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






3. Mixture of steam and water droplets






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






5. Use of passive solar energy and solar cells






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






7. Use of passive solar energy and solar cells






8. Corporate Average Fuel Economy






9. Department of Energy






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






11. Central retriever system that uses mirrors to collect heat






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






13. Initial cost plus lifetime opperating cost






14. 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






15. Corporate Average Fuel Economy






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






17. Ocean Thermal Energy Conversion






18. Mixture of steam and water droplets






19. Organic material that can be used as fuels






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

22. Started at the end of the Age of Oil






23. Low dam is built across a stream






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






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






26. Stores hydrogen above or below ground - very expensive






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






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






29. Use bowls basically to store sunlight






30. Central retriever system that uses mirrors to collect heat






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






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






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






34. Initial cost plus lifetime opperating cost






35. Energy from heat contained in underground rocks






36. Ocean Thermal Energy Conversion






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






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






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






40. 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
