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






2. Steam with no water droplets






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






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






5. Use of passive solar energy and solar cells






6. Stores hydrogen above or below ground - very expensive






7. Mixture of steam and water droplets






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






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






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






11. Organic material that can be used as fuels






12. Corporate Average Fuel Economy






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






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






15. Mixture of steam and water droplets






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






17. Department of Energy






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






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






20. Use bowls basically to store sunlight






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






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






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






24. Ocean Thermal Energy Conversion






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






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






27. Energy from heat contained in underground rocks






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






29. Ocean Thermal Energy Conversion






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






31. 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






32. Low dam is built across a stream






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






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






35. Central retriever system that uses mirrors to collect heat






36. Initial cost plus lifetime opperating cost






37. Started at the end of the Age of Oil






38. Use bowls basically to store sunlight






39. Central retriever system that uses mirrors to collect heat






40. Corporate Average Fuel Economy






41. Energy from heat contained in underground rocks






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






43. 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






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






45. Department of Energy






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






47. Low dam is built across a stream






48. Organic material that can be used as fuels






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