> it's been outmoded by superior technology I assume you mean natural gas, since renewables are still a small portion of the overall energy mix. Bear in mind that fracked gas wells decline much faster than conventional ones, and the only reason gas is so cheap is due to fracked wells. It's anybody's guess how long this "superior technology" will last. Let's also not ignore the fact that coal use has effectively been exported to China as the UK/US increasingly rely on manufacturing abroad. We still share a single atmosphere, and global coal consumption is up 6.2% from 2010, regardless of how much the UK/US have reduced their specific share: https://www.worldometers.info/coal/ https://www.worldometers.info/coal/
