Energy conservation is the effort made to reduce the consumption of energy by using less of an energy service. This can be achieved either by using energy more efficiently (using less energy for a constant service) or by reducing the amount of service used.
Saptagir considers that energy conservation is a key factor which benefits the organization in the long run towards the energy management. Energy conservation mechanisms not only reduce the energy load, but also reduce the pollutants, GHG emissions into the environment.
