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






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






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






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






5. Radiant energy from the sun heats Earth and atmosphere






6. Solid to liquid biomass with chemistry and heat






7. Produces electricity and heat






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






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






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






11. Time - heat - pressure






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






13. Burning 'rubbish.'






14. Burning to get heat and electricity






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






16. Energy resource that can replenish itself






17. Air heated more from ground near equator






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






19. Most used energy source in the united states






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






21. 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






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






23. Pockets of hot water or steam underground






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






25. Heat and Electricity






26. Lowest rank of coal






27. Compact biomass with high temperatures - increading the VED






28. Mechanical energy (wind) to electricity






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






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






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






32. Burning wood






33. Hardness - volatility

34. Bacteria ferment BM with sugars






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






36. Just burning biomass






37. Replenish themselves or are continuously present






38. Air cools more quickly over land than water






39. Barrage dam






40. Photovoltaic (PV) devices or Solar Energy Plant






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






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






43. Most used renewable resource in the United States






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






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