The energy released from burning organic material comes from the chemical bonds within the molecules of the material. When these bonds are broken during combustion, it releases heat and light energy. The primary source of this energy is usually stored in the form of carbon-based molecules like carbohydrates, fats, and proteins.

Burning organic material releases heat energy in the form of thermal energy. This process occurs through combustion, where the organic matter reacts with oxygen to produce heat and light energy.
Burning typically produces thermal energy, also known as heat energy. This process involves the conversion of stored chemical energy in a material into heat and light energy as the material combusts and reacts with oxygen.
Organic material can be broken down by microorganisms to create compost, which is a nutrient-rich soil amendment used in gardening. Another product of organic material decomposition is biogas, which can be used as a renewable energy source for heating and electricity generation.
A fuel is a material that, when burned or reacted with oxygen, releases energy. Fuels typically come from organic sources like plants or animals (biofuels) or from fossilized organic matter like coal, oil, and natural gas. The energy released from burning fuels is used to power vehicles, generate electricity, and heat homes and buildings.
Burning wood chemically alters its composition, causing it to release heat and light energy as the organic material decomposes into carbon dioxide, water vapor, and ashes. This process is known as combustion, and it transforms the physical and chemical nature of the wood, reducing it to a charred residue.
