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






2. Energy from heat contained in underground rocks






3. Ocean Thermal Energy Conversion






4. Started at the end of the Age of Oil






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






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






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. Mixture of steam and water droplets






10. Use bowls basically to store sunlight






11. Ocean Thermal Energy Conversion






12. 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






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






14. Organic material that can be used as fuels






15. Corporate Average Fuel Economy






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






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






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






19. Central retriever system that uses mirrors to collect heat






20. Corporate Average Fuel Economy






21. Steam with no water droplets






22. 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






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






24. Stores hydrogen above or below ground - very expensive






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






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






27. Use bowls basically to store sunlight






28. Organic material that can be used as fuels






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






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






31. Department of Energy






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






33. Initial cost plus lifetime opperating cost






34. Stores hydrogen above or below ground - very expensive
