Answer 2

Water stored in large reservoirs is piped downhill (by gravity) to drive turbines connected to alternators. The used water is simply discharged back into the river below the power-station. The output from the alternators is transformed up to a very high voltage for efficient transmission over long distances, and fed into the grid for distribution.

There is a variation called "Pumped Storage" where water is used for generation at peak demands, but then captured in large lower reservoirs. During off-peak times (typically early hours of the morning), electricity generated elsewhere is then used to drive pumps that return the water to the top reservoir. This is done to even out demands on the generating stations and grid generally.

Note: Turbines do not generate electricity. A turbine is simply a motor driven by a constant stream of fluid such as water, gas or steam. It's the alternator that makes the electricity.

Answer 3

first of all, you wanted to ask "How is HydroELECTRICITY produced" (or that's what I think you are asking).

okay to the answer: hydroelectricity is produced in hydroelectric dams, where water is contained. this water that rises a lot, enters through pipes which direct the water down to the bottom of the dam; afterwards, the water that fell a terrific height gets to the bottom of the dam where it hits a generator, which has a turbine which in turn is moved by the water. the astounding speeds move humongous magnets, which are surrounded by strands of some metal (copper I think) which finally produce electricity. My answer might be a little incomplete, so you might want to Google an answer. ++++ I can supply a much more coherent answer that puts it all in the correct order! Water stored in reservoirs is piped downhill, creating considerable pressure by the height difference, to drive turbines connected to alternators. An alternator holds a series of copper coils or bars on a rotor that is revolved at a few hundred rpm so they cut across a magnetic field, thus inducing an electric current in the circuit connected to its output. This circuit at the power-station consists of a transformer that raises the voltage considerably to transmit the electricity over long distances at fairly low current, for high efficiency. (E.g. for 1MW, as W=VI, a transmission voltage V of 100 000V would draw a line current I of only 10A.)
