Generation
Hydroelectric power is the generation of electric power from the movement of water. A hydroelectric facility requires a dependable flow of water and a reasonable height of fall of water, called the head. In a typical installation, water is fed from a reservoir through a channel or pipe into a turbine. The pressure of the flowing water on the turbine blades causes the shaft to rotate. The rotating shaft is connected to an electrical generator which converts the motion of the shaft into electrical energy.
Small hydro is often developed using existing dams or through development of new dams whose primary purpose is river and lake water-level control, or irrigation. Occasionally old, abandoned hydro sites may be purchased and re-developed, sometimes salvaging substantial parts of the installation such as penstocks and turbines, or sometimes just re-using the water rights associated with an abandoned site. Either of these cost saving advantages can make the ROI for a small hydro site well worth the use of existing site infrastructure & water rights.

Famous quotes containing the word generation:
“What an infernal set of fools those schoolmarms must be! Well, if in order to please men they wish to live on air, let them. The sooner the present generation of women dies out, the better. We have idiots enough in the world now without such women propagating any more.”
—Elizabeth Cady Stanton (1815–1902)
“Through centuries he lived in poverty.
God only was his only elegance.
Then generation by generation he grew
Stronger and freer, a little better off.
He lived each life because, if it was bad,
He said a good life would be possible.”
—Wallace Stevens (1879–1955)
“Today’s comedian has a cross to bear that he built himself. A comedian of the older generation did an “act” and he told the audience, “This is my act.” Today’s comic is not doing an act. The audience assumes he’s telling the truth. What is truth today may be a damn lie next week.”
—Lenny Bruce (1925–1966)
