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






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






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






4. Use of passive solar energy and solar cells






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






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






9. Steam with no water droplets






10. Corporate Average Fuel Economy






11. Started at the end of the Age of Oil






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






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






14. Use bowls basically to store sunlight






15. Energy from heat contained in underground rocks






16. Initial cost plus lifetime opperating cost






17. Central retriever system that uses mirrors to collect heat






18. Started at the end of the Age of Oil






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






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






21. 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






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






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






24. Organic material that can be used as fuels






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






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






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






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






29. Corporate Average Fuel Economy






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






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






32. Mixture of steam and water droplets






33. Low dam is built across a stream






34. Organic material that can be used as fuels






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






36. Energy from heat contained in underground rocks






37. Stores hydrogen above or below ground - very expensive






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