What is Renewable Energy?

RRenewable energy is energy derived from naturally-occurring sources that can be constantly replenished such as solar, wind and hydroelectric power.

This contrasts with energy sources like oil and coal, which rely on burning a material which must be found extracted and is not recreated.
Renewable energy is often associated with environmentally-friendly, or green energy, since it largely involves the use of clean natural resources, though certain types of renewable energy do produce pollution, and some even argue nuclear power is a renewable energy source.

As the global demand for energy increases, renewable energy has become an increasingly important focus around the world, as relying on non renewable energy sources is an unsustainable practice in the long run.
