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






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






3. Heat and Electricity






4. Hardness - volatility


5. Air cools more quickly over land than water






6. Burning wood






7. Solid to liquid biomass with chemistry and heat






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






9. Burning 'rubbish.'






10. Most used renewable resource in the United States






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






12. Mechanical energy (wind) to electricity






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






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






15. Air heated more from ground near equator






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






17. Bacteria ferment BM with sugars






18. Produces electricity and heat






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






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






21. Replenish themselves or are continuously present






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






23. Barrage dam






24. Just burning biomass






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






26. Time - heat - pressure






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






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






29. Most used energy source in the united states






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






31. Pockets of hot water or steam underground






32. Photovoltaic (PV) devices or Solar Energy Plant






33. Burning to get heat and electricity






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






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






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






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






38. Energy resource that can replenish itself






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






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






42. Lowest rank of coal






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






44. Radiant energy from the sun heats Earth and atmosphere






45. Compact biomass with high temperatures - increading the VED
