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






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






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






5. Ocean Thermal Energy Conversion






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






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






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






9. Central retriever system that uses mirrors to collect heat






10. Started at the end of the Age of Oil






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






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






13. Department of Energy






14. Corporate Average Fuel Economy






15. Department of Energy






16. Initial cost plus lifetime opperating cost






17. Use of passive solar energy and solar cells






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






19. Use of passive solar energy and solar cells






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






21. Energy from heat contained in underground rocks






22. Organic material that can be used as fuels






23. Steam with no water droplets






24. Organic material that can be used as fuels






25. Started at the end of the Age of Oil






26. Steam with no water droplets






27. Mixture of steam and water droplets






28. 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






29. Initial cost plus lifetime opperating cost






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






31. Low dam is built across a stream






32. Energy from heat contained in underground rocks






33. Central retriever system that uses mirrors to collect heat






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






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






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






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






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






39. Use bowls basically to store sunlight






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

42. Low dam is built across a stream






43. 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






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






45. Use bowls basically to store sunlight






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






47. Mixture of steam and water droplets
