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






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






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






4. Started at the end of the Age of Oil






5. Initial cost plus lifetime opperating cost






6. Central retriever system that uses mirrors to collect heat






7. Corporate Average Fuel Economy






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






9. Use bowls basically to store sunlight






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






11. Energy from heat contained in underground rocks






12. Organic material that can be used as fuels






13. Started at the end of the Age of Oil






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






15. Corporate Average Fuel Economy






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






17. Organic material that can be used as fuels






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. Stores hydrogen above or below ground - very expensive






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






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






22. Mixture of steam and water droplets






23. Steam with no water droplets






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






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






26. Mixture of steam and water droplets






27. Department of Energy






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






29. Energy from heat contained in underground rocks






30. Ocean Thermal Energy Conversion






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






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






33. Initial cost plus lifetime opperating cost






34. Low dam is built across a stream






35. Steam with no water droplets






36. Ocean Thermal Energy Conversion






37. Department of Energy






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






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






40. Low dam is built across a stream






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






42. 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






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






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






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






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