wasted or non-applied energy. Not sure of your question, poorly worded.
Useful energy transfers in the production of electricity using coal occur when heat from burning coal is used to generate steam, which drives turbines to produce electricity. Non-useful energy transfers include heat lost through exhaust gases and in the cooling process of the power plant, which reduce the overall efficiency of the energy conversion process.
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.
The name of the amount of useful energy you get from a system is called "energy efficiency." It measures the ratio of useful energy output to total energy input.
Most of the wind energy will eventually be dissipated by friction (converting it into heat).
Lost energy refers to energy that is dissipated or wasted during a process, often in the form of heat, sound, or other non-useful forms of energy. This energy cannot be recovered or utilized for useful work.
not really, because solar energy can be non useful sometimes
yes, fossil fuel is another name for non-renewable energy sources.
Useful energy refers to the energy that is converted into a form that can directly serve a specific purpose or perform work. It is the energy that is harnessed and utilized to power devices, machinery, or processes effectively, as opposed to wasted as heat or in other non-productive ways.
That may refer to the system's efficiency (which is formally the amount of useful output power divided by the amount of input power).
The known non-conservative forces are force, like friction, where energy gets wasted. This means that useful energy gets converted to unusable energy. You can invent a Universe with non-conservative forces, where you can actually get energy out of nothing, but this is not likely to happen in the real world.
