The newly created initiative, known as RE<C, will focus initially on advanced solar thermal power, wind power technologies, enhanced geothermal systems and other potential breakthrough technologies.

RE<C is hiring engineers and energy experts to lead its research and development work, which will begin with a significant effort on solar thermal technology, and will also investigate enhanced geothermal systems and other areas.

In 2008, Google expects to spend tens of millions on research and development and related investments in renewable energy. The company also anticipates investing hundreds of millions of dollars in breakthrough renewable energy projects that generate positive returns.

Larry Page, Google co-founder and president of products, said: We have gained expertise in designing and building large-scale, energy-intensive facilities by building efficient data centers. We want to apply the same creativity and innovation to the challenge of generating renewable electricity at globally significant scale, and produce it cheaper than from coal.
