4. The ability to do work or cause change.
5. Energy of motion.
7. Energy cannot be created or destroyed, it can only change forms (transformed).
8. Closed path where electrons can flow.
13. The energy stored in an object because of its position or composition.
15. A machine that converts mechanical energy into electrical energy.
19. Type of electricity that needs a circuit.
20. The potential energy stored in the nucleus of an atom.

1. Type of electricity found in nature.
2. Energy that is limited and emits greenhouse gases.
3. A form of potential energy that is stored in chemical bonds between atoms.
4. Made of metal and electricity.
6. A change from one form of energy to another.
9. Example of a renewable resource which uses the flow of moving water to generate electricity.
10. Energy that is unlimited and emits lower greenhouse gases.
11. Form of kinetic energy carried by sound waves.
12. Kinetic or potential energy associated with the motion or position of an object.
14. Form of energy that is kinetic and is caused by the movement of electrons.
16. A force caused by the spinning of electrons in the same direction around the nucleus.
17. Form of energy that is kinetic and is due to the motion in the particles of a substance. Is related to temperature.
18. Form of energy that is kinetic and is carried by electromagnetic waves. Has to do with light.
21. Example of a non-renewable resource used to produce most of U.S. electricity.
