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. Distributed reciever system with sunlight collected and focused on pipes






2. Started at the end of the Age of Oil






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






4. Stores hydrogen above or below ground - very expensive






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






6. Mixture of steam and water droplets






7. Use of passive solar energy and solar cells






8. Started at the end of the Age of Oil






9. Energy from heat contained in underground rocks






10. 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






11. Low dam is built across a stream






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






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






14. Organic material that can be used as fuels






15. Corporate Average Fuel Economy






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






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






18. Use bowls basically to store sunlight






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






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






21. Energy from heat contained in underground rocks






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






23. Initial cost plus lifetime opperating cost






24. Initial cost plus lifetime opperating cost






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






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






27. Stores hydrogen above or below ground - very expensive






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






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






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






31. Use bowls basically to store sunlight
