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. Steam with no water droplets






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






4. 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






5. Mixture of steam and water droplets






6. Mixture of steam and water droplets






7. Low dam is built across a stream






8. Central retriever system that uses mirrors to collect heat






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






10. Use bowls basically to store sunlight






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






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






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






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






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






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






17. Corporate Average Fuel Economy






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






19. Low dam is built across a stream






20. Energy from heat contained in underground rocks






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






22. Initial cost plus lifetime opperating cost






23. Use of passive solar energy and solar cells






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






25. Corporate Average Fuel Economy






26. Steam with no water droplets






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






28. Department of Energy






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






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






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






32. Initial cost plus lifetime opperating cost






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






34. Department of Energy






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






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






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






38. Ocean Thermal Energy Conversion






39. Stores hydrogen above or below ground - very expensive






40. Central retriever system that uses mirrors to collect heat






41. Stores hydrogen above or below ground - very expensive






42. Organic material that can be used as fuels






43. Ocean Thermal Energy Conversion






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






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






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






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