When you burn a fuel in air you are converting chemical potential energy into thermal energy. The only energy input needed is to raise the fuel temperature to the ignition point. To obtain electromagnetic energy you have to drive a generator, which requires mechanical energy, so you have to use the thermal energy to drive a heat engine, a gas turbine is a good example.
endothermic energy
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.
A car's energy source is the chemical energy of it's fuel. This energy is liberated as thermal energy in the pressurized heated gas products. The expansion of the gases in the engine's cylinders, now mechanical energy, is directed toward the mechanical devices that will direct this energy to the rotation of the wheels. A car's engine is a heat engine. It transforms thermal energy in the form of heat to mechanical energy. But according to thermodynamics 2nd law, it cannot transform all of the heat to mechanical energy, just some amount. The rest of the heat has to be dissipated to a low temperature heat deposit (or heat sink). That's why a car needs a heat dissipating system (the radiator).
The original energy source is of course the Sun - lighter fuel stores ancient Sunlight energy in the form of chemical energy. When the lighter is used this chemical energy is converted into a flame which is both thermal energy (heat) and electromagnetic energy (light). The heat of the flame is also converted into kinetic energy as the hot gasses rise.
Okay, basically, the fuel used is all potential energy, after the energy is transmitted to steam, the steam flows and moves turbines which transforms the potential energy of fuel to kinetic energy. :.)
endothermic energy
Thermal energy.
Thermal energy is regularly converted to electrical energy in power plants, as well as generators. Note that if some fuel (often fossil fuel) is used, the thermal energy is only an intermediate stage.
Any fuel will do.
The oil thermal plant refers to the chemical energy that is stored in the fossil fuel like the natural gas, oil shale, fuel oil, and coal. They are usually successively converted into thermal energy, mechanical energy, and electrical energy.

You generally need a catalyst or a mechanism to convert the energy. For example to convert fuel (a mass) into thermal energy, oxidizer and a spark are needed.
A match. Solid rocket fuel.
