Best Answer

Hydroelectric plants use the running water by a turbine with blades on it, and when the water flows through these turbines they rotate,. in turn rotating the alternators that make the electricity which is sent from the power-station via the wires to houses, businesses etc that need the electricity.

What involve the conversion of gravitational potential energy into electric energy - wind electric generators or hydroelectric power plants?

Hydroelectric power plants convert GPE into electric energy. When the water flows from the higher point to the lower point, hydroelectric turbines convert the energy of the flowing water into energy.


Can you generate electricity by gravitational energy?

Sure, it is commonly done, in hydroelectric plants. The energy from the falling water is converted into electricity. Please note that it takes energy to get the water up again. This occurs in nature due to the Sun's energy.Sure, it is commonly done, in hydroelectric plants. The energy from the falling water is converted into electricity.

In hydroelectric power plants the energy from moving water is converted into electric power. What kind of energy transformation occurs when the energy is converted?

mechanical to electrical


What is a draw back for hydroelectric energy?

Hydroelectric power plants generate very little electric current for the cost of building, using, and maintaining the equipment used to produce it.


Why do hydroelectric power plants produce only about 3 percent of the electrical energy in the world today?

it not that efficient

Can hydroelectric be converted into heat?

Every energy conversion process produces heat because of frictional forces. This is why no source of energy can be 100% converted into usable energy. But for your purpose I assume a simple yes would work. Many power plants rely on hydroelectric processes to produce energy. This energy travels to a community where it can be harvested for heat.


Where in the world have they begun using or testing hydroeletric energy and how has it been working?

Hydroelectric plants have been used for nearly 100 years and work quite well.


What kind of plants are used to make electricity from dams?
