You won’t find “fracking” in this story but it’s why the US has been able to shift from coal to natural gas with much lower greenhouse gas emissions.
According to the Environmental Protection Agency (EPA), U.S. greenhouse gas emissions dropped 2.7 percent from 2016 levels in 2017 with emissions from large power plants falling 4.5 percent. Emissions of carbon dioxide (the largest component of greenhouse gases) on a per-capita basis hit a 67-year low in 2017. U.S. carbon dioxide emissions in 2017 are the lowest since 1992 and per-capita emissions are the lowest since 1950. According to Acting EPA Administrator Andrew Wheeler, “These achievements flow largely from technological breakthroughs in the private sector, not the heavy hand of government.”
