Pros and Cons
• Pros: Plentiful Resource, U.S. owns 25 percent of the worlds known coal reserves. Inexpensive compared to other energy sources. Versatile, it can be turned into a liquid or gas forms which burn cleaner than the solid form.
• Cons: Pollution from coal is widespread, leads to acid rain. Can be a health hazard to those living near the plants that process it. It is also a non-renewable resource and so we have access to a finite amount of it.
