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. Organic material that can be used as fuels






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






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






4. Central retriever system that uses mirrors to collect heat






5. Ocean Thermal Energy Conversion






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






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






8. 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






9. Mixture of steam and water droplets






10. Use of passive solar energy and solar cells






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






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






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






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






15. Organic material that can be used as fuels






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






17. Initial cost plus lifetime opperating cost






18. Stores hydrogen above or below ground - very expensive






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






20. Steam with no water droplets






21. Mixture of steam and water droplets






22. Started at the end of the Age of Oil






23. Use of passive solar energy and solar cells






24. Department of Energy






25. Energy from heat contained in underground rocks
