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 heated more from ground near equator






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






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






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






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






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






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






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






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






10. Radiant energy from the sun heats Earth and atmosphere






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






12. Hardness - volatility

13. Most used energy source in the united states






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






15. Replenish themselves or are continuously present






16. Barrage dam






17. Mechanical energy (wind) to electricity






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






19. Bacteria ferment BM with sugars






20. Burning wood






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






22. Photovoltaic (PV) devices or Solar Energy Plant






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






24. Air cools more quickly over land than water






25. Heat and Electricity






26. Energy resource that can replenish itself






27. 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






28. Most used renewable resource in the United States






29. Burning 'rubbish.'






30. Burning to get heat and electricity






31. Compact biomass with high temperatures - increading the VED






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






33. Just burning biomass






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






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






36. Produces electricity and heat






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






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






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






40. Time - heat - pressure






41. Lowest rank of coal






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






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






44. Pockets of hot water or steam underground






45. Solid to liquid biomass with chemistry and heat
