Energy supply

Energy supply, total amount of energy available, from all sources, including fossil fuels (coal, oil, natural gas), water power, nuclear energy, solar energy, wind power, etc. Currently, fossil fuels supply the great majority of energy used in industry. The pollution caused by these fuels has stimulated the search for alternate sources of energy that would be clean, practical, and renewable.
