A WWF project to supply electricity to a remote island in the Sunderbans, a low lying area of the Ganges Delta in Eastern India, that is very vulnerable to sea level rise. Prior to this project the subsistence farmers had no access to electricity. The project involves charging large batteries from solar panels. Each villager collects a battery to run household lighting, and returns to the recharging station once a week to recharge their battery. This shot shows women carrying the heavy batteries (20Kg) from the charging station.

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.
