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






2. Low dam is built across a stream






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






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






5. Energy from heat contained in underground rocks






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






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






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






9. Use bowls basically to store sunlight






10. Corporate Average Fuel Economy






11. Stores hydrogen above or below ground - very expensive






12. Ocean Thermal Energy Conversion






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






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






15. Mixture of steam and water droplets






16. Use bowls basically to store sunlight






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






18. 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






19. Organic material that can be used as fuels






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






21. Low dam is built across a stream






22. Use of passive solar energy and solar cells






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






24. Steam with no water droplets






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






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






27. Corporate Average Fuel Economy






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






29. Ocean Thermal Energy Conversion






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






31. Organic material that can be used as fuels






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






33. Use of passive solar energy and solar cells






34. Stores hydrogen above or below ground - very expensive






35. Started at the end of the Age of Oil






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






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






38. Department of Energy






39. Steam with no water droplets






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






41. 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






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






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






44. Initial cost plus lifetime opperating cost






45. Started at the end of the Age of Oil
