By burning it, which produces heat
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.
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.
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.
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.

it provides energy without burning coal.
The type of energy released by coal that is not useful is primarily in the form of waste heat. During combustion, a significant portion of the energy generated is lost as heat rather than being converted into useful work or electricity. This waste heat contributes to inefficiencies in energy production, as only a fraction of the energy content of coal is effectively harnessed for practical use. Additionally, byproducts such as carbon dioxide and other pollutants are released, further diminishing the overall utility of the energy produced.
The energy stored in coal that is converted to heat is chemical energy. Of course coal, like any other matter, also has stored nuclear energy.
Chemical energy is transferred to electrical energy! :) :p
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.
Solar energy is stored in coal and petroleum.
No, it is a non-renewable form of energy.
