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. 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






2. Use bowls basically to store sunlight






3. Steam with no water droplets






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






5. Mixture of steam and water droplets






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






7. Department of Energy






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






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






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






11. Mixture of steam and water droplets






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






13. Use of passive solar energy and solar cells






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






15. 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






16. Steam with no water droplets






17. Low dam is built across a stream






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

30. Energy from heat contained in underground rocks






31. Department of Energy






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






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






34. Organic material that can be used as fuels






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






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






37. Corporate Average Fuel Economy






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






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






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