A renewable resource (Risorsa rinnovabile) is a resource which can be used repeatedly and replaced naturally. Examples include oxygen, fresh water, solar energy and biomass. Renewable resources may include goods or commodities such as wood, paper and leather.
Gasoline, coal, natural gas, diesel, plastics and other fossil fuels are not renewable. They take millions of years to be made, and cannot be renewed in a human lifetime or even a nation's lifetime. Ways have been developed to make biodegradable plastic and biodiesel and other fuels from renewable resources such as corn, sugar cane, soybeans and canola.
Renewable resource harvesting and use typically do not produce pollution or contribute to global warming. The use of renewable resources and energy sources is increasing worldwide, with certain nations, such as Bhutan, and US states, such as California, beginning to rely entirely on renewable energy. From 2008 to 2012, the U.S. doubled renewable generation from wind, solar, and geothermal sources. America and Britain are now home to some of the largest wind and solar farms in the world.
