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. Organic material that can be used as fuels






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






3. Energy from heat contained in underground rocks






4. Corporate Average Fuel Economy






5. Ocean Thermal Energy Conversion






6. Steam with no water droplets






7. Initial cost plus lifetime opperating cost






8. Initial cost plus lifetime opperating cost






9. Mixture of steam and water droplets






10. Use of passive solar energy and solar cells






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






12. Ocean Thermal Energy Conversion






13. Stores hydrogen above or below ground - very expensive






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






15. Use bowls basically to store sunlight






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






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






18. 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






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






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






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






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






23. Department of Energy






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






25. Corporate Average Fuel Economy






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






27. Use of passive solar energy and solar cells






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






29. 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






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






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






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






33. Started at the end of the Age of Oil






34. Organic material that can be used as fuels






35. Mixture of steam and water droplets






36. Steam with no water droplets






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






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






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






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