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. Corporate Average Fuel Economy






2. Department of Energy






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






4. 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






5. Ocean Thermal Energy Conversion






6. Low dam is built across a stream






7. Use bowls basically to store sunlight






8. Organic material that can be used as fuels






9. Energy from heat contained in underground rocks






10. Initial cost plus lifetime opperating cost






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






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






13. Corporate Average Fuel Economy






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






15. Stores hydrogen above or below ground - very expensive






16. Initial cost plus lifetime opperating cost






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






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






19. Central retriever system that uses mirrors to collect heat






20. 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






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






22. Ocean Thermal Energy Conversion






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






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






25. Started at the end of the Age of Oil






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






27. Use bowls basically to store sunlight






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






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






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






31. Stores hydrogen above or below ground - very expensive






32. Organic material that can be used as fuels






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