Presentation transcript:

Daily Review #3 6. Compare and contrast wind energy and photovoltaic energy. 7. Describe how electricity is created in a solar panel. 8. Describe how ethanol is created. 9. Would you install solar panels or a wind turbine on your house (in Colorado)? Why or why not?

Geothermal  Uses naturally hot air/water underground  Pump air/water to surface  Requires energy  Remove toxins  Creates steam  Spins turbines, turns generators  Cooler air/water pumped down  Process repeated  Reverse idea – air conditioning

Hydrogen  Separated from water  Using lots of electricity or sunlight  Creates moving electrons = electricity  Burned for energy  Fuel cells  Cars (more energy than gas)  Electricity  Clean  Storage issues

Daily Review #4 10. Compare and contrast solar energy and hydrogen fuel cells. 11. Describe how geothermal energy is created. 12. You are building a new house. What type of energy would you choose to power your house off of and why?
