when you watch tv you use electrical energy
When you watch TV, electrical energy is being converted into light energy and sound energy. The electrical energy powers the screen, which emits light for you to see, and it also powers the speakers, which produce sound waves for you to hear.
Electricty is used for a television.

Some ways to reduce how much energy is wasted would include, shutting off any lights that are not being used. Set thermostat to 78 and leave it. Turn the TV off and go for a walk.
By being plugged into the electrical socket in the wall that gives it electricity.
Energy that is not being used is called potential energy.
Energy can neither be created or destroyed. It can only be changed from one form into another. So the real question is... what does your TV set do with the energy it gets? Two obvious things are it creates light which you see as a picture and it creates sound which you hear, both are forms of energy. Another thing your TV makes is heat. The circuits inside your TV have some resistance which creates heat although not alot it accounts for some of the energy being used. hope this helps.
