Sustainable energy [SEP] Background
Providing sustainable energy is widely viewed as one of the greatest challenges facing humanity in the 21st century, both in terms of meeting the needs of the present and in terms of effects on future generations. Bill Gates said in 2011: Worldwide, 940 million (13% of the world) people do not have access to electricity, and 3 billion people rely on dirty fuels for cooking.
