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. Organic material that can be used as fuels






2. Central retriever system that uses mirrors to collect heat






3. Low dam is built across a stream






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






5. Energy from heat contained in underground rocks






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






7. Steam with no water droplets






8. Central retriever system that uses mirrors to collect heat






9. 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






10. Use of passive solar energy and solar cells






11. Mixture of steam and water droplets






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






13. Ocean Thermal Energy Conversion






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






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






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






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






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






19. Stores hydrogen above or below ground - very expensive






20. Steam with no water droplets






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






22. Initial cost plus lifetime opperating cost






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






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






25. Mixture of steam and water droplets






26. 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






27. Initial cost plus lifetime opperating cost






28. Started at the end of the Age of Oil






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






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






31. Department of Energy






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






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






34. Corporate Average Fuel Economy






35. Use bowls basically to store sunlight






36. Organic material that can be used as fuels






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