Energy Efficient Electrical Dimmers

If you have old dimmers with the turn knob on them, is it a good idea to replace them? Yes, it is a great idea. Actually, using dimmers are supposed to save energy. And it does not. On old dimmers, they increase the amperage and increase the resistance. That in turn will increase heat which makes more amperage on the circuit. So actually, resistance did not do anything but dim your lights a long time ago. But that was all it was supposed to do, dim
