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






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






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






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






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






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






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






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






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






10. Steam with no water droplets






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






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






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






14. Use bowls basically to store sunlight






15. Stores hydrogen above or below ground - very expensive






16. Steam with no water droplets






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






18. Low dam is built across a stream






19. Energy from heat contained in underground rocks






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






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






22. Low dam is built across a stream






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






24. Initial cost plus lifetime opperating cost






25. Started at the end of the Age of Oil






26. Use of passive solar energy and solar cells






27. Use bowls basically to store sunlight






28. Department of Energy






29. Department of Energy






30. Corporate Average Fuel Economy






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






32. Organic material that can be used as fuels






33. 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






34. Ocean Thermal Energy Conversion






35. Mixture of steam and water droplets






36. Central retriever system that uses mirrors to collect heat






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






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