Document Summary
Hydro, nuclear and biomass; the fundamentals types of conventional energy alternatives. Nuclear is non-renewable, as it is mined and it also can"t be put back together, once the atoms are split. Japan was one of the top consumer and producer of nuclear power; but after the tsunami, their nuclear power plants were shut down. There"s no energy source that"s benign with no impact at all. Wind moves from an area of high pressure to low pressure. When water moves from high to low, we can extract energy from it. We extract energy from that gradient, in two ways: The impoundment/reservoir approach; we put a dam in the way we allow water to build up behind the dam, then we run water through and it runs a turbine, from which we generate electricity. The run-of-river approach generates energy without disrupting the flow of the river; this approach is much less common, and it is much newer.
