What does renewable mean?
Renewable describes something that can be replenished, restored, or used again without being permanently exhausted. Its most familiar application is renewable energy, referring to power derived from sources such as sunlight, wind, water, and geothermal heat. Unlike coal, oil, and natural gas, these sources can continue to supply energy because natural processes continually restore them. The adjective can also describe resources, materials, permits, agreements, and contracts that may be renewed or extended. In environmental contexts, the term generally carries a positive connotation because it suggests reduced dependence on finite resources. However, calling a source renewable does not mean that its production is automatically free of environmental impact; land use, wildlife effects, manufacturing, and recycling still matter. The word is therefore especially useful when discussing both long-term resource security and the environmental consequences of energy production.

Where does renewable come from?
Renewable was formed in English by adding the suffix -able to renew, meaning to make new or restore. Both words ultimately trace to Latin renovare, formed from re-, meaning again, and novus, meaning new. Latin descendants and related English words include renovation, renewal, and renounce, although these developed with distinct meanings.
