After President Donald Trump's decision to exit the Paris Climate Agreement on June 1st, 2017, an agreement of 195 nations (including the US), developed in order to avoid a 2 degree Celsius rise in global temperatures, he pronounced that he was elected by "the people of Pittsburgh, not Paris", a statement centered on his campaign promise to revive the dying coal industry.  However, a closer look is needed to determine what is actually leading to the decline of coal energy production and how the United States' energy landscape has changed over the past decade. When examining the data from the November 2017 Month Energy Review, since the mid 2000s, coal consumption has declined steady being surpassed by increasing natural gas consumption. 
For the specific month of August 2017, using the data provided in Fig. 1 in Quadrillion BTUs, Petroleum consumption totaled 3.148 , followed by natural gas at 2.153 and coal at 1.371.  This equates to 38.1%, 26.0%, and 16.6%,respectively, of the total 8.265 consumption for August 2017. This growth in production is attributed technological advancements in horizontal drilling and high volume hydraulic fracking.  These improvements resulted in a surplus of shale gas in 2009 resulting in a decrease in natural gas prices.  Competitive pricing, cost efficiency, and reduced emissions, have resulted in natural gas municipals small-duty fleets such as buses and garbage trucks. 
During August 2017, U.S. Energy consumption slightly outpaced energy production. However, the significant downward trend of U.S. Energy Net Imports since its peak in 2005 coupled with an increase in U.S. Exports of Petroleum and Natural Gas shows a positive movement towards energy independence and possible increased exportation driven by cost-efficiency.
