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






2. Organic material that can be used as fuels






3. Mixture of steam and water droplets






4. Stores hydrogen above or below ground - very expensive






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






6. Corporate Average Fuel Economy






7. Corporate Average Fuel Economy






8. Started at the end of the Age of Oil






9. Stores hydrogen above or below ground - very expensive






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






11. Central retriever system that uses mirrors to collect heat






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






13. Ocean Thermal Energy Conversion






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






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






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






17. Use of passive solar energy and solar cells






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






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






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. Initial cost plus lifetime opperating cost






22. Use of passive solar energy and solar cells






23. Use bowls basically to store sunlight






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






25. Steam with no water droplets






26. Ocean Thermal Energy Conversion






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






28. Use bowls basically to store sunlight






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






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






31. Energy from heat contained in underground rocks






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






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






34. 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






35. Mixture of steam and water droplets






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






37. Department of Energy






38. Initial cost plus lifetime opperating cost






39. Central retriever system that uses mirrors to collect heat






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