Britain used to rely almost exclusively on coal for its electricity generation, mining it in Wales and the north and central part of England, then bringing it, usually by train, to power stations where it could be burned to heat up water that would generate electricity. Then the water was cooled down in cooling towers that can still be seen in many parts of the country.

My friend Phil Coppell, a Liverpool Blue Badge Tourist Guide, tells me that he took Ray Davies a member of the English rock band The Kinks on a Beatles tour some years ago. He queued up and paid for his ticket like everyone else and, during the tour, mentioned that he had originally set his song Waterloo Sunset in Liverpool but the line ‘Mersey Sunset’ did not scan and he moved it to London. He had always had a soft spot for Liverpool and said that whenever The Kinks played at the Cavern or other venues they always had a great reception.
