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






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






3. Bacteria ferment BM with sugars






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






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






6. Mechanical energy (wind) to electricity






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






8. Time - heat - pressure






9. Burning to get heat and electricity






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






11. Compact biomass with high temperatures - increading the VED






12. Produces electricity and heat






13. Pockets of hot water or steam underground






14. Air heated more from ground near equator






15. Lowest rank of coal






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






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






18. Solid to liquid biomass with chemistry and heat






19. Photovoltaic (PV) devices or Solar Energy Plant






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






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






22. Radiant energy from the sun heats Earth and atmosphere






23. Hardness - volatility


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






25. 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






26. Most used renewable resource in the United States






27. Most used energy source in the united states






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






29. Replenish themselves or are continuously present






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






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






32. Burning 'rubbish.'






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






34. Just burning biomass






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






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






37. Barrage dam






38. Energy resource that can replenish itself






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






40. Heat and Electricity






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






42. Air cools more quickly over land than water






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






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






45. Burning wood
