The announcement that Google plans to branch of into Renewable Energy is telling of how times are changing. The world's biggest problems do ultimately attract among the world's best innovators. According to Larry Page, co-founder of Google "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." Google's goal is to produce one gigawatt of renewable energy capacity that is cheaper than coal.
How? By focussing initially on advanced solar thermal power, wind power technologies, enhanced geothermal systems and "other potential breakthrough technologies."
This is another very important indication that the world's biggest environmental crises may turn into a booming industry. It is also a clear indication that the IT boom of the last couple of years has reach a stage of maturity and new growth areas are sought.
