POTD: Sustainable Energy

From 2016 02 07 Ranthambore

Today's photo-of-the-day is from Rajasthan, India, where not much goes to waste. The disks stacked on this house's roof are made of cow dung and are used as fuel. I'm not sure whether burning coal or burning cow dung is worse for the environment, but cow dung is cheap, efficient, and sustainable. It's also photogenic, at least for this tourist.
