  1. Energy from Organic Fuels F4 Problems with Fossil Fuels

  2. Problems with Fossil Fuels • There are many problems associated with the increasing use of fossil fuels. • Scientists are looking into developing fuels from otherorganic sources. • Alternative fuels can solve some, but not all, of the problems of using fossil fuels

  3. Problems with Fossil Fuels • Availability • Fossil fuels are not renewable • All the coal, oil, and natural gas that will ever be available to humans is already formed • Cannot always depend on the deposits of oil that are already known to exist • For many nations, oil deposits are not always located in the same country that needs the fuel • In 199I, the Persian Gulf War reminded many Americans of the need to reduce their dependence on imported oil

  4. Problems with Fossil Fuels • Have to keep looking deeper beneath Earth's surface and exploring farther into natural areas to find more • Coastal states are constantly addressing the question of whether or not to explore for oil offshore • Wherever exploration for fossil fuels takes place, there is a risk of environmentaldamage • Oil spills • Other forms of habitat alteration

  5. Problems with Fossil Fuels • Pollution • Air pollution • Burning fossil fuels releases carbondioxide • The amount of carbon dioxide in the atmosphere since the Industrial Revolution has increased by more than 20 percent • Many scientists think that this increase in carbon dioxide could raise the temperature of Earth through a process called the greenhouse effect

  6. Problems with Fossil Fuels • Pollution • Water and Land pollution • Leading source of water pollution • The production and transport of fossil fuels results in routine pollution of the environment • Results in occasional catastrophic accidents

  7. Problems with Fossil Fuels • Pollution • The December 2008 collapse of a coal ash pond outside a Tennessee Valley Authority power plant covered 300 acres in sludge and will cost an estimated $825 million to clean up

  8. Problems with Fossil Fuels • Pollution • Between 1990 and 2006, 51 large oil spills in the United States alone that resulted in the expenditure of between $860 million and $1.1 billion in removal costs and compensation for damages • 1989 Exxon Valdez in Alaska • 2010 BP oil spill in the Gulf of Mexico • 2013 North Dakota oil spill • In 2013 there were 291 oils spills in ND • 22,600 barrels • 42 gallons = • 949,000 gallons

  9. Problems with Fossil Fuels • Dangerous • Natural gas is extremely combustible, so obtaining it can often be hazardous • Danger created by natural gas combustion also exists when mining for other fossil fuels • Coal miners can die of suffocation by natural gas • Miners have also perished from explosions of natural gas and coal dust.
