The AI boom is pitting local residents against corporate giants seeking to power their energy-hungry networks – but one Welsh city is fighting back

Dale Johnston opens the gate to his neat suburban garden on the western fringes of Newport in South Wales. There’s a trampoline and a slide on the lawn for his grandchildren, and chairs for him and his wife. He should be enjoying the light draining from the perfect autumnal sky – but almost his entire view is blotted out by a vast expanse of prefabricated panels.

The 23 metre-high grey hulk looming over him and his neighbours is a hyperscale datacentre. It is heralded by the area’s Labour politicians as a job creator, yet all Johnston can think about is what he has lost: “Before, the sun used to come around here and it was lovely.” The way residents have been treated is “disgusting”.
