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. Use of passive solar energy and solar cells






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






3. Energy from heat contained in underground rocks






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






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






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






7. Organic material that can be used as fuels






8. Central retriever system that uses mirrors to collect heat






9. Use bowls basically to store sunlight






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






11. Use bowls basically to store sunlight






12. Steam with no water droplets






13. Corporate Average Fuel Economy






14. Department of Energy






15. Corporate Average Fuel Economy






16. Central retriever system that uses mirrors to collect heat






17. Steam with no water droplets






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






19. Mixture of steam and water droplets






20. Low dam is built across a stream






21. Stores hydrogen above or below ground - very expensive






22. Initial cost plus lifetime opperating cost






23. Started at the end of the Age of Oil






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






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






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






27. Started at the end of the Age of Oil






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






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






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






31. Energy from heat contained in underground rocks






32. Low dam is built across a stream






33. Department of Energy






34. Organic material that can be used as fuels






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






36. Initial cost plus lifetime opperating cost






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






38. Use of passive solar energy and solar cells






39. Ocean Thermal Energy Conversion






40. Stores hydrogen above or below ground - very expensive






41. 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






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






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






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






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






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






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






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






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






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