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. Distributed reciever system with sunlight collected and focused on pipes






2. Ocean Thermal Energy Conversion






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






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






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






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






7. Started at the end of the Age of Oil






8. Ocean Thermal Energy Conversion






9. Use of passive solar energy and solar cells






10. Mixture of steam and water droplets






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






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






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






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






15. Low dam is built across a stream






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






17. Department of Energy






18. Mixture of steam and water droplets






19. Steam with no water droplets






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






21. Central retriever system that uses mirrors to collect heat






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






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






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






25. Central retriever system that uses mirrors to collect heat






26. Started at the end of the Age of Oil






27. Use of passive solar energy and solar cells






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






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






30. Initial cost plus lifetime opperating cost






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






32. Corporate Average Fuel Economy






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






34. Use bowls basically to store sunlight






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






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






37. Steam with no water droplets






38. 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






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






40. Energy from heat contained in underground rocks






41. 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






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






43. Use bowls basically to store sunlight






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