Because, having switched off the coal fired power stations at Millibrain's behest, most of our generated electricity is now sourced by burning gas. AND the majority of our electricity on average is from gas as we don't have any other means of supporting the base load given the lack of spending on nuclear (and hydro I suppose.)
You really couldn't make it up?
I think that the facts don’t support your comments. Gas is no longer the predominant annual source of electrical power generation, and its usage will only reduce further as new renewables come on line, HPC comes on line and when more progress is made on Sizewell C and Small Modular Reactors. In conjunction various forms of energy storage will support short term peak demands and there are the two way inter connectors between Britain and Europe too.

Plus gas generates much less pollution and carbon dioxide than coal fired stations, so I really find it difficult to support the nostalgic wish for the continuation of coal fired units.
Is natural gas really better than coal? How big are the greenhouse gas emissions when different fuels are burned? Here is a comparison of these fuels.

We are in the middle of a big transformation of how we derive our energy. It’s naive to expect no problems but I for one look forwards to having a house like our first one where there’s no gas heating, no water pipes to leak, and have fully controllable warmth throughout the house 24/7 from discrete panel radiators. But at my age that’s probably a dream too far, apart from entering a care home.
