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. Photovoltaic (PV) devices or Solar Energy Plant






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






3. Just burning biomass






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






5. Solid to liquid biomass with chemistry and heat






6. Burning wood






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






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






9. Compact biomass with high temperatures - increading the VED






10. Air cools more quickly over land than water






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






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






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






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






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






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






17. Most used renewable resource in the United States






18. Bacteria ferment BM with sugars






19. Burning 'rubbish.'






20. Radiant energy from the sun heats Earth and atmosphere






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






22. 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






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






24. Lowest rank of coal






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






26. Energy resource that can replenish itself






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






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






29. Pockets of hot water or steam underground






30. Heat and Electricity






31. Most used energy source in the united states






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






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






34. Time - heat - pressure






35. Mechanical energy (wind) to electricity






36. Barrage dam






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






38. Air heated more from ground near equator






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






40. Burning to get heat and electricity






41. Replenish themselves or are continuously present






42. Hardness - volatility


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






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






45. Produces electricity and heat
