What are the different types of renewable resources?
This includes wood, sewage, and ethanol (which comes from corn or other plants). Biomass can be used as a source of energy because this organic material has absorbed energy from the Sun. This energy is, in turn, released as heat energy when burned. Hydropower is one of the oldest renewable resources and has been used for thousands of years.
What are the alternative sources of energy?

The most popular renewable energy sources currently are: Solar energy. Wind energy. Hydro energy. Tidal energy. Geothermal energy. Biomass energy.
