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






2. Mixture of steam and water droplets






3. Low dam is built across a stream






4. Initial cost plus lifetime opperating cost

6. Initial cost plus lifetime opperating cost






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






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






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






10. Low dam is built across a stream






11. Corporate Average Fuel Economy






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






13. Started at the end of the Age of Oil






14. Central retriever system that uses mirrors to collect heat






15. Energy from heat contained in underground rocks






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






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






18. Stores hydrogen above or below ground - very expensive






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






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






21. Use bowls basically to store sunlight






22. Steam with no water droplets






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






24. Use of passive solar energy and solar cells






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






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






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






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






29. Organic material that can be used as fuels






30. Use of passive solar energy and solar cells






31. Organic material that can be used as fuels






32. Department of Energy






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






34. Central retriever system that uses mirrors to collect heat






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






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






37. Started at the end of the Age of Oil






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






39. 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






40. Use bowls basically to store sunlight






41. Steam with no water droplets






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






43. 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






44. Stores hydrogen above or below ground - very expensive






45. Department of Energy






46. Corporate Average Fuel Economy






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






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






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






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