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






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






4. Initial cost plus lifetime opperating cost






5. Ocean Thermal Energy Conversion






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






7. Use of passive solar energy and solar cells






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






9. Corporate Average Fuel Economy






10. Energy from heat contained in underground rocks






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






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






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






14. Steam with no water droplets






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






16. Started at the end of the Age of Oil






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






18. Organic material that can be used as fuels






19. Low dam is built across a stream






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






21. Stores hydrogen above or below ground - very expensive






22. Central retriever system that uses mirrors to collect heat






23. Steam with no water droplets






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






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






26. Mixture of steam and water droplets






27. Use of passive solar energy and solar cells






28. 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






29. Low dam is built across a stream






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






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






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






33. Energy from heat contained in underground rocks






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