For those who are just returning from their weekend revelry, you all missed the launch of AutoblogGreen, Autoblog's first ever spin-off. AutoblogGreen was launched this past Saturday, the 36th annual celebration of Earth Day. It was a fitting launch for a blog covering every type of green car technology, green car culture and green car politics. Check out the site's first feature article that highlights a microbrewery in Cleveland using a big rig running on veggie oil to deliver beer. Stay tuned to AutoblogGreen to keep up on all things eco in the auto world.
