  • Limit the use of non-renewable sources of energy.
  • Save major aspects of energy for the future.
  • Conserve and plant more trees.
  • Individuals need to make good habits of the utilization of energy-saving components and appliances that consume very less energy.

Therefore, it is well described above.
