All of the above

  • Ethanol, derived from plant material, is a renewable energy source because the production and combustion of ethanol complete a cycle.
  • The oil from Jatropha plants is mainly converted into biodiesel for use in diesel engines(biodiesel).
  • Bagasse is the dry pulpy residue left after the extraction of juice from sugar cane. Bagasse is usually combusted in furnaces to produce steam for power generation. 
  • Hence ethanol, jatropha plant and Bagasse are the renewable sources of energy.
