The types of renewable resources may be solar energies which are obtainable using the energy that comes from the sun, wind energies which are energies from the wind, hydropower which is an energy that comes from water and heat energy which comes from underground.
Common examples of sources of renewable resources are alcohol which can be used in the production of biodiesel, corn which can be used to make ethanol, animal fat for bioplastic or biodiesel, manure for methane and production of biogas, and sugarcane for ethanol.
