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. Energy from heat contained in underground rocks






2. Steam with no water droplets






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






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






5. 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






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






7. Low dam is built across a stream






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






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






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






11. Energy from heat contained in underground rocks






12. Initial cost plus lifetime opperating cost






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






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






15. Low dam is built across a stream






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






17. Organic material that can be used as fuels






18. Corporate Average Fuel Economy






19. Use of passive solar energy and solar cells






20. Central retriever system that uses mirrors to collect heat






21. Ocean Thermal Energy Conversion






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






23. Ocean Thermal Energy Conversion






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






25. Stores hydrogen above or below ground - very expensive






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






27. Organic material that can be used as fuels






28. Use of passive solar energy and solar cells






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






30. Stores hydrogen above or below ground - very expensive






31. Use bowls basically to store sunlight






32. Department of Energy






33. 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






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






35. Mixture of steam and water droplets






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






37. Started at the end of the Age of Oil






38. Use bowls basically to store sunlight






39. Corporate Average Fuel Economy
