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






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






3. Mixture of steam and water droplets






4. Energy from heat contained in underground rocks






5. Mixture of steam and water droplets






6. Organic material that can be used as fuels






7. Low dam is built across a stream






8. Started at the end of the Age of Oil






9. Use of passive solar energy and solar cells






10. Department of Energy






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






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






13. Steam with no water droplets






14. 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






15. Corporate Average Fuel Economy






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

18. Corporate Average Fuel Economy






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






20. Use bowls basically to store sunlight






21. Started at the end of the Age of Oil






22. Stores hydrogen above or below ground - very expensive






23. Central retriever system that uses mirrors to collect heat






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

26. Use of passive solar energy and solar cells






27. Initial cost plus lifetime opperating cost






28. Organic material that can be used as fuels






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






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






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






32. Initial cost plus lifetime opperating cost






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






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