Friends of the Earth is no longer fundamentally opposed to nuclear power and neither is the Green party of England and Wales. They still oppose nuclear power, but now because of its cost and how long it takes to build, but they’re quite happy to keep existing power stations running. They no longer see them as inherently dangerous and needing to be shut down at the first available opportunity.
You don’t often see badges or bumper stickers with slogans like that. The antinuclear ones are all over the place. If future historians look back on this era perhaps they’ll conclude that a major factor influencing our failure to decarbonise rapidly enough was that the environmental movement put its resources into campaigning against the wrong power source. Though other future historians would say nah, don’t be silly. The greens were never that influential.
