Fossil fuel. Also, natural gas is in the category of fossil fuels.
it is stored as something called prototype energy which is energy, a little more abundant than fossil fuels. +++ "prototype energy" doesn't exist. The energy stored in any fossil fuel, or in materials like wood, is potential chemical energy,
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.
The energy from the petroleum is only accessable when the fuel is burnt, if the petroleum itself doesn't undergo burning the energy isn't released. So the energy is called 'stored' or 'potential' energy.
Solar energy is stored in coal and petroleum.
