Got a clean tech business plan? Google may have your number. The Internet behemoth is becoming increasingly interested in investing in clean tech businesses. Reports the New York Times:

"Google is now considering large investments in projects that generate electricity from renewable sources."

While Google's philanthropic arm has made investments in companies that, for instance, use kites to harness wind power, company execs are suggesting that they may not only up their investment, but expand into other areas of clean energy. As evidence, the New York Times reports, the company has hired a number of experts in the field of renewable energy, including scientists, ex-government energy officials, and even an ex-NASA astronaut. They will explore the possibility of not only developing clean technology in house, but will advise any potential investments that Google makes. And given that Google has more than $14.5 billion sitting around, things may start looking good for start-ups with strong clean technology business plans.
