Gas to Electric Turbines
Natural gas, because of its clean burning nature, has become a very popular fuel for the generation of electricity. In the 1970's and 80's, the choices for most electric utility generators were large coal or nuclear powered plants; but, due to economic, environmental, and technological changes, natural gas has become the fuel of choice for new power plants. In fact, in 2009, 23,475 MW (megawatts) of new generation capacity are planned in the U.S. Of this, over 50%, or 12,334 MW, will be natural gas fired additions. The graph below shows how, according to the Energy Information Administration (EIA), natural gas fired electricity generation is expected to increase dramatically over the next 20 years, as all of the new capacity that is currently being constructed comes online.

There are many reasons for this increased reliance on natural gas to generate our electricity. While coal is the cheapest fossil fuel for generating electricity, it is also the dirtiest, releasing the highest levels of pollutants into the air. The electric generation industry, in fact, has traditionally been one of the most polluting industries in the United States . Regulations surrounding the emissions of power plants have forced these electric generators to come up with new methods of generating power, while lessening environmental damage. New technology has allowed natural gas to play an increasingly important role in the clean generation of electricity.
