Many of the comments here are asking the wrong question - its not a matter of whether miners should be able to buy power plants and licences; so much as why it was cost effective for a disused coal plant to be acquired instead of a purchase of 25% of a specific wind farm's output, for example - the latter would drive renewable expansion, and the energy industry is already all over the fact this is the most cost effective way forward.
Bitcoin is making coal economical whereas a year ago coal was on the way out because it was not cheaper than wind and solar. So we are headed backwards. Very frightening
