Energy Efficiency And Renewable Energy Revolution

Subject : science
Instructions:
  • Answer 50 questions in 30 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. Dam is built across a large river to create a resevoir - uses turbines






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






3. Corporate Average Fuel Economy






4. Central retriever system that uses mirrors to collect heat






5. Use bowls basically to store sunlight






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






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






8. Steam with no water droplets






9. Mixture of steam and water droplets






10. 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






11. Initial cost plus lifetime opperating cost






12. Stores hydrogen above or below ground - very expensive






13. Use of passive solar energy and solar cells






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






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






16. Use bowls basically to store sunlight






17. Low dam is built across a stream






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






19. Started at the end of the Age of Oil
