"Innovation in green tech could be the biggest economic opportunity of the 21st century." So says John Doerr of Kleiner Perkins Caufield & Byers the venture capital firm responsible for initial funding of Google, Amazon.com and Sun Microsystems. We couldn't agree more.

To prove the point the firm has created an annual contest with a grand prize of $100,000. The "KPCB Prize for Green Innovation" will recognize entrepreneurs whose creativity and dedication result in substantial advancements in green technology.

Applications will be accepted until October 31, 2006 and can be submitted by any person, group, organization, or company creating significant, sustainable innovation in green technology. Describe your breakthrough idea in 5 pages or less and email it to This email address is being protected from spam bots, you need Javascript enabled to view it . The winner will be announced during the 2nd Greentech Innovation Network (GIN) Conference in December.

If you've got an idea that could qualify in the field of green energy generation, storage, conservation, policy, or  other green/clean technology, you've got until the end of the month to submit.
