New social network/industry association for sustainable energy

I've been asked to serve as one of the (unpaid) members of the Advisory Board of a new site that launched August 1. Sustainable Energy Alliance - http://www.sustainea.com -- aims to bring together people and their organizations working on solar, biofuels, wind, geothermal, wave and any other alternative energy solution. The idea is that the industry associations charge too much (thousands of dollars) but you don't get quite enough from the free groups, such as those on linkedin.com. Check it out!
