Curious about the finer points of the clean energy grid? Looking for new ideas on campus low-impact farming or biomass plants? Just need to relax by watching students throw paint on each other in the name of art?

YouTube's new higher education site might have you covered. Already, more than 20,000 videos have been uploaded from universities like Wesleyan, Harvard, Dartmouth, UNC-Chapel Hill, Carnegie Mellon, the University of Minnesota and Virginia Tech. Topics cover everything from quantum physics to curing kleptomania, in a variety of formats, such as full-length lectures, short interviews, or webcam anecdotes.

The site offers to extend the reach of the university beyond traditional students, which sounds like a good idea to us, especially when it comes to keeping up with the latest research on renewable energy and sustainability. In fact, even though the site was only launched a few weeks ago, 85 results come up for the term 'clean energy,' and 'sustainability' pulls almost 300.
