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






2. Department of Energy






3. Started at the end of the Age of Oil






4. Ocean Thermal Energy Conversion






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






6. Use of passive solar energy and solar cells






7. 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






8. Stores hydrogen above or below ground - very expensive






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






10. Ocean Thermal Energy Conversion






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






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






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






14. Initial cost plus lifetime opperating cost






15. Mixture of steam and water droplets






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






17. 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






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






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






20. Organic material that can be used as fuels






21. Energy from heat contained in underground rocks






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






23. Use bowls basically to store sunlight






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






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






26. Corporate Average Fuel Economy






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






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






29. Stores hydrogen above or below ground - very expensive






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






31. Mixture of steam and water droplets






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






33. Use of passive solar energy and solar cells






34. Department of Energy






35. Low dam is built across a stream

37. Central retriever system that uses mirrors to collect heat






38. Central retriever system that uses mirrors to collect heat






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






40. Initial cost plus lifetime opperating cost






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






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






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






44. Low dam is built across a stream
