in clean power to date. The search giant also pumped another 100 million dollars in the world's largest wind farm based in the U.S. state of Oregon in April last year, while unveiling a new plan in September to buy clean energy to directly power one of its data centers.
