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






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






3. Use bowls basically to store sunlight






4. Use of passive solar energy and solar cells






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






6. Stores hydrogen above or below ground - very expensive






7. Energy from heat contained in underground rocks






8. Initial cost plus lifetime opperating cost






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






10. Stores hydrogen above or below ground - very expensive






11. Central retriever system that uses mirrors to collect heat






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






13. Low dam is built across a stream






14. Organic material that can be used as fuels






15. Ocean Thermal Energy Conversion






16. Steam with no water droplets






17. 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






18. Initial cost plus lifetime opperating cost






19. Department of Energy






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






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






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






23. Organic material that can be used as fuels






24. Mixture of steam and water droplets






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






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






27. Low dam is built across a stream






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






29. Steam with no water droplets






30. Mixture of steam and water droplets






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






32. Corporate Average Fuel Economy






33. Ocean Thermal Energy Conversion






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






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






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






37. Central retriever system that uses mirrors to collect heat






38. Energy from heat contained in underground rocks






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






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






41. Started at the end of the Age of Oil






42. Department of Energy






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






44. Corporate Average Fuel Economy






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






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






47. Started at the end of the Age of Oil






48. Use bowls basically to store sunlight






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






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