President Donald Trump is set to announce he is lifting an Obama-era policy that curtailed the financing of coal-fired power plants overseas, as he seeks to propel American ” energy dominance” and reorients the US government away from fighting climate change. Trump also will describe a series of other government authorisations and business deals that illustrate how US oil, natural gas and coal are coveted around the world, in a speech marking the culmination of the administration-dubbed “Energy Week,” according to a White House official who asked for anonymity to discuss the announcements before they were made public.
