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. Low dam is built across a stream






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






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






4. Steam with no water droplets






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






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






7. Use bowls basically to store sunlight






8. Low dam is built across a stream






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






10. Energy from heat contained in underground rocks






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






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






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






14. Energy from heat contained in underground rocks






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






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






17. Stores hydrogen above or below ground - very expensive






18. Corporate Average Fuel Economy






19. Department of Energy






20. Initial cost plus lifetime opperating cost






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






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






23. 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. Central retriever system that uses mirrors to collect heat






27. Stores hydrogen above or below ground - very expensive






28. Started at the end of the Age of Oil






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






30. Ocean Thermal Energy Conversion






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






32. Started at the end of the Age of Oil






33. Initial cost plus lifetime opperating cost






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






35. Mixture of steam and water droplets






36. Mixture of steam and water droplets






37. Organic material that can be used as fuels






38. Ocean Thermal Energy Conversion






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






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






41. Use of passive solar energy and solar cells






42. Department of Energy






43. 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
