Chapter 8.3, Problem 18R

To determine

The single energy source on which other alternative energy source depend directly or indirectly.

Answer to Problem 18R

The sun is the single source of the energy directly or indirectly for other alternative sources of energy.

Explanation of Solution

Introduction:

The biomass energy, hydroelectric energy, solar energy, tidal energy and wind energy are the alternative source of the energy. These are primarily used to generate the electricity.

The biomass produced due to the trees' conversion into biomass due to the sun's energy. The temperature of the atmosphere increases due to the energy of the sun. The increase in the atmospheric temperature controls the other atmospheric factors like wind flow and rain. The wind energy, tidal energy, and hydroelectric energy depend on wind flow and hydraulic energy. The sun is the single source of the other alternative energy source.

Conclusion:

Thus, the sun is the single source of the energy directly or indirectly for other alternative sources of energy.
