2. 1.) More and more people are using wind power to produce energy to heat and cool their homes. Wind power is— Aa nonrenewable resource that formed during the time of the dinosaurs Ban alternative resource that formed from the remains of dead plants and animals Ca renewable resource that forms as trees grow larger and larger on Earth’s surface Dan alternative energy resource that forms due to the uneven heating of the Earth by the sun

3. 2.) What does the above illustration show? Athe capture of wind energy Bthe collection of solar energy Cthe conversion of water power into electricity Dthe use of fossil fuels to operate a windmill

4. 3.) Natural resources are needed to produce the energy needed for many of our daily activities. Some of our energy comes from fossil fuel sources while the rest is developed from alternative energy sources. How does oil compare to biomass? A Oil is a fossil fuel and biomass is an alternative energy source B Oil is an alternative energy source and biomass is a fossil fuel C They are both alternative energy sources D They are both fossil fuels

5. 4.) Why do most scientists feel that we need to better explore the use of alternative energy sources? AWe are using fossil fuels slower than they can be replaced. BWe are using fossil fuels much slower than expected. CWe are using fossil fuels faster than they can be replaced. DWe are not using enough fossil fuels in the world today.

6. 5.) Geothermal energy has been around as long as the Earth has existed. The ancient Romans and the Japanese have long used geothermal energy for bathing and relaxation. Geothermal energy is a type of— Aheat energy Belectrical energy Csolar energy Dchemical energy

7. 6.) Which of the following is an example of biomass? AA tomato plant BManure CA pine tree DAll of the above

8. 7.) Many cities are taking actions to cause less harm to the environment. Which action produces energy from an alternative source? A Burning coal to heat homes B Replacing lawns with plants that require less water C Using biofuels to generate electricity D Building a new water-treatment plant to improve water quality

9. Read the following and then answer the question. 8.) The energy in ethanol originated from – A thermal energy B light energy C sound energy D mechanical energy

10. The Hoover Dam is located on the border between Arizona and Nevada. It produces hydroelectricity which provides power to parts of Arizona, Nevada, and California. 9.) Which of the following is used to produce hydroelectricity? A burning coal B moving air currents C moving water D heat from within the Earth

11. 10.) All of the following will help reduce the use of fossil fuels EXCEPT – A driving an electric car B generating electricity at a hydroelectric power plant C using solar energy to power the appliances in a house D driving a gasoline powered car more frequently

12. 11.) A wind farm contains a large number of wind turbines that are used to generate electricity. Which is the best reason wind farms are not located near forests? A The wind turbines would destroy the trees of the forest. B The electricity would be too far away from homes to be useful. C Forest animals would destroy the wind turbines. D The trees in the forest would block some of the wind making the wind farm less productive.

13. 12.) This power plant produces electricity most likely by using — A fossil fuels B biofuels C solar energy D geothermal energy
