As in so much else, Trump is on the wrong side of history here. His reversal of climate change initiatives will be short-lived. Within a few years there will be change in government and his environmental polices will be reversed. Meanwhile the US risks losing ground to the ongoing global investment in clean technologies and energy storage. US energy companies must surely realize this. If I were on the board of such a company I would be very reluctant to spend on reinvesting in the coal industry when it will take at least two years to put that money to work and when I know, almost to a certainty, that the policies that make the investment viable will be undone long before we get our money back,
