2. ENERGY The ability to do work.

3. Renewable Renewable - sources that can be replenished in a short period of time. Solar, Wind, Hydropower, Geothermal, Biomass

4. Nonrenewable Nonrenewable - come out of the ground as liquids, gases and solids and cannot be replenished in a short period of time Petroleum (Oil), Coal, Natural Gas, Uranium (nuclear), & Propane

5. Potential Energy Energy an object has due to place or position. Stored energy is POTENTIAL ENERGY.

6. Kinetic Energy The energy of an object or substance in movement. Anything in motion (an object, or sound, light, or electricity) has KINETIC ENERGY.

7. Electrical energy The energy of electrons moving or flowing within a substance. The energy of an electrical current (moving electrons). Renewable

8. NUCLEAR ENERGY Energy stored in the nucleus of an atom that holds an atom together; sometimes called atomic energy Nonrenewable

9. Chemical Energy Energy stored in the chemical bonds between atoms and molecules. Can be renewable (if the sources is renewable) or non-renewable (if source cannot be replaced easily, like oil and gas).

10. Radiant or Light Energy Electromagnetic energy that travels in waves, such as light rays from the sun. Other radiant energy: microwaves, x-rays, infrared radiation, gamma rays. Renewable

11. PETROLEUM Oil or crude oil; a liquid fossil fuel formed from the remains of prehistoric plants and animals Nonrenewable

12. COAL Coal is a readily combustible black or brownish-black fossil fuel sedimentary rock that is used for generating electricity. Make sure you are drawing the pictures! Nonrenewable

13. NATURAL GAS Natural gas is a colorless, odorless mixture of gases that formed from the fossil remains of ancient plants and animals buried deep in the earth (fossil fuel). Main ingredient = Methane. Gas stove Nonrenewable

14. URANIUM Uranium is a radioactive, metal found in rocks all over the world. Used to make nuclear energy. (During nuclear fission, a small particle called a neutron hits the uranium atom and splits it, releasing a great amount of energy as heat and radiation) Nonrenewable

15. Sound Energy Energy that moves through substances by compression waves. Sound waves are an example of kinetic energy. Renewable

16. Thermal Energy The internal energy of a substance due to random vibration and movement of its atoms and molecules. “Internal heat” due to movement of particles in a substance. Renewable

17. PROPANE Propane is an energy-rich gas that is found mixed with natural gas and oil Nonrenewable

18. SOLAR Solar energy is energy from the sun’s rays (solar radiation) that reach the earth. Renewable

19. WIND The circulation of air caused by the uneven heating of the earth’s surface; air in motion Renewable

20. HYDROPOWER Hydropower is energy from the force of moving water caused by gravity. Sources include the ocean, rivers, and waterfalls. Renewable

21. GEOTHERMAL Geothermal energy is heat from within the earth. Geo = earth and thermal = heat. Renewable

22. BIOMASS or BIOENERGY Biomass energy is energy made by burning biomass - organic material made from plants and animal waste. Biomass contains stored energy from the sun. Renewable
