Yo, no energy is unuseful at all we need all of them to surive and to live.
Useful Energy
Torque and horsepower.
Virtually all forms and types of energy are useful in some way or another.
The energy that is not useful is called waste energy. It is the energy that is not harnessed or converted into a form that can be utilized for work or other useful purposes.

A body with mass in motion possesses kinetic energy. If it is subject to friction, either on a rough surface or through the air, some of this energy will be converted to thermal energy, ie it will heat up. An extreme example of this is the re-entry of space vehicles into the atmosphere. It could also be converted to potential energy, such as when you fire a bullet upwards, it eventually stops rising, partly because of friction but also because it is being pulled back by gravity.
Waste energy
Usually, the amount of useful energy after a conversion will be less than the original energy. In no case can it be more.Usually, the amount of useful energy after a conversion will be less than the original energy.

The useful energy that comes out of a light bulb is primarily in the form of light and heat. The electrical energy is converted into light energy that illuminates the surroundings and heat energy that warms up the light bulb and its surroundings.
Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.Energy as such can NOT be destroyed - however, you can convert useful energy into unusable energy.
Currently, gold is not useful in any form of energy production.
