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






2. Stores hydrogen above or below ground - very expensive






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






4. Mixture of steam and water droplets






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






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






7. Central retriever system that uses mirrors to collect heat






8. Mixture of steam and water droplets






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






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






11. Started at the end of the Age of Oil






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






13. Use of passive solar energy and solar cells






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






15. Low dam is built across a stream






16. Use of passive solar energy and solar cells






17. Corporate Average Fuel Economy






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






19. Ocean Thermal Energy Conversion






20. Steam with no water droplets






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






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






23. Initial cost plus lifetime opperating cost






24. Corporate Average Fuel Economy






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






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






27. Initial cost plus lifetime opperating cost






28. Use bowls basically to store sunlight






29. Ocean Thermal Energy Conversion






30. Steam with no water droplets






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. Distributed reciever system with sunlight collected and focused on pipes






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






34. 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






35. Energy from heat contained in underground rocks






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






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






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






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






40. Organic material that can be used as fuels






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






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






43. Use bowls basically to store sunlight






44. Department of Energy






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






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