1. Produces electricity and heat

2. Most used renewable resource in the United States

3. Environmental Impact - High startup cost - Low efficiency in some cases

4. Time - heat - pressure

5. What country leads the world in wind energy generating?

6. Secondary Pollution (Toxic materials and alcohols - Blocking the sun for some animals - No direct pollution though!) - Bird death ray - Startup cost

7. Most used energy source in the united states

8. Lowest rank of coal

9. Pockets of hot water or steam underground

10. Where the most Geothermal Energy is produced in all of the United States

11. Burning wood
