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. Low dam is built across a stream






2. Corporate Average Fuel Economy






3. Steam with no water droplets






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






5. Organic material that can be used as fuels






6. Mixture of steam and water droplets






7. Low dam is built across a stream






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

10. Corporate Average Fuel Economy






11. Mixture of steam and water droplets






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






13. 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






14. Use of passive solar energy and solar cells






15. Ocean Thermal Energy Conversion

17. Energy from heat contained in underground rocks






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






19. Central retriever system that uses mirrors to collect heat






20. Organic material that can be used as fuels






21. Department of Energy






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






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






24. Use bowls basically to store sunlight






25. Started at the end of the Age of Oil






26. Central retriever system that uses mirrors to collect heat






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






28. Use bowls basically to store sunlight






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






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






31. Stores hydrogen above or below ground - very expensive






32. Initial cost plus lifetime opperating cost






33. Department of Energy

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






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






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






48. Initial cost plus lifetime opperating cost






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






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