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






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






3. Use of passive solar energy and solar cells






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






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






6. Low dam is built across a stream






7. Department of Energy






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






9. Central retriever system that uses mirrors to collect heat






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






11. Low dam is built across a stream






12. Organic material that can be used as fuels






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






14. Use bowls basically to store sunlight






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






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






17. Ocean Thermal Energy Conversion






18. Steam with no water droplets






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






20. Organic material that can be used as fuels






21. 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






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






23. Central retriever system that uses mirrors to collect heat






24. Corporate Average Fuel Economy






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






26. Ocean Thermal Energy Conversion






27. Started at the end of the Age of Oil






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

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






31. Mixture of steam and water droplets






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






33. Steam with no water droplets






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






35. Energy from heat contained in underground rocks






36. Use bowls basically to store sunlight






37. Department of Energy






38. Stores hydrogen above or below ground - very expensive






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






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