The use of water to generate mechanical power is a very old practice. A flowing stream can make a paddle turn, but a waterfall can spin a blade fast enough to generate electricity.

Water constantly moves through a vast global cycle, in which it evaporates (due to the activity of the Sun) from oceans, seas and other water reservoirs, forms clouds, precipitates as rain or snow, then flows back to the ocean. The energy of this water cycle, which is driven by the sun, is tapped most efficiently with hydropower. .....more.
