What is chemical energy?

This reaction results in new chemical bonds of carbon dioxide, carbon monoxide and water. As it burns in the fireplace, chemical energy is released and converted to thermal energy (heat) and light energy. Notice that the wood now turns into ashes (a new substance) Food is also a good example of stored chemical energy.
