Fossil Fuels Are nonrenewable resources How Fossil Fuels Formed
Coal Types of Coal: Lignite (lowest quality) Subbituminous coal Bituminous coal Anthracite (highest quality)
Coal Coal Reserves
Coal Two basic types of Coal Mining: 1) Subsurface (underground) 2) Surface
Coal Safety Problems Associated with Coal 1) Increased risk of cancer 2) Black lung disease
Coal Environmental Impacts of the Mining Process: Prior to 1977, most surface mines were abandoned. Leading to water pollution and acid mine drainage. Current law requires all surface mines to be reclaimed.
Coal Environmental Impacts of Burning Coal: Increases CO 2 concentration in atmosphere Lower quality coals release sulfur and nitrogen dioxides, causing acid deposition
Coal Legislation and Technologies 1. Surface Mining Control and Reclamation Act of 1977 (SMCRA) *Acid mine drainage??? 2. Clean Air Act of 1990 *Resource Recovery 3. Clean Coal Technologies: *fluidized-bed combustion
Coal Making Coal a Cleaner Fuel Using scrubbers Using fluidized-bed combustion
Oil Major Flows of Crude Oil

Oil and Natural Gas Case-in-Point: The Arctic National Wildlife Refuge
Synfuels and Other Potential Fossil Fuel Resources Synthetic fuel sources: Tar sands (oil sands) Oil shales Gas hydrates Coal liquefaction Coal gasification Problem: these all still produce CO 2
