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






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






3. Most used energy source in the united states






4. Heat and Electricity






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






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






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






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






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






10. Barrage dam






11. Just burning biomass






12. Burning wood






13. Bacteria ferment BM with sugars






14. Hardness - volatility


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






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






17. Radiant energy from the sun heats Earth and atmosphere






18. Air heated more from ground near equator






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






20. Air cools more quickly over land than water






21. Produces electricity and heat






22. Time - heat - pressure






23. Burning 'rubbish.'






24. Pockets of hot water or steam underground






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






26. Most used renewable resource in the United States






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






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






29. Lowest rank of coal






30. Mechanical energy (wind) to electricity






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






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






33. Energy resource that can replenish itself






34. Photovoltaic (PV) devices or Solar Energy Plant






35. Burning to get heat and electricity






36. Replenish themselves or are continuously present






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






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






39. Natural gas that is super cooled to gas phase so it can be transported easier/safer






40. 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






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






42. Solid to liquid biomass with chemistry and heat






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






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






45. Compact biomass with high temperatures - increading the VED
