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






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






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






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






5. Burning 'rubbish.'






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






7. Pockets of hot water or steam underground






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






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






10. 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






11. Solid to liquid biomass with chemistry and heat






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






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






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






15. Compact biomass with high temperatures - increading the VED






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






17. Energy resource that can replenish itself






18. Time - heat - pressure






19. Air heated more from ground near equator






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






21. Barrage dam






22. Mechanical energy (wind) to electricity






23. Bacteria ferment BM with sugars






24. Just burning biomass






25. Photovoltaic (PV) devices or Solar Energy Plant






26. Air cools more quickly over land than water






27. Lowest rank of coal






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






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






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






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






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






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






34. Radiant energy from the sun heats Earth and atmosphere






35. Produces electricity and heat






36. Heat and Electricity






37. Replenish themselves or are continuously present






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






39. Most used energy source in the united states






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






41. Most used renewable resource in the United States






42. Hardness - volatility


43. Burning wood






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






45. Burning to get heat and electricity
