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






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






3. Steam with no water droplets






4. 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






5. Use of passive solar energy and solar cells






6. Low dam is built across a stream






7. Started at the end of the Age of Oil






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






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






10. Use bowls basically to store sunlight






11. Organic material that can be used as fuels






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






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






14. Use of passive solar energy and solar cells






15. Corporate Average Fuel Economy






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






17. Energy from heat contained in underground rocks






18. Use bowls basically to store sunlight






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






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






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






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






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






24. Organic material that can be used as fuels






25. Low dam is built across a stream






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






27. Mixture of steam and water droplets






28. Initial cost plus lifetime opperating cost






29. 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






30. Ocean Thermal Energy Conversion






31. Mixture of steam and water droplets

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






36. Central retriever system that uses mirrors to collect heat






37. Department of Energy






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






39. Stores hydrogen above or below ground - very expensive






40. Steam with no water droplets






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