I think you mean conservation of energy. This means to use electricity, gas, water ,heat etc wisely in order to reduce the strain on our energy sources.
What Does 'Conversation Of Energy' Mean?
The correct phrase is "conservation of energy". On the other hand it can be "conversation on energy" not "of energy".
The first law of thermodynamics tells us about the conservation of energy. The law states that the total amount of energy remains constant, no matter it changes the form of energies.
