Amory Lovins on energy efficiency

These five videos show Amory Lovins, founder of the Rocky Mountain Institute, giving a lecture series on Advanced Energy Efficiency as the MAP/Ming Visiting Professor at Stanford University in 2007. The lectures are delivered in typical Amory style, peppered with numeric detail, filled with inspiring examples of green design, and bursting with information. I highly recommend watching all five if you have time. Higher quality versions are also available on iTunes.
