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. Use of passive solar energy and solar cells






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






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

7. Steam with no water droplets






8. Mixture of steam and water droplets






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






10. Initial cost plus lifetime opperating cost






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






12. Central retriever system that uses mirrors to collect heat






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






14. Use bowls basically to store sunlight






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






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

25. Department of Energy






26. Energy from heat contained in underground rocks






27. Low dam is built across a stream






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






30. Started at the end of the Age of Oil






31. Energy from heat contained in underground rocks






32. Stores hydrogen above or below ground - very expensive






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






34. Organic material that can be used as fuels

36. Organic material that can be used as fuels






37. Ocean Thermal Energy Conversion






38. Corporate Average Fuel Economy






39. Steam with no water droplets






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






41. Use of passive solar energy and solar cells






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. Ocean Thermal Energy Conversion






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






45. Central retriever system that uses mirrors to collect heat






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