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. Distributed reciever system with sunlight collected and focused on pipes






3. Energy from heat contained in underground rocks






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






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






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






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






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






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






10. Ocean Thermal Energy Conversion






11. Mixture of steam and water droplets






12. Central retriever system that uses mirrors to collect heat






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






14. Organic material that can be used as fuels






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






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






17. Initial cost plus lifetime opperating cost






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






19. Use bowls basically to store sunlight






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






21. Use of passive solar energy and solar cells






22. Started at the end of the Age of Oil






23. Steam with no water droplets






24. Stores hydrogen above or below ground - very expensive






25. 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
