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






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






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






5. Hardness - volatility

6. Most used renewable resource in the United States






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






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






9. Time - heat - pressure






10. Solid to liquid biomass with chemistry and heat






11. Radiant energy from the sun heats Earth and atmosphere






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






13. Most used energy source in the united states






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






15. Burning to get heat and electricity






16. Energy resource that can replenish itself






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






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






19. Mechanical energy (wind) to electricity






20. Just burning biomass






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






22. 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






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






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






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






26. Lowest rank of coal






27. Compact biomass with high temperatures - increading the VED






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






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






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






31. Heat and Electricity






32. Produces electricity and heat






33. Burning wood






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






35. Pockets of hot water or steam underground






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






37. Air heated more from ground near equator






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






39. Photovoltaic (PV) devices or Solar Energy Plant






40. Burning 'rubbish.'






41. Air cools more quickly over land than water






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






43. Bacteria ferment BM with sugars






44. Barrage dam






45. Replenish themselves or are continuously present
