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. Stores hydrogen above or below ground - very expensive






2. Mixture of steam and water droplets






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






4. Use of passive solar energy and solar cells






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






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






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






8. Corporate Average Fuel Economy






9. Initial cost plus lifetime opperating cost






10. Low dam is built across a stream






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






12. Use bowls basically to store sunlight






13. Started at the end of the Age of Oil






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






15. Department of Energy






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






17. 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






18. Steam with no water droplets






19. Stores hydrogen above or below ground - very expensive






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






21. Low dam is built across a stream






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






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






24. Energy from heat contained in underground rocks






25. Use bowls basically to store sunlight






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






27. Energy efficient smaller technology to be used in every day life






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






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






30. Started at the end of the Age of Oil






31. Initial cost plus lifetime opperating cost






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






33. Use of passive solar energy and solar cells
