Energy Efficiency And Renewable Energy Revolution

Subject : science
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Where hydrogen and oxygen are combined to produce electrical currents - have no moving parts - are quiet - only emit water or heat - and are more reliable






2. Mixture of steam and water droplets






3. Organic material that can be used as fuels






4. Energy of the entire delivery process - determined by efficiency of each step of the procedure






5. Initial cost plus lifetime opperating cost






6. Corporate Average Fuel Economy






7. Dam is built across a large river to create a resevoir - uses turbines






8. The percentage of total input into a conversion device or system that does useful work and is not converted to useless heat






9. Started at the end of the Age of Oil






10. Low dam is built across a stream






11. Ocean Thermal Energy Conversion






12. Energy of the entire delivery process - determined by efficiency of each step of the procedure






13. Central retriever system that uses mirrors to collect heat






14. Distributed reciever system with sunlight collected and focused on pipes






15. Started at the end of the Age of Oil






16. Dam is built across a large river to create a resevoir - uses turbines






17. Corporate Average Fuel Economy






18. Initial cost plus lifetime opperating cost






19. Photovoltaic cells - or solar cells. Transparent wafer with a semiconductor material hanging and creates an electrical current






20. Homes with walls made of bales covered with plaster or adobe






21. Department of Energy






22. Produces hydrogen by using chemical processes and high temperatures to seperate hydrogen atoms from carbon






23. Energy from heat contained in underground rocks






24. Central retriever system that uses mirrors to collect heat






25. Organic material that can be used as fuels






26. Stores hydrogen above or below ground - very expensive






27. Combined heat and power CHP - two useful materials are produced from the same fuel source.






28. Collect and transform radiant energy from the sun into thermal energy that can be converted to electricity






29. Pumps using surplus electricity from a powerplant pump water from one lake to another
