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. Initial cost plus lifetime opperating cost






2. Low dam is built across a stream






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

16. Organic material that can be used as fuels






17. Central retriever system that uses mirrors to collect heat






18. Department of Energy






19. Energy from heat contained in underground rocks






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






21. Stores hydrogen above or below ground - very expensive






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






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






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

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






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






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






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






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






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

33. Mixture of steam and water droplets






34. Organic material that can be used as fuels






35. Steam with no water droplets






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






37. Initial cost plus lifetime opperating cost






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






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






40. Energy from heat contained in underground rocks






41. Ocean Thermal Energy Conversion






42. 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






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






44. Use of passive solar energy and solar cells






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