Which description gives the steps for creating hydroelectric power?

river water stored in a reservoir flows through a turbine and into a channel in a dam. at the end of the channel, the water turns a generator, which produces electricity; then the water flows back upstream. river water enters a dam through a generator. the movement of the water through a generator produces electricity.

How is hydroelectricity produced in dams?

Conventional (dams) Most hydroelectric power comes from the potential energy of dammed water driving a water turbine and generator. A large pipe (the “penstock”) delivers water from the reservoir to the turbine.

What equipment is needed for hydroelectric energy?

The major components of a hydroelectric plant are a river, dam, turbine, generator, and power cables. All the components work together to generate electricity. A river that typically has a large drop in elevation at some point is ideal for a hydroelectric plant.

How do we recover hydropower?

Some of the energy used to move and treat water can be “recaptured” through energy recovery hydropower. Energy recovery hydropower harnesses mechanical energy from moving water that is unutilized within existing pressurized water supply pipelines and converts it to electricity.

What are advantages of hydropower?

Because hydropower plants can generate power to the grid immediately, they provide essential back-up power during major electricity outages or disruptions. In addition to a sustainable fuel source, hydropower efforts produce a number of benefits, such as flood control, irrigation, and water supply.

How long do hydropower plants last?

100 years

How does a hydropower plant work?

Hydropower plants capture the energy of falling water to generate electricity. A turbine converts the kinetic energy of falling water into mechanical energy. Then a generator converts the mechanical energy from the turbine into electrical energy.

What does hydropower mean?

Hydro power is electrical energy produced through the power of moving water. In modern technology, hydropwer moves turbines that pass on their energy to a generator which then produces electric power. Hydropower is a type of renewable energy, and once the power plant is constructed it produces little to no waste.

How many countries use hydropower?

More than 150 countries produce some hydroelectricity, although around 50% of all hydro-power is produced by just four countries: China, Brazil, Canada, and the United States. China is by far the largest hydro-power producer on the planet, as shown in the figure below.

Which country produces the most hydropower?

China

Why does China use hydropower?

Naturally China wants to exploit this potential and build new hydropower stations, mainly for two reasons: to satisfy need for energy with energy source within its borders and to reduce use of ecologically unacceptable coal that is dominant fuel in China’s big economic growth, but which use causes air pollution and …
