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. Same as pyrolysis BUT - more heat and less gas






2. Photovoltaic (PV) devices or Solar Energy Plant






3. Hardness - volatility


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






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






6. Heat and Electricity






7. Air cools more quickly over land than water






8. Produces electricity and heat






9. Just burning biomass






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






11. Burning wood






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






13. Radiant energy from the sun heats Earth and atmosphere






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






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






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






17. Energy resource that can replenish itself






18. Barrage dam






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






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






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






22. Mechanical energy (wind) to electricity






23. 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






24. Time - heat - pressure






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






26. Lowest rank of coal






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






28. Solid to liquid biomass with chemistry and heat






29. Compact biomass with high temperatures - increading the VED






30. Burning 'rubbish.'






31. Pockets of hot water or steam underground






32. Replenish themselves or are continuously present






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






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






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






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






37. Air heated more from ground near equator






38. Most used renewable resource in the United States






39. Bacteria ferment BM with sugars






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






41. Most used energy source in the united states






42. Burning to get heat and electricity






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






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






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