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






2. Corporate Average Fuel Economy






3. Use bowls basically to store sunlight






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






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






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






7. Department of Energy






8. Use of passive solar energy and solar cells






9. 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






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






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






14. Started at the end of the Age of Oil






15. Steam with no water droplets






16. Energy from heat contained in underground rocks






17. Low dam is built across a stream






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






19. Low dam is built across a stream






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






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






22. Use bowls basically to store sunlight






23. Central retriever system that uses mirrors to collect heat






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






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






26. Department of Energy






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






28. Energy from heat contained in underground rocks






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






30. Ocean Thermal Energy Conversion






31. Organic material that can be used as fuels






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






33. Initial cost plus lifetime opperating cost






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. Central retriever system that uses mirrors to collect heat






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






37. Corporate Average Fuel Economy






38. Organic material that can be used as fuels






39. Mixture of steam and water droplets






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






41. Mixture of steam and water droplets






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






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






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






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






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






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






48. Stores hydrogen above or below ground - very expensive






49. Use of passive solar energy and solar cells






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