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. Central retriever system that uses mirrors to collect heat






2. Initial cost plus lifetime opperating cost






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






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






5. Started at the end of the Age of Oil






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






7. Corporate Average Fuel Economy






8. 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






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






10. Energy from heat contained in underground rocks






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






12. Steam with no water droplets






13. Energy from heat contained in underground rocks






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






15. Use bowls basically to store sunlight






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






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






18. Department of Energy






19. Mixture of steam and water droplets






20. Stores hydrogen above or below ground - very expensive






21. Steam with no water droplets






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






23. Mixture of steam and water droplets






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






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






26. Initial cost plus lifetime opperating cost






27. Corporate Average Fuel Economy






28. Started at the end of the Age of Oil
