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






2. 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






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






4. Energy from heat contained in underground rocks






5. Mixture of steam and water droplets






6. Corporate Average Fuel Economy






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






8. Department of Energy






9. Ocean Thermal Energy Conversion






10. Use of passive solar energy and solar cells






11. Low dam is built across a stream






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






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






14. Organic material that can be used as fuels






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






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






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






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






19. Use bowls basically to store sunlight






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. Central retriever system that uses mirrors to collect heat






22. Initial cost plus lifetime opperating cost






23. Central retriever system that uses mirrors to collect heat






24. Energy from heat contained in underground rocks






25. Department of Energy






26. Steam with no water droplets






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






28. Mixture of steam and water droplets






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






30. Low dam is built across a stream






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






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






33. Use bowls basically to store sunlight






34. Ocean Thermal Energy Conversion






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






36. Initial cost plus lifetime opperating cost






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






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






39. Started at the end of the Age of Oil






40. Stores hydrogen above or below ground - very expensive






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






42. Corporate Average Fuel Economy






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






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






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






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






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






48. Started at the end of the Age of Oil






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






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