renewable
Americanadjective
noun
-
Relating to a natural resource, such as solar energy, water, or wood, that is never used up or that can be replaced by new growth. Resources that are dependent on regrowth can sometimes be depleted beyond the point of renewability, as when the deforestation of land leads to desertification or when a commercially valuable species is harvested to extinction. Pollution can also make a renewable resource such as water unusable in a particular location.

Etymology
Origin of renewable
Explanation
Anything renewable can be replaced or has an endless supply. Renewable sources of energy don't run out. Since re means "again," things that are renewable are always fresh and new: the supply can't be used up. This word often applies to energy. Fossil fuels like oil are not renewable resources; we will run out of oil someday. Energy sources like solar and wind power are renewable, because there's always going to be sunlight and wind. Anything renewable is going to last.
