  6. Pollution and its Effects on our Environment http://www.iea.org/ieaenergy/

  7. Carbon Dioxide Emissions The largest human source of carbon dioxide emissions comes from the combustion of fossil fuels. Three major types of fossil fuels Coal Natural gas Oil

  8. CO2 Emissions on a Global Scale Apart from being created by human activities, carbon dioxide is also released into the atmosphere by natural processes. The Earth's oceans, soil, plants, animals and volcanoes are all natural sources of carbon dioxide emissions. At the beginning of the 18th century, human sources of carbon dioxide upset this natural balance with the dawn of the Industrial Revolution. http://www.epa.gov/climatechange/ghgemissions/global.html

  9. Our Transportation Sector, the Second Largest source of CO2 Emissions A large percentage of our CO2emissions come from our road vehicles Smog hanging over highways gives off an eerie yellow haze http://www.takepart.com/article/2013/06/04/los-angeles-air-pollution-decline

  10. Another significant polluting source The number of ships navigating between U.S. and China is contributing to many of our environmental problems. 14 percent of all transport emissions are caused by marine shipping. Air pollution from cruise ships is generated by diesel engines that burn highsulfur content fuel. http://www.rtcc.org/2012/12/17/eu-targets-air-pollution-with-tightened-shipping-rules/

  12. Types of Water Pollution Wastewater from commercial andindustrial waste (intentionally or through spills) Urban and agricultural runoff Surfacerunoff flowing to public waterways http://www.ustudy.in/node/1890

  13. Soil contamination The most significantsoil contaminants are: Hydrocarbons Herbicides Pesticides Insecticides http://www.sciencedaily.com/articles/s/soil_contamination.htm

  14. Soil Contamination in Agriculture http://www.epa.gov/superfund/students/wastsite/soilspil.htm

  15. Environmental Impact of Nuclear Power uranium processing nuclear power generation Routine health risks and greenhouse gas emissions from nuclear fission power are small relative to those associated with coal, oil and gas. However, there is a "catastrophic risk" potential when nuclear containment fails, which can result in releasing large amounts of fission products into the environment. geological disposal uranium mining

  16. Waste and Garbage http://www.cleanair.org/Waste/wasteFacts.html

  18. Power Sustainability by: Riley Fukuji http://dyh9a7dlvr8qp.cloudfront.net/going-green/wp-content/uploads/2008/10/print-city-sustainability-energy-environment.jpg

  19. Not Sustainable • Oil • Natural Gas • Coal Any other thing that can not be naturally replenished in duration of your life http://www.vintagemodelairplane.com/images/Snippets/Smoke05.jpg

  20. Sustainable Energy • Solar • Wind • Hydroelectric • Landfill gas • Nuclear http://science.nationalgeographic.com/science/photos/sun-gallery/

  21. Nuclear Pro: Energy is abundant Cons: Fukushima Nuclear Waste http://upload.wikimedia.org/wikipedia/commons/4/4e/Nuclear_Power_Plant_Cattenom.jpg

  22. Landfill Gas Pros: Use the methane from waste Cons: Combustion of methane Emitting greenhouse gases Video:http://www.youtube.com/watch?v=w1RKMMpRRHY30sec-3min http://graphics8.nytimes.com/images/2006/05/08/us/08landfill.xlarge1.jpg

  23. Wind Cons: Not accurately predictable Scenery Pros: Cost: Free No dangerous materials involved http://reneweconomy.com.au/wp-content/uploads/2012/11/wind-turbines17.jpg

  24. Hydroelectric Pros: Efficiency is high 16% of energy produced in the world Cons: Wildlife is destroyed http://ak9.picdn.net/shutterstock/videos/833590/preview/stock-footage-hydro-electric-dam-in-the-mountains.jpg http://rosyfinch.com/DeadFish.jpg

  25. Energy Usage Average US family uses 940 kWh per month http://www.bubblews.com/assets/images/news/1199833634_1362975598.jpg Solar Efficiency: 20% Recycle: 80% recyclable material Lifetime: 20 years Cost of fuel: FREE

  26. Math: Average area of solar panel: 1.6sq meters Solar Panel Efficiency: 20% Calculations: (power from sun per day)(days per month) South West (6kWh)(30day)=(180kWh per month per sq meter)(.2)=36 kWh (940 kWh a month)/(36 kWh a month)= 26 sq meters needed 17 panels Other areas: (4kWh)(30day)=(120kWh per month per sq meter)(.2)=24 kWh (940 kWh a month)/(24 kWh a month)= 39 sq meters needed 25 panels Average United State plot of land: 185 sq meters
