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. Steam with no water droplets






2. Use of passive solar energy and solar cells






3. Ocean Thermal Energy Conversion






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






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






6. Department of Energy






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






8. Corporate Average Fuel Economy






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






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






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






12. Central retriever system that uses mirrors to collect heat






13. Use bowls basically to store sunlight






14. Energy from heat contained in underground rocks






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






16. Low dam is built across a stream






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






18. Central retriever system that uses mirrors to collect heat






19. Department of Energy






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






21. Mixture of steam and water droplets






22. Started at the end of the Age of Oil






23. Steam with no water droplets






24. Started at the end of the Age of Oil






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






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






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






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






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






30. Initial cost plus lifetime opperating cost






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






32. Ocean Thermal Energy Conversion






33. 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






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






35. Low dam is built across a stream






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






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






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






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






40. Initial cost plus lifetime opperating cost






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






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






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






44. Stores hydrogen above or below ground - very expensive






45. Mixture of steam and water droplets






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






47. Corporate Average Fuel Economy






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






49. Organic material that can be used as fuels






50. Use of passive solar energy and solar cells
