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






2. Time - heat - pressure






3. Photovoltaic (PV) devices or Solar Energy Plant






4. Radiant energy from the sun heats Earth and atmosphere






5. Burning to get heat and electricity






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






7. Produces electricity and heat






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






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






10. Pockets of hot water or steam underground






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






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






13. Burning wood






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






15. Compact biomass with high temperatures - increading the VED






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






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






18. Solid to liquid biomass with chemistry and heat






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






20. Just burning biomass






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






22. Air cools more quickly over land than water






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






24. Heat and Electricity






25. Energy resource that can replenish itself






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






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






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






29. Most used renewable resource in the United States






30. Bacteria ferment BM with sugars






31. Air heated more from ground near equator






32. Most used energy source in the united states






33. Hardness - volatility


34. Mechanical energy (wind) to electricity






35. Burning 'rubbish.'






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






37. Barrage dam






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






39. 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






40. Lowest rank of coal






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






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






43. Replenish themselves or are continuously present






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






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