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. Just burning biomass






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






3. Time - heat - pressure






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






5. Air cools more quickly over land than water






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






7. Most used energy source in the united states






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






9. Solid to liquid biomass with chemistry and heat






10. Bacteria ferment BM with sugars






11. Mechanical energy (wind) to electricity






12. Compact biomass with high temperatures - increading the VED






13. Photovoltaic (PV) devices or Solar Energy Plant






14. Barrage dam






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






16. 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






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






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






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






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






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






22. Burning wood






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






24. Replenish themselves or are continuously present






25. Pockets of hot water or steam underground






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






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






28. Air heated more from ground near equator






29. Lowest rank of coal






30. Hardness - volatility


31. Burning 'rubbish.'






32. Energy resource that can replenish itself






33. Heat and Electricity






34. Burning to get heat and electricity






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






36. Radiant energy from the sun heats Earth and atmosphere






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






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






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






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






41. Most used renewable resource in the United States






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






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






44. Produces electricity and heat






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