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






2. Initial cost plus lifetime opperating cost






3. Department of Energy






4. Organic material that can be used as fuels






5. Use of passive solar energy and solar cells






6. Steam with no water droplets






7. Initial cost plus lifetime opperating cost






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






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






10. 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






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






12. Started at the end of the Age of Oil






13. Ocean Thermal Energy Conversion






14. Ocean Thermal Energy Conversion






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






16. Steam with no water droplets






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






18. Organic material that can be used as fuels






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






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






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






22. Mixture of steam and water droplets






23. Mixture of steam and water droplets






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






25. Use bowls basically to store sunlight






26. Use bowls basically to store sunlight






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






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






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






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






31. Energy from heat contained in underground rocks






32. Central retriever system that uses mirrors to collect heat






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






34. Low dam is built across a stream






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






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






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






38. Energy from heat contained in underground rocks






39. Central retriever system that uses mirrors to collect heat






40. Started at the end of the Age of Oil






41. Low dam is built across a stream






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






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






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






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






46. 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






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






48. Stores hydrogen above or below ground - very expensive






49. Department of Energy






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