Disclosure: I'm a writer for Gas 2.0, so I'm biased.
Before I was a writer for the blog, I read it regularly. I do believe the blog is the best source for information on the future of transportation the world over. We try our best to dig up the interesting tidbits that can get lost in the daily information overload. We pride ourselves on making topics understandable and balanced. Please check it out and make it a part of your daily internet habit.
I visit Gas 2.0 almost every day for news updates on alternative fuel technologies. They do a particularly good job of covering biofuels news, but also do a lot of electric vehicle coverage. It's a very informative and well-run site, part of the Green Options network. Plus I'm about to become a blogger for the site, so that makes it super awesome!
