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






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






3. Steam with no water droplets






4. Started at the end of the Age of Oil






5. Corporate Average Fuel Economy






6. Corporate Average Fuel Economy






7. Low dam is built across a stream






8. Steam with no water droplets






9. Mixture of steam and water droplets






10. Department of Energy






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






12. Energy from heat contained in underground rocks






13. Ocean Thermal Energy Conversion






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






15. Use of passive solar energy and solar cells






16. Use bowls basically to store sunlight






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






18. Use bowls basically to store sunlight






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






20. Central retriever system that uses mirrors to collect heat






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






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






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






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






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






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






27. Use of passive solar energy and solar cells






28. Stores hydrogen above or below ground - very expensive






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






30. Mixture of steam and water droplets






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






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






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






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






35. Energy from heat contained in underground rocks






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






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






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. Central retriever system that uses mirrors to collect heat






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






41. Low dam is built across a stream






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






43. Started at the end of the Age of Oil
