Question

Which of the following is the renewable source of energy?

• A. Ethanol
• B. Jatropa plant
• C. Bagasse
• D. All of the above

Answer 1

The correct option is D All of the above

• Renewable energy sources are energy sources that are always being replenished. They can never be depleted. Some examples of renewable energy sources are solar energy, wind energy, hydropower, geothermal energy, biomass energy, ethanol, jatropha plant, and bagasse.
• 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.
• So, the correct answer is 'All the above'.
