Energy Issues

  1. 1. Global Warming<br />WednesdayDecember 15th<br />
  2. 2. Climate Change: Historically<br />Not a “new” concept<br />Scientists have determined that the earths temperatures have had a wide range for the last million years<br />Last Ice Age roughly 100 000 years ago ( Canada was covered in glaciers)<br />Range of + or – 0.5 degrees Celsius (although small) can have a large impact <br />Climate change has had drastic effects at the poles (grasshopper effect) http://topics.nytimes.com/top/news/science/topics/globalwarming/index.html<br />
  3. 3. Climate Change: The Greenhouse Effect <br />Necessary for life on earth<br />Has existed for as long as the earth has had an atmosphere<br />Without the greenhouse effect the earths temperature would be 33 degrees Celsius colder (more like -19 C)<br />Greenhouse Gases (GHGs)- metaphor refers to the earths atmospheres ability/ reliance to hold onto heat<br />
  4. 4. The Grasshopper Effect<br />A global issue in which POPs move from warmer to colder regions. <br />The pollutants evaporate, travel through the atmosphere (on air currents), and then condense in a new location.<br />Tend to stay in colder regions because there is less evaporation in those areas. <br />
  5. 5. The Grasshopper Effect<br />Less Evaporation <br />Colder <br />Polar Regions<br />Temperate Regions<br />More Evaporation <br />Hotter<br />Equatorial Regions<br />
  6. 6. The Ozone Layer<br />Forms the stratosphere and protects us from the suns UV Radiation<br />Human activities are upsetting the balance of this gas<br />In 1983 it was confirmed that there was a whole in ozone (over Antarctica)<br />In 1998 the hole measured 26 million Km’s (roughly the size of Australia)<br />How is it being destroyed?<br />Chloroflouorocarbons (CFCs)- once they rise into the stratosphere, they become exposed to UV radiation and release chlorine atoms<br />A single chlorine atom can destroy thousands of molecules of ozone<br />
  7. 7. The Ozone Layer<br />How is it being destroyed?<br />Chloroflouorocarbons (CFCs)- once they rise into the stratosphere, they become exposed to UV radiation and release chlorine atoms<br />A single chlorine atom can destroy thousands of molecules of ozone<br />
  8. 8. Copy to your notes:<br />Acidic Deposition Diagram pg 288<br />Effects of Acidic Deposition Chart pg 290<br />Effects of UV Radiation pg 294<br />What is the Montreal Protocol?<br />
  9. 9. Energy Issues:<br />Energy Use Worldwide:<br />Industrialized Countries<br />Non renewable- <br />Oil- <br />Coal- <br />Natural Gas- <br />Nuclear Power- <br />Renewable- <br />Hydroelectric, solar and geothermal- <br />Biomass- <br />
  10. 10. Energy Issues:<br />Developing Countries<br />Non renewable-<br />Oil -<br />Coal- <br />Natural Gas- <br />Nuclear- <br />Renewable- <br />Hydroelectric, solar and geothermal- <br />Biomass- <br />
  11. 11. Energy Issues:<br />Conventional Energy Uses <br />Fuels- materials that are burned to produce heat or power<br />Traditional:<br />Wood<br />Field crops<br />Fecal material<br />Peat (decaying plant matter found in bogs)<br />
  12. 12. Energy Issues:<br />Conventional Energy Uses Continued <br />Fossil Fuels:<br />Coal<br />Petroleum and Natural Gas<br />Migration (crude oil and natural gas migrated sideways and upward from the place of their formation, permeate into sedentary rocks <br />
  13. 13. Energy Issues:<br />Alternative Energy Uses:<br />Solar Energy<br />Passive solar energy<br />Active solar energy<br />Solar cookers<br />Photovoltaic cells <br />Advantages and Disadvantages<br />Hydroelectric Power (water)<br />Energy from Oceans<br />Advantages and Disadvantages<br />
  14. 14. Energy Issues:<br />Alternative Energy Uses Continued <br />Geothermal Energy<br />Advantages and Disadvantages<br />Wind Energy<br />Advantages and Disadvantages<br />Nuclear Energy<br />Advantages and Disadvantages<br />Biomass<br />Biogas<br />Ethanol and Methanol<br />Advantages and Disadvantages<br />
  15. 15. Energy Issues:<br />Alternative Energy Uses Continued <br />Hydricity (hydrogen)<br />Means of storing electricity for future use <br />Hydrogen can be stored and liquefied<br />Helps for us to reduce our dependence on fossil fuels and more like western Europe/ Japan<br />Advantages<br />Flexibility<br />Reduce oil dependency<br />Reduction of environmental damage = water<br />Disadvantages<br />Replacing current energy infrastructure<br />Will take evolutionary change <br />Cornucopian view for a sustainable future <br />
