1. Food: The food we eat contains chemical energy stored in the bonds of molecules like carbohydrates, fats, and proteins. When we digest food, our bodies break these bonds, releasing the energy to power our bodies.

2. Batteries: Batteries store chemical energy in the form of chemical reactions between their internal components. When you connect a battery to a device, these reactions occur, releasing the stored energy as electrical energy. This is why batteries power things like phones, laptops, and flashlights.
