1. Sound Energy - In simple terms, sound energy comes from vibrations moving through something. Solids, liquids, and gases all transmit sound as energy waves. Sound energy is the result when a force, either sound or pressure, makes an object or substance vibrate.
2. Chemical Energy - How are food, fuel, and batteries alike? They are energy sources stored as chemical energy.
3. Heat Energy - can be used in agriculture in a number of ways, saving money, increasing self-reliance, and reducing pollution. Solar energy can cut a farm's electricity and heating bills. Solar heat collectors can be used to dry crops and warm homes, livestock buildings, and greenhouses.

5. Energy caused by changes in the nucleus of an atom - Electrical energy is the power an atom's charged particles have to cause an action or move an object. The movement of electrons from one atom to another is what results in electrical energy. Every time you plug a toaster or cellphone charger into a wall outlet, electrical energy is powering those devices.
