Coal no longer king in TVA region as more gas-fired plants used to generate electricity

In this mention

TVA's shift away from coal-fired generation accelerates as natural gas becomes cheaper and more abundant through hydraulic fracturing. Coal now produces only one-third of TVA's power, down from 52 percent in fiscal 2011, while gas consumption jumped 70 percent in 2012. The Southern Alliance for Clean Energy welcomes the transition for its environmental benefits but cautions that gas price volatility makes it unsuitable as a long-term energy solution.
