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. Use of passive solar energy and solar cells






3. Mixture of steam and water droplets






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






5. Use bowls basically to store sunlight






6. 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






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






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






9. Initial cost plus lifetime opperating cost






10. Central retriever system that uses mirrors to collect heat






11. Low dam is built across a stream






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






13. 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






14. Steam with no water droplets






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






16. Stores hydrogen above or below ground - very expensive






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






18. Steam with no water droplets






19. Ocean Thermal Energy Conversion






20. Started at the end of the Age of Oil






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






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






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






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






25. Use of passive solar energy and solar cells






26. Energy from heat contained in underground rocks






27. Initial cost plus lifetime opperating cost






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






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






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






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






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






33. Mixture of steam and water droplets






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






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






36. Ocean Thermal Energy Conversion






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






38. Low dam is built across a stream






39. Started at the end of the Age of Oil






40. Corporate Average Fuel Economy






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






42. Department of Energy






43. Organic material that can be used as fuels






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






45. Corporate Average Fuel Economy
