Which of the following is NOT a renewable source of energy?

The correct answer is Energy from fossils.

Key Points

• Renewable energy is energy that is produced from natural processes and continuously replenished. 
  • We can also define renewable energy as those energies which can never be depleted. 
  • Few examples of renewable energy are sunlight, water, wind, tides, geothermal heat, and biomass. 
• Energy from fossils
  • Fossil fuels are formed from dead and decayed remains of plants and animals because of their origin fossil fuels have very high carbon content.
  • Coal, natural gas, oil etc are examples of fossil fuels.
  • The reaction involved in the combustion of fossil fuel is: Hydrocarbons + O2 → CO2 + H2O + energy

Additional Information

• Solar energy
  • It is derived from the Sun radiation that is converted by solar panels to generate electricity.
• Geothermal energy
  • ​Geothermal energy is a type of thermal energy that is derived from a heated groundway.
  • It is produced by geothermal plants by using heat from deep inside the earth to generate steam that activates the generator by rotating the turbine to produce electricity.​
• Wind Energy
  • It is a renewable and cleaner energy that produces no greenhouse gas emissions.
  • It is produced energy using wind turbines through wind speed, air density, and blade radius.
  • India is the fourth-largest wind energy producer in the world after China, the USA, and Germany.
  • India ranked 4th in the Global wind power installed capacity index.
  • Tamil Nadu is the first in wind energy production and the second is Gujarat, third in Maharashtra.
