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






2. Department of Energy






3. Ocean Thermal Energy Conversion






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






5. Use of passive solar energy and solar cells






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






7. Organic material that can be used as fuels






8. Corporate Average Fuel Economy






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






10. Organic material that can be used as fuels






11. Started at the end of the Age of Oil






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






13. Mixture of steam and water droplets






14. Corporate Average Fuel Economy






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






16. Initial cost plus lifetime opperating cost






17. Energy from heat contained in underground rocks






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






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






20. Use of passive solar energy and solar cells






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






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






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






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






25. 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






26. Use bowls basically to store sunlight






27. Department of Energy






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






29. 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






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






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






32. Stores hydrogen above or below ground - very expensive






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






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






35. Ocean Thermal Energy Conversion






36. Low dam is built across a stream






37. Steam with no water droplets






38. Use bowls basically to store sunlight






39. Started at the end of the Age of Oil






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






41. Central retriever system that uses mirrors to collect heat






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






43. Mixture of steam and water droplets
