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. Central retriever system that uses mirrors to collect heat






2. Steam with no water droplets






3. Organic material that can be used as fuels






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






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






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






7. Low dam is built across a stream






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






9. Low dam is built across a stream






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






11. Stores hydrogen above or below ground - very expensive






12. Use bowls basically to store sunlight

20. Started at the end of the Age of Oil






21. Corporate Average Fuel Economy






22. Started at the end of the Age of Oil






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






24. 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






25. Use bowls basically to store sunlight






26. Central retriever system that uses mirrors to collect heat
