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. Energy from heat contained in underground rocks






2. Stores hydrogen above or below ground - very expensive






3. Energy from heat contained in underground rocks






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






5. Corporate Average Fuel Economy






6. Ocean Thermal Energy Conversion






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






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






9. Department of Energy






10. Steam with no water droplets






11. Corporate Average Fuel Economy






12. Department of Energy






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






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






15. 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






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






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






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






19. 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






20. Low dam is built across a stream






21. Central retriever system that uses mirrors to collect heat






22. Mixture of steam and water droplets






23. Use bowls basically to store sunlight






24. Steam with no water droplets






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






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






27. Use of passive solar energy and solar cells






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






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






30. Started at the end of the Age of Oil






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






32. Ocean Thermal Energy Conversion
