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. Most used renewable resource in the United States






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






4. Burning wood






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






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






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






8. Solid to liquid biomass with chemistry and heat






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






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






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






12. 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






13. Pockets of hot water or steam underground






14. Compact biomass with high temperatures - increading the VED






15. Replenish themselves or are continuously present






16. Most used energy source in the united states






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






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






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






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






21. Photovoltaic (PV) devices or Solar Energy Plant






22. Lowest rank of coal






23. Radiant energy from the sun heats Earth and atmosphere






24. Bacteria ferment BM with sugars






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






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






27. Barrage dam






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






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






30. Air cools more quickly over land than water






31. Burning to get heat and electricity






32. Energy resource that can replenish itself






33. Just burning biomass






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






35. Mechanical energy (wind) to electricity






36. Time - heat - pressure






37. Hardness - volatility

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






39. Produces electricity and heat






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






41. Air heated more from ground near equator






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






43. Heat and Electricity






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






45. Burning 'rubbish.'
