Which statement best explains why electricity should be conserved?
fossil fuels generate electricity and are limited in supply.
fossil fuels generate electricity and are expensive.
power plants use a lot of resources and never produce a lot of electricity.
power plants can use only one type of resource to produce electricity.

Fossil fuels generate electricity and are limited in supply.

The correct answer is "Fossil fuels generate electricity and are limited in supply".

Explanation:

Fossil fuel is obtained from the dead remains of the plants and animals buried under the land for billions of years ago.

The examples of fossil fuels are petroleum and coal. They are limited on the earth. They are non renewable as it takes billion of years to obtain the fossil fuel. The electricity is generated by using fossil fuels. If they are finished then they cannot be replaced immediately with an alternative source.

Therefore, electricity should be conserved because fossil fuels generate electricity and are limited in supply.
