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. What country leads the world in wind energy generating?






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






3. Radiant energy from the sun heats Earth and atmosphere






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






5. Lowest rank of coal






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






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






8. Pockets of hot water or steam underground






9. Most used renewable resource in the United States






10. Burning to get heat and electricity






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






12. Solid to liquid biomass with chemistry and heat






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






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






15. Heat and Electricity






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






17. Time - heat - pressure






18. Compact biomass with high temperatures - increading the VED






19. Replenish themselves or are continuously present






20. Energy resource that can replenish itself






21. Bacteria ferment BM with sugars






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






23. Air heated more from ground near equator






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






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






26. Produces electricity and heat






27. Photovoltaic (PV) devices or Solar Energy Plant






28. Just burning biomass






29. Most used energy source in the united states






30. Hardness - volatility


31. Mechanical energy (wind) to electricity






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






33. Air cools more quickly over land than water






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






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






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






37. Burning 'rubbish.'






38. Burning wood






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






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






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






42. 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






43. Barrage dam






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






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