Correct Answer - Option 3 : Nuclear energy

The correct answer is Nuclear Energy.

  • Renewable energy is also known as clean energy which is obtained from natural sources and can be replenished.
  • Solar energy, wind energy, hydroelectric power, biomass energy, geothermal energy, and tidal energy are examples of renewable sources of energy.
  • Energy is free in nature, some are infinitely available, called sustainably, and some are called non-renewable.
  • It is our duty to ensure that sustainable and non-renewable technology is used properly.
  • Non-renewable electricity is a finite resource that can inevitably run out over time.
  • Non-renewable energy does not regenerate itself at a reasonable pace for sustainable economic extraction within meaningful human timeframes.
  • Non-renewable energy is fossil fuel energy, such as coal, crude oil, natural gas, and uranium.
  • Unlike renewable energy, non-renewable energy requires human interference to make it suitable for use.
  • Fossil fuels are primarily fossil.
  • Fossil fuels are thought to have been produced more than 300 million years ago when the planet was very different in its landscape.
  • Types of Non-renewable resources:
    • Fuels which are formed by remains of animals and plants
    • Divided into further three categories: Natural Gas, Oil, and Coal
    • Thermal Electricity uses Coal for heat production and converts that heat into electricity.
    • Nuclear fuels: The use of fission-based nuclear energy requires naturally occurring radioactive material as a reactor.
      • Uranium is the most natural fission fuel and is found in the soil at extremely low concentrations and extracted in 19 countries.
      • Nuclear power generates approximately 6 % of the world's oil and 13-14% of the world's electricity.

  • The difference between renewable and non-renewable sources of energy.

Renewable sources of energy

Non-renewable sources of energy

Renewable sources of energy are the natural resources that get replenished from time to time.

Non-renewable sources of energy are obtained from the earth’s crust and once used they disappear.

These resources do not cause any pollution.

These resources cause pollution.

Solar energy and wind energy are examples of renewable sources of energy.

Fossil fuels and natural gas are examples of non-renewable sources of energy.
