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. Stores hydrogen above or below ground - very expensive






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






3. 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






4. Central retriever system that uses mirrors to collect heat






5. Use of passive solar energy and solar cells






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






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






8. Low dam is built across a stream






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






10. Mixture of steam and water droplets






11. Steam with no water droplets






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






13. Use bowls basically to store sunlight






14. Energy from heat contained in underground rocks






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






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






17. Use bowls basically to store sunlight






18. Mixture of steam and water droplets






19. Organic material that can be used as fuels






20. Department of Energy






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






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






23. Ocean Thermal Energy Conversion






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






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






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






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






28. Organic material that can be used as fuels






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






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






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






32. Central retriever system that uses mirrors to collect heat






33. Low dam is built across a stream






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






35. Department of Energy






36. Corporate Average Fuel Economy






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






38. Started at the end of the Age of Oil






39. Stores hydrogen above or below ground - very expensive






40. Started at the end of the Age of Oil






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






42. Use of passive solar energy and solar cells






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






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