Sustainable electricity in rural India

Rocketboom, one of my favorite vlogs, did an interview with the founders of the Barefoot Foundation a few days ago. This is a great piece about bringing sustainable energy to villages in India. The Barefoot Foundation seems to take a microfinance-style approach, similar to that of the Grameen Foundation, of training a lady from a village to perform a service for the village, and thereby becoming a village leader.
