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






2. Steam with no water droplets






3. Low dam is built across a stream






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






5. Ocean Thermal Energy Conversion






6. 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






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






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






9. Central retriever system that uses mirrors to collect heat






10. Started at the end of the Age of Oil






11. Mixture of steam and water droplets






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






13. Corporate Average Fuel Economy






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






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






16. Organic material that can be used as fuels






17. Low dam is built across a stream






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






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






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






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






22. Organic material that can be used as fuels






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






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






25. Initial cost plus lifetime opperating cost






26. Use bowls basically to store sunlight






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