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. Energy from heat contained in underground rocks






2. Energy from heat contained in underground rocks






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






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

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






9. Steam with no water droplets






10. Department of Energy






11. Stores hydrogen above or below ground - very expensive






12. Use of passive solar energy and solar cells






13. Corporate Average Fuel Economy






14. Use bowls basically to store sunlight






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

17. Department of Energy






18. Low dam is built across a stream






19. Ocean Thermal Energy Conversion






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






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






22. Ocean Thermal Energy Conversion






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

25. Corporate Average Fuel Economy






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






27. Mixture of steam and water droplets






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






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






30. Central retriever system that uses mirrors to collect heat






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






32. Central retriever system that uses mirrors to collect heat






33. Started at the end of the Age of Oil






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






35. Use of passive solar energy and solar cells






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






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






38. 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






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






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






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






42. Organic material that can be used as fuels
