Hydroelectricity

Hydroelectric power offers a cleaner energy alternative to coal- and crude petroleum-powered electricity. Hydroelectricity accounted for 18 percent of global electricity supply in 2006. Currently, 97 percent of global electricity generation from renewable sources is obtained from hydroelectricity. It has been projected that hydropower would generate approximately 1.8 trillion kilowatt-hours (kWh) of electricity by 2030, representing 54 percent of total electricity from renewable energy sources. Hydroelectric power presently occupies significant portions in the electricity mix in both developed and developing countries including (but not limited to) Norway (99 percent hydroelectric), New Zealand (75 percent), Canada (61 percent), Sweden (44 percent), Brazil (86 percent), Ghana (67 percent), Venezuela (67 percent), China (22 percent), Russia (18 percent), and India (16 percent).
