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






2. 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






3. Air cools more quickly over land than water






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






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






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






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






8. Burning 'rubbish.'






9. Air heated more from ground near equator






10. Burning wood






11. Compact biomass with high temperatures - increading the VED






12. Energy resource that can replenish itself






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






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






15. Most used renewable resource in the United States






16. Mechanical energy (wind) to electricity






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






18. Most used energy source in the united states






19. Burning to get heat and electricity






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






21. Pockets of hot water or steam underground






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






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






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






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






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






27. Replenish themselves or are continuously present






28. Produces electricity and heat






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






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






31. Hardness - volatility


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






33. Barrage dam






34. Time - heat - pressure






35. Just burning biomass






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






37. Bacteria ferment BM with sugars






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






39. Heat and Electricity






40. Lowest rank of coal






41. Photovoltaic (PV) devices or Solar Energy Plant






42. Radiant energy from the sun heats Earth and atmosphere






43. Solid to liquid biomass with chemistry and heat






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






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