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






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






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






4. Ocean Thermal Energy Conversion






5. Use of passive solar energy and solar cells






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






7. Corporate Average Fuel Economy






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






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






10. 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






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






12. Low dam is built across a stream






13. Initial cost plus lifetime opperating cost






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






15. Mixture of steam and water droplets






16. Initial cost plus lifetime opperating cost






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






18. 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






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






20. Stores hydrogen above or below ground - very expensive






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






22. Ocean Thermal Energy Conversion






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






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






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






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






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






28. Use of passive solar energy and solar cells






29. Energy from heat contained in underground rocks






30. Use bowls basically to store sunlight

32. Use bowls basically to store sunlight






33. Steam with no water droplets






34. Organic material that can be used as fuels






35. Corporate Average Fuel Economy






36. Started at the end of the Age of Oil






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






38. Steam with no water droplets






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






40. Mixture of steam and water droplets
