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. Use of passive solar energy and solar cells






2. Corporate Average Fuel Economy






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






4. Low dam is built across a stream






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. Started at the end of the Age of Oil






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






8. Department of Energy






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






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






11. Organic material that can be used as fuels






12. Ocean Thermal Energy Conversion






13. Low dam is built across a stream






14. Mixture of steam and water droplets






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






16. Mixture of steam and water droplets






17. Started at the end of the Age of Oil






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






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






20. Corporate Average Fuel Economy






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






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






23. Use bowls basically to store sunlight






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






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






26. Initial cost plus lifetime opperating cost






27. Stores hydrogen above or below ground - very expensive






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






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






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






31. Steam with no water droplets






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






33. Energy from heat contained in underground rocks






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






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






36. Initial cost plus lifetime opperating cost






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