Biofuels and Bioenergy

Renewable Energy

Renewable energy is characterized as an energy resource that can be naturally renewed or regenerated over a short time and is derived directly or indirectly from the sun (solar energy), wind energy, hydropower energy, bioenergy, or other natural resource mechanisms (geothermal energy, tidal energy). Natural processes produce renewable energy, which is continually recycled. Sunlight, fire, wind energy, tides, water and various types of biomass are all examples. This energy never runs out and is continually replenished.
