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. Low dam is built across a stream






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






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






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






6. 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






7. Energy from heat contained in underground rocks






8. Use of passive solar energy and solar cells






9. Organic material that can be used as fuels






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






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






12. Started at the end of the Age of Oil






13. Central retriever system that uses mirrors to collect heat






14. Organic material that can be used as fuels






15. 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






16. Energy from heat contained in underground rocks






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






18. Department of Energy






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






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






21. Stores hydrogen above or below ground - very expensive






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






23. Initial cost plus lifetime opperating cost






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






25. Mixture of steam and water droplets






26. Use bowls basically to store sunlight






27. Ocean Thermal Energy Conversion






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






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






30. Ocean Thermal Energy Conversion






31. Use of passive solar energy and solar cells






32. Mixture of steam and water droplets






33. Department of Energy
