heat energy
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.
Actually it is - very useful.
Currently, gold is not useful in any form of energy production.
electricity
Useful energy is the energy that is converted into a desired form of work or output, such as electricity or mechanical work. Wasted energy, on the other hand, is energy that is not converted into a useful form of work and is typically lost as heat or other forms of inefficiency.
the thing that makes electricity such a useful form of energy is that electricity is renweable it comes from the skies "thunder" you can also generate electircity but still some things need electricity to help it generate. so......... electircity is a useful form of energy, but also wind, solar are also useful for of energy.
Useful energy is energy that is converted into a form that can directly perform work or be easily stored and retrieved for future use. It is typically in a form that can power machines, devices, or appliances efficiently, such as electricity or mechanical energy.
Nuclear energy is not useful in powering a flashlight because it is not readily convertible into electrical energy that can power the light bulb in a flashlight.
Useful energy output refers to the energy that is converted into a form that can directly be used for a desired purpose, such as electricity generated from a power plant. Waste energy output, on the other hand, refers to the energy that is not converted into a useful form and is lost, typically as heat or noise, during the energy conversion process.
By burning it, which produces heat
False
the energy Converter is called FOOD CHAIN or maybe ENERGY PYRAMID :))
