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. Low dam is built across a stream






2. Started at the end of the Age of Oil






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






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






5. Steam with no water droplets






6. Use bowls basically to store sunlight






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






8. Department of Energy






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






10. Use of passive solar energy and solar cells






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






12. Stores hydrogen above or below ground - very expensive






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






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






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






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






17. Mixture of steam and water droplets






18. Energy from heat contained in underground rocks






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






20. Stores hydrogen above or below ground - very expensive






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






22. 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






23. Energy from heat contained in underground rocks






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






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






26. Organic material that can be used as fuels






27. Started at the end of the Age of Oil






28. Use of passive solar energy and solar cells






29. Organic material that can be used as fuels






30. Initial cost plus lifetime opperating cost






31. Central retriever system that uses mirrors to collect heat






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






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






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






35. Steam with no water droplets






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






37. Initial cost plus lifetime opperating cost
