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






3. 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






4. Most used energy source in the united states






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






6. Burning to get heat and electricity






7. Hardness - volatility


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






9. Photovoltaic (PV) devices or Solar Energy Plant






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






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






12. Radiant energy from the sun heats Earth and atmosphere






13. Lowest rank of coal






14. Burning wood






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






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






17. Barrage dam






18. Solid to liquid biomass with chemistry and heat






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






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






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






22. Mechanical energy (wind) to electricity






23. Just burning biomass






24. Replenish themselves or are continuously present






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






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






27. Produces electricity and heat






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






29. Air heated more from ground near equator






30. Compact biomass with high temperatures - increading the VED






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






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






33. Burning 'rubbish.'






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






35. Energy resource that can replenish itself






36. Heat and Electricity






37. Pockets of hot water or steam underground






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






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






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






41. Bacteria ferment BM with sugars






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. Time - heat - pressure






45. Air cools more quickly over land than water
