The law of conservation of energy is applied to the burning of fossil fuels because the energy of the fuels changes its form while burning.
How do you explain the law of conservation of energy?
The low of conservation of energy states that energy can only change its form from one to another. Energy can not be created or destroyed.
For energy production, fossil fuels are burned. They burned in the presence of oxygen. Hence at the time of burning, a chemical reaction takes place and the energy of the fuel is conserved into heat energy.
Let's take an example, a lump of coal is burned and a chemical reaction takes place. The carbon atoms present in the coal are converted into carbon dioxide. Hence the energy inside the coal changes its form.
Hence we can conclude that as per the law of conservation of energy, the energy of fossil fuels changes its form while burning and the total energy is conserved.
