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. Lowest rank of coal






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






3. Heat and Electricity






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






5. Mechanical energy (wind) to electricity






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






7. 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






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






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






10. Hardness - volatility


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






12. Most used energy source in the united states






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






14. Produces electricity and heat






15. Pockets of hot water or steam underground






16. Barrage dam






17. Most used renewable resource in the United States






18. Burning to get heat and electricity






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






20. Time - heat - pressure






21. Bacteria ferment BM with sugars






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






23. Air heated more from ground near equator






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






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






26. Solid to liquid biomass with chemistry and heat






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






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






29. Burning wood






30. Energy resource that can replenish itself






31. Burning 'rubbish.'






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






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






34. Compact biomass with high temperatures - increading the VED






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






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






37. Radiant energy from the sun heats Earth and atmosphere






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






39. Air cools more quickly over land than water






40. Replenish themselves or are continuously present






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






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






43. Just burning biomass






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






45. Photovoltaic (PV) devices or Solar Energy Plant
