"There?s plenty of good ol? UK coal under your feet. As for peat, peat is not a renewable resource."
Of course there is "plenty of good ol? UK coal under your feet" and I think it was costing something like GBP250 per ton, NUM permitting to get hold of it. The price of coal mined and shipped from abroad at around the time you are talking about was about GBP16 to 8 per ton. Now as a well educated scientist perhaps you can tell us which industrial base is more commercially competitive on the world market. One that is paying GBP 250 per ton of coal to generate electrical power needed by industry, or one that is paying GBP 8 per ton?
As for that coal, like peat, it is not a renewable resource either.
