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. Corporate Average Fuel Economy






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






4. Steam with no water droplets






5. Ocean Thermal Energy Conversion






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






7. Use bowls basically to store sunlight






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






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






10. Stores hydrogen above or below ground - very expensive






11. 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






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






13. Initial cost plus lifetime opperating cost






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






15. Organic material that can be used as fuels






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






17. Mixture of steam and water droplets






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






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






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






21. Central retriever system that uses mirrors to collect heat






22. Started at the end of the Age of Oil






23. Ocean Thermal Energy Conversion






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






25. Energy from heat contained in underground rocks






26. Corporate Average Fuel Economy






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






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






29. Use of passive solar energy and solar cells






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






31. Use bowls basically to store sunlight






32. Use of passive solar energy and solar cells






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






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






35. Organic material that can be used as fuels






36. Department of Energy






37. Central retriever system that uses mirrors to collect heat

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






48. Started at the end of the Age of Oil






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






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