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. Radiant energy from the sun heats Earth and atmosphere






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






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






4. 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






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






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






7. Barrage dam






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






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






10. Most used energy source in the united states






11. Energy resource that can replenish itself






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






13. Compact biomass with high temperatures - increading the VED






14. Burning wood






15. Bacteria ferment BM with sugars






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






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






18. Burning 'rubbish.'






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






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






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






22. Most used renewable resource in the United States






23. Mechanical energy (wind) to electricity






24. Burning to get heat and electricity






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






26. Solid to liquid biomass with chemistry and heat






27. Pockets of hot water or steam underground






28. Produces electricity and heat






29. Time - heat - pressure






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






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






32. Air cools more quickly over land than water






33. Lowest rank of coal






34. Just burning biomass






35. Hardness - volatility

36. Heat and Electricity






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






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






39. Photovoltaic (PV) devices or Solar Energy Plant






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






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






42. Replenish themselves or are continuously present






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






44. Air heated more from ground near equator






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