Looking at one location doesn't really prove them wrong. And the UK is hardly running all electric now is it? Plus a lot of homes use non-electric to heat, so you need the infrastructure to run ALL the cars and heat/cool ALL the homes and businesses, and it needs to cover varying degrees of population density over large areas. Plus you need renewable for everything else, i.e. stuff from the store.

"Even if one were to electrify all of transport, industry, heating and so on, so much renewable generation and balancing/storage equipment would be needed to power it that astronomical new requirements for steel, concrete, copper, glass, carbon fibre, neodymium, shipping and haulage etc etc would appear. All these things are made using mammoth amounts of energy: far from achieving massive energy savings, which most plans for a renewables future rely on implicitly, we would wind up needing far more energy, which would mean even more vast renewables farms - and even more materials and energy to make and maintain them and so on. The scale of the building would be like nothing ever attempted by the human race.

In reality, well before any such stage was reached, energy would become horrifyingly expensive - "

It seems like it would be a lot cheaper to simply have the places affected move to slightly higher ground to me.
