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






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






3. Ocean Thermal Energy Conversion






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






5. 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






6. Use bowls basically to store sunlight






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






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






9. Energy from heat contained in underground rocks






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






11. Use of passive solar energy and solar cells






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






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






14. Stores hydrogen above or below ground - very expensive






15. Low dam is built across a stream






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






17. Department of Energy






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






19. Mixture of steam and water droplets






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






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






22. Started at the end of the Age of Oil






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






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