Hydroelectricity

Abstract

Hydroelectricity is probably the cheapest and most reliable source of renewable energy, and it has not yet reached its limit of expansion either in US or in the world. As a result, it can and should be a significant future contributor to the energy supply. But hydroelectricity has its detractors because it depends on dams that impact fish migration and spawning regions and otherwise change the ecology of the river. There are solutions to these problems, but environmental concerns remain prevalent.
