Biomass, WIND, and SUN are all renewable energy sources. Biomass is a form of energy derived from organic matter such as wood, crops, and animal waste. WIND energy is generated by the movement of air, which is converted into electricity by WIND turbines. Solar energy is energy from the SUN that is captured and converted into electricity or used to heat water. All three of these renewable energy sources are important for reducing our dependence on fossil fuels and helping to protect the environment.
