Hydroelectric – The Forgotten Giant Of Clean Energy
Hydroelectricity is the most widely used form of clean renewable energy in the world, generating over 19% of the world's electricity. It requires no fuel and produces no direct emissions or by-products. The United Nations estimates that the technically exploitable potential for hydropower is 15 trillion kilowatt-hours per year, amounting to half of the total projected global electricity needed in 2030. In the United States, hydropower has fallen to 10% of the electricity supply mix down from14%, 20 years ago. In terms of electricity production, hydropower accounts for only 7% of America's current power needs.
