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






2. Distributed reciever system with sunlight collected and focused on pipes






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






4. Low dam is built across a stream






5. Mixture of steam and water droplets






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. Corporate Average Fuel Economy






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






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






10. Ocean Thermal Energy Conversion






11. Department of Energy






12. Use of passive solar energy and solar cells






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






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






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






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






17. Central retriever system that uses mirrors to collect heat






18. Distributed reciever system with sunlight collected and focused on pipes






19. Department of Energy






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






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






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






23. Stores hydrogen above or below ground - very expensive






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






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






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






27. Energy from heat contained in underground rocks






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






29. Organic material that can be used as fuels






30. Ocean Thermal Energy Conversion






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






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






33. Central retriever system that uses mirrors to collect heat






34. Use bowls basically to store sunlight






35. Started at the end of the Age of Oil






36. Use of passive solar energy and solar cells






37. Started at the end of the Age of Oil
