E squared -- The PBS series

e² is an ongoing PBS series that chronicles efforts in many countries to solve pressing ecological challenges. From energy consumption to design efficiency, policy to industry, the series documents the innovators whose work is reducing humans' impact on the environment. Interviews with experts, policymakers and pioneers across a variety of disciplines offer a firsthand account of the complex environmental challenges that we face, as well as the possibility that pragmatic solutions are within reach.

I just saw an episode that featured Mohamed Yunus' and Grameen efforts in small energy systems in Bangladesh.
