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. Started at the end of the Age of Oil






2. Mixture of steam and water droplets






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






4. Initial cost plus lifetime opperating cost






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






6. Started at the end of the Age of Oil






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






8. Energy from heat contained in underground rocks






9. Use of passive solar energy and solar cells






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






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






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






13. Steam with no water droplets
