The useful energy in a radio is the electrical energy converted into radio waves that transmit sound through speakers, allowing us to listen to music or news.
A radio produces electromagnetic energy in the form of radio waves that are converted into sound waves by the radio's speaker, providing audible information and entertainment.
When a radio is not 100 percent efficient, it means that not all the electrical energy input is converted into useful radio frequency output. Some energy is lost as heat or in other non-useful forms, resulting in less effective performance and potential inefficiencies in power consumption.
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.
In a battery-operated radio, electrical potential energy from the battery is converted into electromagnetic energy in the form of radio waves and sound energy when the radio is turned on and emits sound.
In a battery-powered radio, chemical energy stored in the battery is transformed into electrical energy when the battery provides power to the radio's circuitry. This electrical energy is then transformed into sound energy and electromagnetic energy (radio waves) as the radio converts the electrical signals into sound waves that we can hear.

Radio is useful for the older generation, if somebody is unable to see/watch the television radio is the next best thing!
A radio produces sound, and therefore sound energy. The radio waves, however, are electromagnetic energy, not sound. The function of a radio is to convert that electromagnetic energy into sound 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.

Radio telescope can "see" radio spectrum events and locations in the universe.
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.
