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. Finite supply being used faster than they can be replenished






2. Time - heat - pressure






3. Photovoltaic (PV) devices or Solar Energy Plant






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






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






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






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






8. Burning 'rubbish.'






9. Most used renewable resource in the United States






10. Heat and Electricity






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






12. Replenish themselves or are continuously present






13. Mechanical energy (wind) to electricity






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






15. Solid to liquid biomass with chemistry and heat






16. 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






17. Produces electricity and heat






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






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






20. Burning wood






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






22. Air heated more from ground near equator






23. Just burning biomass






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






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






26. Energy resource that can replenish itself






27. Barrage dam






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






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






30. Most used energy source in the united states






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






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






33. Hardness - volatility


34. Compact biomass with high temperatures - increading the VED






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






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






37. Radiant energy from the sun heats Earth and atmosphere






38. Pockets of hot water or steam underground






39. Bacteria ferment BM with sugars






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






41. Burning to get heat and electricity






42. Air cools more quickly over land than water






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






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






45. Lowest rank of coal
