  1. Hydraulic Fracturing Beau Greiner

  2. Natural Gas • The term “natural gas” generally refers to methane gas • It is advertised as a “clean” fossil fuel • The use of natural gas has been expanding in the United States since the 1950s • Many of the natural gas reserves in the U.S. are locked in deposits of Shale, a sedimentary rock

  3. “Fracking”: The Process • Oil companies have recently expanded the use of Hydraulic Fracturing to remove the natural gas from Shale deposits • The process involves pumping water, chemicals, and sand down a well, and into fissures in the rock • Involves the use of explosive charges • Millions of gallons of water per well

  4. Pros • Efficient extraction of natural gas • Extends life of wells, decreasing cost of extraction • Natural gas emits less carbon dioxide than oil or coal

  5. Cons • Chemicals from the frackingfluid can leak into environment, and contaminate ground water • Millions of gallons of water are used to develop each well • Fossil fuels are not sustainable, and lead to pollution of the environment • http://fracfocus.org/water-protection/drilling-usage

  6. The Technology in the Future • Demand for Natural Gas is expanding, and so is the use of Hydraulic Fracturing • The damage that it does to the environment is difficult to assess, and varies from well to well • Ultimately, more sustainable energy sources are necessary for continued consumption
