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






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






3. Stores hydrogen above or below ground - very expensive






4. Initial cost plus lifetime opperating cost






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






6. Use of passive solar energy and solar cells






7. Energy from heat contained in underground rocks






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






9. 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






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






11. Ocean Thermal Energy Conversion






12. Low dam is built across a stream






13. Initial cost plus lifetime opperating cost






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






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






16. 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






17. Low dam is built across a stream






18. Central retriever system that uses mirrors to collect heat






19. Steam with no water droplets






20. Homes with walls made of bales covered with plaster or adobe






21. Energy from heat contained in underground rocks






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






23. Ocean Thermal Energy Conversion






24. Started at the end of the Age of Oil






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






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






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






28. Mixture of steam and water droplets






29. Started at the end of the Age of Oil
