Video blog from the S.F. Green Festival

Five times a year, people and companies devoted to the environment gather at the Green Festival in major U.S. cities. Yahoo! featured last year's San Francisco event in this blog, and we've reported on the Seattle version as well.

This year, Yahoo! had a booth featuring our green website. We encouraged visitors to share eco-friendly tips, and the results are in a slideshow here.

Want to get a look inside the festival? Check out this video -- you'll hear about home-energy audits, plug-in hybrid cars, and fair-trade chocolate, plus see how fun a green fest can be.
