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






2. Time - heat - pressure






3. Barrage dam






4. Photovoltaic (PV) devices or Solar Energy Plant






5. Energy resource that can replenish itself






6. Replenish themselves or are continuously present






7. Heat and Electricity






8. Most used energy source in the united states






9. Lowest rank of coal






10. 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






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






12. Bacteria ferment BM with sugars






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






14. Just burning biomass






15. Pockets of hot water or steam underground






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






17. Mechanical energy (wind) to electricity






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






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






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






21. Air heated more from ground near equator






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






23. Hardness - volatility


24. Produces electricity and heat






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






26. Air cools more quickly over land than water






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






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






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






30. Radiant energy from the sun heats Earth and atmosphere






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






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






33. Burning 'rubbish.'






34. Most used renewable resource in the United States






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






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






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






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






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






40. Burning to get heat and electricity






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






42. Compact biomass with high temperatures - increading the VED






43. Solid to liquid biomass with chemistry and heat






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






45. Burning wood
