The energy turns into light,to create the picture on the telivision.
To turn it on you use mechanical energy produced in the muscles in your hand. To energise the TV you use electrical energy
radiator toaster microwave there's 3 random ones !
Example: TV. Electricity- Heat, light, sound. Useful energy transfers would be electricity- light, sound because that's what your TV actually needs, but electricity- heat would be wasted energy or a non-useful energy transfer because your TV does not need to produce heat, unless of course you can't afford central heating, but then isn't heating more important than a TV???? Summary: Useful energy transfer: The purpose of the object is fufilled by this transfer. Non-useful energy transfer: The purpose of the object is not fufilled by this transfer, and in effect, this transfer is a "side effect" of the useful energy transfer. These transfers waste energy.

Mechanical energy into electrical energy
electrical energy turning into macanic energy:)
If a person has to turn on their VCR in order to turn on the TV, then the VCR is working as the input and the output. If you do not want this to happen, disconnect the cables from the VCR and directly connect them to the TV.
To turn it on you use mechanical energy produced in the muscles in your hand. To energise the TV you use electrical energy
The main input energy is electrical energy from mains or power sockets; that energy is transferred to light energy for the pictures, and also there is sound energy (For audio), and all these energy are converted right back at heat energy as there is always a loss of energy in every device.

turn off lights when no it the room. turn of televisions when not watching them. use solar powered energy
