1. Food: The bonds within carbohydrates, fats, and proteins store chemical energy. When we eat, our bodies break these bonds and release the energy to fuel our activities.
2. Fossil fuels: Coal, oil, and natural gas are formed from the remains of ancient organisms. The chemical bonds within these fuels store large amounts of potential energy that is released when they are burned.
3. Batteries: Batteries contain chemicals that can react to release electrical energy. This electrical energy is a form of chemical energy stored as potential energy within the battery.
4. Wood: The cellulose and lignin in wood store chemical energy. When wood burns, this energy is released as heat and light.
