Question

Explain why hydroelectric power plants are almost twice as efficient as fossil fuel or nuclear power plants.

Answer 1

because it produces more energy and also the amount of water is unlimited as compared to fossil fuels or a nuclear plant.

Answer 2

ANSWER:  

As hydroelectric plant produces more energy than nuclear power plants and fossil fuels, it is twice as efficient than them.    

EXPLANATION:

The Efficiency of hydroelectricity produced by the power plant is high as 85% to 90% whereas the nuclear power plant has an efficiency of about 55%. This is because of the following reasons.

• The source of power plant is water, which is of no cost as it could be obtained through rainfalls and running costs are not required, whereas the source of nuclear power plant is Uranium which is too complex to obtain.

• Even the maintenance cost of Hydro power plant is low when compared to nuclear power plants as nuclear.
