coal be useful in many ways especially for powering electricity
Useful: Energy Light Sound Non-Useful: Electricity C02
When coal is burnt, the energy lost in the form of heat and pollutants such as carbon dioxide and ash is considered as not useful energy. This includes waste heat that is not converted into useful work or electricity.

Solar energy is stored in coal and petroleum.
By burning it, which produces heat

One of the energy releases that isn't useful when coal is burned is thermal energy in the form of heat that is lost to the surrounding environment, rather than being converted into useful work or electricity.
One type of energy released and not useful when coal is burnt is thermal energy in the form of waste heat. This energy is often lost to the environment in the process of burning coal and is not harnessed for productive use.
Coal is a useful material because it is a major source of energy for generating electricity and heat production. It is also used in the production of steel and cement. Additionally, coal can be converted into liquid fuels and other chemicals for various industrial processes.
Well they originate from fossils which are non-renewable.
When coal is burned, the useful energy transfer is in the form of heat, which is typically used to generate electricity in power plants. The heat produced by burning coal is used to heat water and produce steam, which then drives turbines to generate electricity.
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.
