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. Central retriever system that uses mirrors to collect heat






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






3. Energy from heat contained in underground rocks






4. Corporate Average Fuel Economy






5. Initial cost plus lifetime opperating cost






6. Mixture of steam and water droplets






7. Collectors absorb energy and a fan or pump supplies part of the building's space heating






8. Use of passive solar energy and solar cells






9. Absorbs and stores heat from the sun directly within a structure. Example is greenhouse






10. Corporate Average Fuel Economy






11. Initial cost plus lifetime opperating cost






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






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






14. Stores hydrogen above or below ground - very expensive






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






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

23. Energy from heat contained in underground rocks






24. Steam with no water droplets






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






26. 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






27. Mixture of steam and water droplets






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






29. Low dam is built across a stream






30. Department of Energy






31. Organic material that can be used as fuels
