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.

11. Use of passive solar energy and solar cells






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






13. Low dam is built across a stream






14. Use bowls basically to store sunlight






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






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






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

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






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






24. 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






25. Ocean Thermal Energy Conversion






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






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






28. Stores hydrogen above or below ground - very expensive






29. Started at the end of the Age of Oil






30. 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






31. Stores hydrogen above or below ground - very expensive






32. Low dam is built across a stream
