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






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






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






5. Department of Energy






6. Energy from heat contained in underground rocks






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






8. Started at the end of the Age of Oil






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






10. Stores hydrogen above or below ground - very expensive






11. Low dam is built across a stream






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






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






14. Corporate Average Fuel Economy






15. Initial cost plus lifetime opperating cost






16. Mixture of steam and water droplets






17. Ocean Thermal Energy Conversion






18. Energy from heat contained in underground rocks






19. Steam with no water droplets






20. Organic material that can be used as fuels






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






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






23. 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






24. Low dam is built across a stream






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






26. Initial cost plus lifetime opperating cost






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






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






29. Ocean Thermal Energy Conversion






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






31. Use of passive solar energy and solar cells






32. Central retriever system that uses mirrors to collect heat






33. Started at the end of the Age of Oil






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






35. 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






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






37. Department of Energy






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






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






40. Organic material that can be used as fuels






41. Use of passive solar energy and solar cells
