A renewable resource is a resource which can be used repeatedly and replaced naturally. Renewable energy almost never runs out, for example: solar energy is powered by heat from the sun and never runs out. Examples include oxygen, fresh water, solar energy and biomass. New resources may include goods or commodities such as paper and leather.
Gasoline, coal, natural gas, diesel, plastics are other fossil fuels are not renewable. They take millions of years to be made, and cannot be renewed in a human’s, or even a nation's lifetime. Ways have been developed to make biodegradable plastic and bio diesel and other fuels from renewable resources such as corn, sugar cane, soybeans and canola.
