What loses energy when you use tidal power plants?

User Avatar

Asked by Wiki User

Tidal power plants harness the energy from ocean tides, which is primarily derived from the gravitational pull of the moon and the sun. In using this energy, the kinetic energy of the moving water is partially converted into electricity, meaning the water loses some of its energy as it flows through the turbines in the power plant.

Can manure make energy?

User Avatar

Asked by Wiki User

Yes, manure can be converted into energy through a process called anaerobic digestion, where microorganisms break down organic material to produce biogas (methane and carbon dioxide). Biogas can then be used to generate heat and electricity through combustion or in a biogas generator. This process helps to produce renewable energy and also reduces methane emissions from manure.

Why do hydro electric power stations need to be located at dam walls?

User Avatar

Asked by Wiki User

Hydroelectric power stations need to be located at dam walls to take advantage of the potential energy created by the difference in water levels. Water stored in the reservoir behind the dam can be released and flow through turbines located at the base of the dam, generating electricity as the water flows downhill. This setup allows for the conversion of gravitational potential energy into electrical energy.

Where is Tidal Energy found on Earth?

Tidal energy is found in coastal areas where there are strong tidal currents. These areas, such as bays, estuaries, and straits, experience regular and predictable tidal movements that can be harnessed for generating electricity using tidal turbines.

How is water use to make electricity?

User Avatar

Asked by Wiki User

Water is allowed to fall from some height into a turbine. The height the water falls increases its kinetic energy. That is why dams are so tall. The turbine rotates. the turbine is mounted on a shaft. The shaft is connected to the shaft of a generator. When the generator is spun by the turbine, it makes electricity.

Water actually does not fall but rather flows down stream at high velocity and great pressure.

it also saves much more money and if we only use it we will be stoping polution and we can reuse it.
