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. Just burning biomass






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






4. Burning wood






5. Most used renewable resource in the United States






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






7. Produces electricity and heat






8. Time - heat - pressure






9. Photovoltaic (PV) devices or Solar Energy Plant






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






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






12. Burning 'rubbish.'






13. Mechanical energy (wind) to electricity






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






15. Most used energy source in the united states






16. Burning to get heat and electricity






17. Pockets of hot water or steam underground






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






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






20. Air heated more from ground near equator






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






22. Barrage dam






23. Air cools more quickly over land than water






24. Compact biomass with high temperatures - increading the VED






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






26. Hardness - volatility


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






28. Replenish themselves or are continuously present






29. Heat and Electricity






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






31. Bacteria ferment BM with sugars






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






33. Radiant energy from the sun heats Earth and atmosphere






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






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






36. 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






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






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






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






40. Solid to liquid biomass with chemistry and heat






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






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






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






44. Energy resource that can replenish itself






45. Lowest rank of coal
