Fossil fuels can be burned to release the potential chemical energy stored millions of years ago.The process of burning fuels is called Combustion.
Chemical energy is contained in the bonds between atoms within molecules. When these bonds are broken or rearranged during a chemical reaction, energy is released or absorbed. Examples include the energy stored in food molecules like glucose and in fossil fuels like gasoline.
Three forms of stored energy are mechanical energy (e.g. in springs or compressed air), chemical energy (e.g. in batteries or fossil fuels), and gravitational potential energy (e.g. in raised objects).
The chemical reaction that creates energy from the digested food, after the food has been absorbed into the body, is called the Kreb's Cycle. It is a series of chemical reactions that converts carbohydrates, proteins, fats, and alcohol into the very basic energy molecule called ATP.
Chemical energy in my book is that released by combustion of fuels such as coal and oil and natural gas. The benefits of this are electricity, home heating, cooking, and transport, and you can probably think of others.
Yes, the type of energy stored by fossil fuels such as coal is chemical potential energy. This energy is released when the fossil fuel is burned and chemical reactions occur, resulting in the production of heat and other forms of energy such as electricity.
Potential
Fossil fuels like coal store potential energy in the form of chemical bonds. When they are burned, this potential energy is converted into heat energy (thermal energy) and released as a result of chemical reactions taking place. Kinetic energy is the energy of motion, and while there may be kinetic energy involved in the burning process (e.g., moving particles in the flame), the primary form of energy stored in fossil fuels is potential energy.
Fossil fuels represent chemical energy, a form of potential energy. This energy was stored in the hydrocarbon molecules and can be released by oxidation (burning).

Fossil fuels are formed from organic matter that originally obtained its energy from the sun through photosynthesis. This organic matter stored the sun's energy in the form of chemical bonds, which is released as chemical energy when the fossil fuels are burned. So, the chemical energy in fossil fuels can be traced back to the sun's energy.
When fossil fuels are burned, they undergo a chemical reaction with oxygen in the air to release heat energy. This process breaks the chemical bonds within the fossil fuels, resulting in the release of stored potential energy in the form of heat.

chemical energy
Potential energy, which is stored as chemical bonds in the hydrocarbon molecules.
I would actually describe the energy as chemical, as the energy is being used to hold the chemical bonds of the hydrocarbons together. But it is certainly not kinetic, so give these two choices the answer is potential. It is potential energy waiting for a chemical reaction.
