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






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






4. Stores hydrogen above or below ground - very expensive






5. Ocean Thermal Energy Conversion






6. Low dam is built across a stream






7. Stores hydrogen above or below ground - very expensive






8. Energy from heat contained in underground rocks






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






10. Use bowls basically to store sunlight






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






12. Steam with no water droplets






13. Steam with no water droplets






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






15. Corporate Average Fuel Economy






16. Initial cost plus lifetime opperating cost






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






18. Department of Energy






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






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






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






22. Use bowls basically to store sunlight






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






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






25. 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






26. Ocean Thermal Energy Conversion






27. Mixture of steam and water droplets






28. 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






29. Corporate Average Fuel Economy






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

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






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






34. Central retriever system that uses mirrors to collect heat






35. Organic material that can be used as fuels






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






37. Use of passive solar energy and solar cells






38. Use of passive solar energy and solar cells






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






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






41. Central retriever system that uses mirrors to collect heat






42. Initial cost plus lifetime opperating cost






43. Department of Energy
