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. Distributed reciever system with sunlight collected and focused on pipes






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






3. Central retriever system that uses mirrors to collect heat






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






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






6. Mixture of steam and water droplets






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






8. Use bowls basically to store sunlight






9. Department of Energy






10. Stores hydrogen above or below ground - very expensive






11. Low dam is built across a stream






12. Initial cost plus lifetime opperating cost






13. Energy from heat contained in underground rocks






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






15. Started at the end of the Age of Oil






16. Use of passive solar energy and solar cells






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






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

32. Steam with no water droplets






33. Mixture of steam and water droplets






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






35. Low dam is built across a stream






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






37. Pumps using surplus electricity from a powerplant pump water from one lake to another






38. Initial cost plus lifetime opperating cost






39. Department of Energy






40. 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
