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 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. Solar cookers save women having to walk to the froest to cut down wood for cooking, thus saving the forests, and a daily chore for woman.

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.

Orkney Islands Sept 2011 Wave and Tidal Power shoot The Wello Penguin

Orkney Islands Sept 2011 Wave and Tidal Power shoot - The Pelamis Wave Power machine in Orkney - alongside in Lyness - the machine is the P2 . The Pelamis absorbs the energy of ocean waves and converts it into electricity. The machine floats semi-submerged on the surface of the water and is made up of a number of cylindrical sections joined together by hinged joints. As waves pass down the length of the machine these sections flex relative to one another. The motion at each hinged joint is resisted by hydraulic cylinders which pump fluid into high pressure accumulators allowing electrical generation to be smooth and continuous. Control of the resistance applied by the hydraulic cylinders allows generation to be maximised when waves are small, and the machine response to be minimised in storms. All generation systems are sealed and dry inside the machines and power is transmitted to shore using standard subsea cables and equipment.
