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






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






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






4. Barrage dam






5. Burning 'rubbish.'






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






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






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






9. Burning wood






10. Lowest rank of coal






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






12. Replenish themselves or are continuously present






13. Bacteria ferment BM with sugars






14. Solid to liquid biomass with chemistry and heat






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






16. Time - heat - pressure






17. Photovoltaic (PV) devices or Solar Energy Plant






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






19. Burning to get heat and electricity






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






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






22. Compact biomass with high temperatures - increading the VED






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






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






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






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






27. Energy resource that can replenish itself






28. Just burning biomass






29. Air heated more from ground near equator






30. Mechanical energy (wind) to electricity






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






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






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






34. Pockets of hot water or steam underground






35. Hardness - volatility

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






37. 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






38. Produces electricity and heat






39. Most used energy source in the united states






40. Heat and Electricity






41. Radiant energy from the sun heats Earth and atmosphere






42. Air cools more quickly over land than water






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






44. Most used renewable resource in the United States






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