Useful energy is defined as the energy that can be easily converted and utilized to perform useful work, such as electricity or mechanical work, without being wasted. It is the energy that directly contributes to performing tasks and activities, unlike wasted energy that is lost as heat or in other forms without being used productively.
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.
That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).
Energy efficiency is typically determined by the ratio of useful energy output to total energy input in a system. It can be quantified by calculating the efficiency percentage, which is the amount of useful energy produced divided by the total energy input multiplied by 100. The higher the percentage, the more energy efficient a system is.
Efficiency is the ratio of useful energy output to total energy input. A higher efficiency indicates that a greater proportion of the total energy input is being converted into useful energy output. Therefore, as efficiency increases, the amount of useful energy output relative to total energy output also increases.
The amount of useful energy obtained from an energy conversion process is referred to as energy efficiency. It is calculated by dividing the useful output energy by the total input energy and expressing it as a percentage. Energy efficiency is an important factor in determining the overall effectiveness and sustainability of an energy conversion process.
Energy is the ability to cause changes in matter. It's hard to answer because you define the word "energy" in different ways. I hope this answer can be useful.. :)

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.
