Energy in the 21st Century / The Alternatives
Caption Description
The high price of oil, increasing worldwide demand for energy and awareness of the environmental problems associated with hydrocarbon fuels have made development of alternative energy sources essential. In August 1981, a United Nations Conference was held in Nairobi, Kenya, focusing on fourteen alternatives: solar energy, geothermal energy, hydropower, wind power, biomass, fuelwood and charcoal, oil shale and tar sands, ocean energy (thermal gradient, wave and tidal power), peat and energy from draught animals.
In this solar distillation plant in New Delhi, water is heated under glass using the 'greenhouse effect' and it evaporates on the glass, it is collected in its distilled form. This plant distils around 90 litres of water a day for laboratory use. [No exact date]
