Renewable vs Nonrenewable

Biomass is plant material used to make biofuels and to produce biopower. Therefore, biofuels are renewable. Renewable energies like biofuel, solar power, and wind power, are important to our future because they don't run out. Natural forces constantly renew, or replenish them.

While we do use renewable energy in some places, most of our energy comes from a nonrenewable source, fossil fuels. We burn fossil fuels, including coal, oil, and natural gas, for energy.
