Renewable Energy

Subject : science
Instructions:
  • Answer 45 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. Natural gas that is super cooled to gas phase so it can be transported easier/safer






2. Mechanical energy (wind) to electricity






3. What country leads the world in wind energy generating?






4. Same as pyrolysis BUT - more heat and less gas






5. Burning to get heat and electricity






6. Heat is recovered as steam or hot water to: 1. Create electricity 2. Heat buildings






7. Photovoltaic (PV) devices or Solar Energy Plant






8. Most used renewable resource in the United States






9. Bacteria ferment BM with sugars






10. Least expensive alternate energy - Sustainable - Renewable - No carbon emission - Once tower is up - almost no cost to maintain






11. Energy resource that can replenish itself






12. Environmental Impact - High startup cost - Low efficiency in some cases






13. Where the most Geothermal Energy is produced in all of the United States






14. Heat and Electricity






15. Release less than 1% of CO2 - Hydrogen Sulfide pollution - 97% less acid rain pollutants - Sources of geothermal are often National Treasures






16. Pockets of hot water or steam underground






17. Just burning biomass






18. Air heated more from ground near equator






19. Acidic precursors from coal mines get into surrounding water sources due to rain flushing them out






20. Air is heated from ground - warm air flows upward - cold air replaces it






21. Volumetric energy density---- increased by pelletisation






22. Radiant energy from the sun heats Earth and atmosphere






23. Hardness - volatility


24. Pumping water into an oil well to increase pressure and improve recovery






25. Shifting of ground as a result of drilling/mining under it






26. Finite supply being used faster than they can be replenished






27. Time - heat - pressure






28. Most used energy source in the united states






29. The difference between low and high tide. the height difference.






30. Naturally occurring substance that can potentially be extracted using modern technology






31. Solid to liquid biomass with chemistry and heat






32. Bacteria breaks biomass down without oxygen with product mixed gas. LFG's






33. Replenish themselves or are continuously present






34. Produces electricity and heat






35. Air cools more quickly over land than water






36. Barrage dam






37. Known deposits which can be extracted from profitably using modern technology under certain economic conditions






38. Secondary Pollution (Toxic materials and alcohols - Blocking the sun for some animals - No direct pollution though!) - Bird death ray - Startup cost






39. High start-up cost - Unreliable - Energy companies see it as a supplemental power - Strong winds usually not near population - Energy grids are not set up for wind






40. Burning 'rubbish.'






41. Energy that can be obtained from movement of water due to gravitational pull of sun - moon - and Earth's rotation.






42. Compact biomass with high temperatures - increading the VED






43. Burning wood






44. Lowest rank of coal






45. It's reliable and consistent - It gives off very little pollution - Lessen the burden of fossil fuels and nuclear energy!
