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






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






4. Department of Energy






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






6. Initial cost plus lifetime opperating cost






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






8. Organic material that can be used as fuels






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






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






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






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






13. Energy from heat contained in underground rocks






14. Mixture of steam and water droplets






15. Steam with no water droplets






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






17. 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






18. Use of passive solar energy and solar cells






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






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






21. Use bowls basically to store sunlight






22. Stores hydrogen above or below ground - very expensive






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






24. Initial cost plus lifetime opperating cost






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






26. Started at the end of the Age of Oil






27. 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






28. Central retriever system that uses mirrors to collect heat






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






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






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






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






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






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






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