Chapter 8.3, Problem 15R

To determine

The three methods to use solar energy.

Answer to Problem 15R

The solar energy can be used to generate electricity, to cook foods, and for the heat input in thermal power plants.

Explanation of Solution

Introduction:

Solar energy is a renewable form of energy. Pollution does not occur in the production of solar energy. It can work as the input to produce other forms of energy.

The solar energy can be used in the many forms in which the three methods are the following:

• Solar energy can be converted into electrical energy by using photovoltaic cells.
• The solar energy can be used to dry the farm produce and to cook the food by using the solar cooker.
• The solar energy can be used as the heat input in the thermal power plant.

Conclusion:

Thus, solar energy can be used to generate electricity, to cook foods and for the heat input in thermal power plants.
