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






3. Energy from heat contained in underground rocks






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






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






6. Mixture of steam and water droplets






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






8. Organic material that can be used as fuels






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






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






11. Corporate Average Fuel Economy






12. Initial cost plus lifetime opperating cost






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






14. Department of Energy






15. Organic material that can be used as fuels






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






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






18. Stores hydrogen above or below ground - very expensive






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






20. Department of Energy






21. Central retriever system that uses mirrors to collect heat






22. Central retriever system that uses mirrors to collect heat






23. Use bowls basically to store sunlight






24. Initial cost plus lifetime opperating cost






25. Use of passive solar energy and solar cells






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






27. Stores hydrogen above or below ground - very expensive






28. 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






29. Ocean Thermal Energy Conversion






30. Started at the end of the Age of Oil






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






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






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






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






35. Steam with no water droplets






36. Mixture of steam and water droplets






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






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






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






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






41. Corporate Average Fuel Economy






42. Low dam is built across a stream






43. Started at the end of the Age of Oil






44. Use bowls basically to store sunlight






45. Steam with no water droplets
