Energy saving button / button

We know very well that we need to save energy,but not many people actually practice it in everyday life.
Lots of energy is being wasted daily. (e.g.- In many cases TV sets, computers or lighting equipment are turned on without people using them.) So, is there any good way to change people's awareness so that they can save energy? With the power button sign, the energy saving button displays the truth that you can save nature by turning off idle home appliances. The button makes the user recognize that energy is nature whenever they turn on or off home appliances.
