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 heated more from ground near equator






2. Burning to get heat and electricity






3. Burning 'rubbish.'






4. Burning wood






5. Most used energy source in the united states






6. Pockets of hot water or steam underground






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






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






9. Heat and Electricity






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






11. Radiant energy from the sun heats Earth and atmosphere






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






13. Hardness - volatility

14. Time - heat - pressure






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






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






17. Produces electricity and heat






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






19. Photovoltaic (PV) devices or Solar Energy Plant






20. Solid to liquid biomass with chemistry and heat






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






22. Compact biomass with high temperatures - increading the VED






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






24. Energy resource that can replenish itself






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






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






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






28. Barrage dam






29. Air cools more quickly over land than water






30. Most used renewable resource in the United States






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






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






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






34. Just burning biomass






35. Lowest rank of coal






36. Mechanical energy (wind) to electricity






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






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






39. Bacteria ferment BM with sugars






40. Replenish themselves or are continuously present






41. 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






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






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






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






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