A river valley, with adequate flow, and sufficient gradient, and a sufficiently large surface area of water storage; these are the needs for an hydroelectric power station.
Sometimes, the water from one water catchment may be led via a tunnel to a discharge site which offers an overall better fall.
Mechanical energy in the form of E= mgh, water falling, goes in and electrical enegy comes out.
No. Tidal energy is an inexhaustible form of hydroelectric power that uses only the energy from the changing of the tides to create energy instead of burning or consuming any form of energy source to create it. Thus, it produces no unsafe greenhouse gases or hazardous waste materials.

Both. Some kinds are natural and some man-made.
Hydroelectric power is a great way to keep our environment clean. Unlike gasoline, hydroelectric power combusts to form water as a byproduct which does not harm earth.
HYdroelectric power is pretty cool and here is a diagram:

Hydroelectric is ultimately solar power. The water that powers the dams is brought in from the ocean by solar evaporation that returns to the earth in the form of rain or snow. Aside from the costs (not just money but also environmental) of building dams, hydroelectric power is free for the taking.
