Renewable Energy

Renewable energy sources consist of the sun and the wind. Harnessing energy from water currents, tides, and waves also described  as types of renewable energy. In opposition, the traditional energy sources we depend on to generate power namely natural gas and oil and coal are non-renewable sources of power. Once these resources are sufficiently depleted they become too expensive and costly to retrieve.
Mind it, not all renewable energy sources come devoid of consequences (think about issues surrounding hydroelectric dams in the West). Solar power has the unique advantage of tapping energy from the sun without actually impacting any other natural resource.
