Women constructing solar cookers at the Barefoot College in Tilonia, Rajasthan, India. The Barefoot College is a worldwide charity, founded by Bunker Roy, its aims are, education, drinking water, electrification through solar power, skill development, health, women empowerment and the upliftment of rural people. The use of the cookers, vastly reduces the amount of fire wood women have to go out and collect from the forest.

The Muni Seva Ashram in Goraj, near Vadodara, India, is a tranquil haven of humanitarian care. The Ashram is hugely sustainable, next year it will be completely carbon neutral. Its first solar panels were installed in 1984, long before climate change was on anyones agenda. Their energy is provided from solar panels, and wood grown on the estate. Waste food and animal manure is turned inot biogas to run the estates cars and also used for cooking. Solar cookers are also used, and the air conditioning for the hospital is solar run. 70 % of the food used is grown on the estate. They provide an orphanage, schools for all ages, vocational training, care for the elderly, a specialist cancer hospital withstate of the art machinary, and even have a solar crematorium. This shot shows a cook preparing chapatis on a biofuel stove.
