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






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






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






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






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






6. 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






7. Time - heat - pressure






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






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






10. Bacteria ferment BM with sugars






11. Burning 'rubbish.'






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






13. Most used energy source in the united states






14. Energy resource that can replenish itself






15. Barrage dam






16. Photovoltaic (PV) devices or Solar Energy Plant






17. Air heated more from ground near equator






18. Burning wood






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






20. Pockets of hot water or steam underground






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






22. Mechanical energy (wind) to electricity






23. Most used renewable resource in the United States






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






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






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






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






28. Solid to liquid biomass with chemistry and heat






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






30. Compact biomass with high temperatures - increading the VED






31. Replenish themselves or are continuously present






32. Heat and Electricity






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






34. Air cools more quickly over land than water






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






36. Hardness - volatility

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






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






39. Just burning biomass






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






41. Produces electricity and heat






42. Radiant energy from the sun heats Earth and atmosphere






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






44. Burning to get heat and electricity






45. Lowest rank of coal
