Hydroelectric power has been touted as the 'environmentally clean, renewable source of power.' This is subject to debate, as hydroelectric dams use turbines to generate electricity, and these turbines are spun by shafts which have blades on them. Fish which get caught in the high-pressure streams of water directed at the turbine blades usually do not survive the encounter with the blades. Also, the impoundments, or lakes, behind hydroelectric dams slow the speed of the river so much that many young fish do not survive the long swim to the ocean, where food is plentiful in comparison to rivers. Of course, dams present a complete barrior to upstream migration, unless fish ladders are in place, and even fish ladders are not 100 percent effective, as many fish are unable to locate the ladders. Salmon populations upstream of Grand Coulee Dam, which does not have fish ladders, disappeared, except for the freshwater varieties.
Anything that uses the force of a falling object to do work. For example, water mills, hydroelectric power generators, pile drivers. Even a person jumping (up and) down on earth to flatten it.
You probably mean "hydroelectric power". It basically means the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most used form of renewable energy.

There are two measures of production costs: total costs and marginal costs. The relevant ratio depends on which of these is being minimised.
hydroelectric energy is energy that comes from water
amount of hydroelectric energy is available
What city runs on Hydroelectric energy?
hydroelectric energy is found in the earth core
Since hydroelectric energy supplies electricity, any industry that uses electricity from a hydroelectric plant relies on this energy.
hydroelectric energy is free to the fuel fossil
energy moves through hydroelectric energy because of all the heating and the movement of the whole source
who invented hydroelectric energy
A water turbine dam is an example of hydroelectric energy. Hydroelectricity is an important part of the energy mix in the world.
Where is hydroelectric energy generated?Hydroelectric energy, being electricity generated from a hydro (water) source, usually a hydro-electric dam, can be found anywhere on the electrical grid.
hydroelectric power is an important for producing the power in the low loss of energy..energy is nothing but producing the power....so we can easily produce the power from hydroelectric power plant.
