Donald Trump may have pulled out of the Paris climate agreement, but apparently, some individuals in his administration see things a little differently when it comes to renewable energy and CO2 emissions.

Gary Cohn, top economic adviser to the Trump administration and director of the National Economic Council, has recently said that he thinks wind, solar and natural gas are part of America’s energy future. Cohn recently expressed his skepticism that the coal industry could be revived in any meaningful sense, and said that natural gas, wind, and solar power should be the focus of America’s energy future.

“Coal doesn’t even make that much sense anymore as a feedstock. Natural gas, [of] which we have become an abundant producer [and] which we’re going to become a major exporter of, is such a cleaner fuel,” said Cohn. “If you think about how much solar and wind we’ve created in the United States, we can become a manufacturing powerhouse and still be environmentally friendly.”

However, despite Cohn’s comments, the Trump administration is apparently in an internal debate over the country’s energy policy, with Cohn’s comments receiving pushback from Steve Bannon and his supporters. Bannon and his supporters have apparently referred to Cohn as “Carbon Tax Cohn” and “Globalist Gary.” Cohn appears to have his work cut out for him if he hopes to convince the Trump administration of the value of renewable energy sources.
