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. Replenish themselves or are continuously present






2. Energy resource that can replenish itself






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






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






5. Burning to get heat and electricity






6. Lowest rank of coal






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






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






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






10. Time - heat - pressure






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






12. Radiant energy from the sun heats Earth and atmosphere






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






14. Most used energy source in the united states






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






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






17. Solid to liquid biomass with chemistry and heat






18. 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






19. Most used renewable resource in the United States






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






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






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






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






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






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






26. Mechanical energy (wind) to electricity






27. Compact biomass with high temperatures - increading the VED






28. Barrage dam






29. Just burning biomass






30. Pockets of hot water or steam underground






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






32. Hardness - volatility


33. Air heated more from ground near equator






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






35. Burning 'rubbish.'






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






37. Heat and Electricity






38. Photovoltaic (PV) devices or Solar Energy Plant






39. Air cools more quickly over land than water






40. Burning wood






41. Bacteria ferment BM with sugars






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






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






44. Produces electricity and heat






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