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






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






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






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






5. 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






6. Mixture of steam and water droplets






7. Steam with no water droplets






8. Department of Energy






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






10. Initial cost plus lifetime opperating cost






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






12. Ocean Thermal Energy Conversion






13. Use bowls basically to store sunlight






14. Stores hydrogen above or below ground - very expensive






15. Started at the end of the Age of Oil






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






17. Stores hydrogen above or below ground - very expensive






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






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






20. Corporate Average Fuel Economy






21. Corporate Average Fuel Economy






22. Central retriever system that uses mirrors to collect heat






23. Low dam is built across a stream






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






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






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