What is exhaustible energy?

Exhaustible energy is energy produced by sources that cannot be replaced once it is used. Examples are coal, natural gas and oil, which are produced by fossil fuels.

Exhaustible energy pollutes the air and water. The website iperform states that byproducts of these types of energy are acid rain, greenhouse gases and air pollution. Acid rain kills vegetation and pollutes the water. Greenhouse gases change the climate, which can melt ice caps. Air pollution can cause cancer.

Inexhaustible energy is clean energy and never runs out. This type of energy causes little damage to the atmosphere, water or plants. Wind, solar, hydroelectric and geothermal energy are all examples.
