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. Department of Energy






2. Department of Energy






3. Central retriever system that uses mirrors to collect heat






4. Energy from heat contained in underground rocks






5. Mixture of steam and water droplets






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






7. Use bowls basically to store sunlight






8. Started at the end of the Age of Oil






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






10. Initial cost plus lifetime opperating cost






11. Energy from heat contained in underground rocks






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






13. Use of passive solar energy and solar cells






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






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






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






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






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






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






20. Steam with no water droplets






21. Organic material that can be used as fuels






22. Initial cost plus lifetime opperating cost






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






24. Use bowls basically to store sunlight






25. Organic material that can be used as fuels






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






27. 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






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






29. Stores hydrogen above or below ground - very expensive






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






31. Low dam is built across a stream






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






33. Mixture of steam and water droplets






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. Ocean Thermal Energy Conversion






36. Steam with no water droplets






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






38. Ocean Thermal Energy Conversion






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






40. Started at the end of the Age of Oil






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






42. Use of passive solar energy and solar cells






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






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






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






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