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






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






4. Energy from heat contained in underground rocks






5. Started at the end of the Age of Oil






6. Steam with no water droplets






7. 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






8. Steam with no water droplets






9. Stores hydrogen above or below ground - very expensive






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. Corporate Average Fuel Economy






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






14. Mixture of steam and water droplets






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






16. Department of Energy






17. 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






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






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






20. Ocean Thermal Energy Conversion






21. Use bowls basically to store sunlight






22. Mixture of steam and water droplets






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






24. Energy from heat contained in underground rocks






25. Stores hydrogen above or below ground - very expensive






26. Low dam is built across a stream






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






28. Low dam is built across a stream






29. Corporate Average Fuel Economy






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

33. Department of Energy






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






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






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






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






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






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






40. Central retriever system that uses mirrors to collect heat






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






42. Initial cost plus lifetime opperating cost






43. Ocean Thermal Energy Conversion






44. Use of passive solar energy and solar cells






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