chemical potential energy (in the fuel being burned) to heat (thermal) energy and a little light energy.
Potential
Some fuel is burned; if you assume a chemical fuel (e.g., coal or petroleum), the chemical energy in the fuel is converted to heat. Then, this heat is converted to movement energy, which in turn is converted into an electric current.Note that when you have heat, only part of the heat energy can be converted to useful energy. The theoretical maximum is defined by the Carnot formula.
This happens in the fuel rods, the energy released by nuclear fission appears initially as kinetic energy of the fission fragments, which is quickly turned into thermal energy as the fragments slow down and are stopped in the fuel. Thus the fuel rods heat up and transfer thermal energy to the coolant, which in most reactors is water but can be gas or liquid metal.
Energy is never lost, it is transformed into different types or transferred into different systems. Some of this is useful energy, for example thermal energy used to power a turbine or generator. Some of this thermal energy is not useful, and instead just heats up the fuel container or components of the generator. This energy has still come from the fossil fuel being burned, but it has not been transferred into the system for generating electricity.
Chemical Energy is what is released.
When a fossil fuel is burned chemical energy that is stored within the fuel is released via combustion. This then turns into steam which turns turbines to form electrical energy. So Chemical to heat to mechanical to electrical
chemical potential energy (in the fuel being burned) to heat (thermal) energy and a little light energy.
When a fuel is burned, it is a combustion reaction. This reaction breaks apart chemical bonds and releases the energy stored in them.
A fossil fuel contains chemical energy. When it is burned this is turned into thermal or heat energy. This then may be converted into some other form including kinetic energy.
Fossil fuels contain chemical potential energy, which is released as thermal energy when they burn. Nuclear fuel which can undergo fission contains energy by virtue of the change of mass which occurs when the nucleus is split into fragments, initially this is released as kinetic energy which is absorbed in the fuel and released as thermal energy.
When fossil fuels are burned they turn into mercury which released into the atmosphere
