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. Ocean Thermal Energy Conversion






2. Use bowls basically to store sunlight






3. Initial cost plus lifetime opperating cost






4. Low dam is built across a stream






5. Stores hydrogen above or below ground - very expensive






6. 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






7. Use bowls basically to store sunlight






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






9. Organic material that can be used as fuels






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






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






12. Use of passive solar energy and solar cells






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






14. Organic material that can be used as fuels






15. Stores hydrogen above or below ground - very expensive






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






17. Corporate Average Fuel Economy






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






19. The percentage of total input into a conversion device or system that does useful work and is not converted to useless 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. Homes with walls made of bales covered with plaster or adobe






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