Some is used to drive the display, whether a CRT or LCD, and some is used to produce the audio signal, whilst some is used to power the circuits that decode the input signal. There is also some wasted energy from electronic parts that get warm, this is convected out of the grilles in the back.
The energy that is not usefully transferred by solar cells is typically dissipated as heat. This occurs when the energy is not converted into electrical energy due to inefficiencies in the solar cell's conversion process.
The useful energy transferred in a hoover is converted into kinetic energy to power the motor that drives the vacuum cleaner. This kinetic energy is then used to create suction that picks up dirt and debris from surfaces.
No, not all energy transferred during an energy change is always useful. Some energy may be lost as heat or sound, decreasing the overall efficiency of the energy transformation. This is known as energy wastage, and it occurs in many natural and human-made processes.
In theory, energy can be transferred multiple times in various forms such as from one object to another or between different forms like potential and kinetic energy. However, with each transfer, some energy may be lost as heat due to inefficiencies in the system, so there is a practical limit to the number of times energy can be transferred before it becomes too low to be useful.
Kinetic energy is transferred to electrical energy.

Chemical energy is transferred to electrical energy! :) :p

The useful energy will be gone eventually, one way or another. As a result of the Second Law of Thermodynamics, it is unavoidable that we will eventually run out of useful energy.
vague question. Efficiency in terms of energy = useful energy/total energy x 100 vague question. Efficiency in terms of energy = useful energy/total energy x 100
Most of the wind energy will eventually be dissipated by friction (converting it into heat).
The generators transfer mechanical energy into very useful electrical energy.

Basically, the Universe will eventually run out of fuel - of useful energy.
Kinetic energy is transferred to electrical energy.
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.
