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






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






3. Use bowls basically to store sunlight






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






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. Low dam is built across a stream






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






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






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






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






11. Use bowls basically to store sunlight






12. Corporate Average Fuel Economy






13. Initial cost plus lifetime opperating cost






14. 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






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






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






17. Low dam is built across a stream






18. Department of Energy






19. Central retriever system that uses mirrors to collect heat






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






21. Organic material that can be used as fuels






22. Steam with no water droplets






23. Central retriever system that uses mirrors to collect heat






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