I want to share a very quick thought about President Trump's decision to pull out of the Paris Agreement. First, it's a non-issue, a moot point. The climate change accord was non-binding, so we could enter and exit at will. Second, President Trump is correct -- the deal doesn't really benefit the U.S., while other nations, namely China and India, can almost do as they please. Third, let's not pretend that this decision was shocking because it wasn't. This was about as telegraphed as a move as you can get.
Having said all that, the benefits that the Trump administration foresees by pulling out is also a non-issue. Coal, Trump's baby, is declining. The combustion process, no matter how you cut it, will always be inefficient compared to electrical energy. Innovation is about moving forward, not backward. So his overtures to coal miners are just that -- coal mining is only relevant on a quadrennial cycle.
And in a few generations, it may not be relevant at all!
