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. Organic material that can be used as fuels






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






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






4. Central retriever system that uses mirrors to collect heat






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






6. Ocean Thermal Energy Conversion






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






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






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






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






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






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






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






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






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






16. Initial cost plus lifetime opperating cost






17. Steam with no water droplets






18. Stores hydrogen above or below ground - very expensive






19. Organic material that can be used as fuels






20. Department of Energy






21. Energy from heat contained in underground rocks






22. Initial cost plus lifetime opperating cost






23. Mixture of steam and water droplets






24. Use bowls basically to store sunlight






25. Stores hydrogen above or below ground - very expensive






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






27. Central retriever system that uses mirrors to collect heat






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






29. Low dam is built across a stream






30. Started at the end of the Age of Oil






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






32. 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






33. Use bowls basically to store sunlight






34. Steam with no water droplets






35. Use of passive solar energy and solar cells






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






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






38. Use of passive solar energy and solar cells






39. Department of Energy






40. Corporate Average Fuel Economy






41. Mixture of steam and water droplets






42. 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






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






44. Energy from heat contained in underground rocks






45. Corporate Average Fuel Economy






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






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






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






49. Started at the end of the Age of Oil






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