Chapter 8, Problem 10STP

To determine

The reason that hydroelectric power plants are almost twice efficient as fossil fuels and nuclear power plants.

Explanation of Solution

Introduction:

The kind of power plant in which the water is used to produce the electric energy is known as hydroelectric power plant.

In the hydroelectric power plants the main source of the energy is water and it is freely available at almost every places. Whereas the source of nuclear power plants and fossil fuels are not freely available, due to which the input cost is very less in hydroelectric power. This is reason that hydroelectric power plants are almost twice efficient as fossil fuels and nuclear power plants

Conclusion:

The hydroelectric power plants are almost twice efficient as fossil fuels and nuclear power plants because the input cost is very less.
