If you want to see who supports and who opposes nuclear power in government, here’s GovTrack’s list of nuclear power bills:
GovTrack.com list of bills regarding nuclear power
I can tell you that the vast majority of ‘pro-nuclear’ bills are proposed by Republicans, while the bills that would impose new regulations or costs on nuclear power come primarily from Democrats.
This is in accordance with what I’ve seen my entire life. I’ve been fighting for nuclear power since the 1980’s, and the opponents at a national level are always on the left. You do get some bipartisan NIMBYism in local issues, but all the organizsed opposition is on the left. Greenpoeace, the Sierra Club, Friends of the Earth, Dr. Helen Caldicott’s bunch, the Union of Concerned Scientists and other large anti-nuclear groups are all on the far left. The anti-nuclear movement itself got a big boost when a bunch of Hollywood lefties made “The China Syndrome” to scare people.
The anti-nuke positions of the left really hardened in the 1970’s and 1980’s when they coincided with the international ‘peace’ organizations and the nuclear freeze movement. Anything nuclear was considered to be bad. Around this time Jimmy Carter signed an executive order banning fuel reprocessing in America, which forced nuclear plants to store their waste on-site instead of sending it for reprocessing. That’s helped create the mess the U.S. has today, while other countries like Canada, Sweden, France, Germany and others managed to build and employ nuclear plants without the same problems. You can blame the anti-nuke left for that.
The Green Party in the U.S. and the various green parties around the world got their start from the movement to prevent nuclear power from growing. The socialist international, which includes AOC’s Democratic Socialists of America, is formally opposed to nuclear power. Here in Canada, the Pembina Institute is another left-wing group trying to shut down all non-renewable energy, including nuclear. They have tremendous power in Canada, and recently had big influence over Alberta’s decision to stop the planned construction of a nuclear plant to power the steam for the oil sands, and they helped successfully block pipelines out of Alberta.
The Cassini Mission, one of the most successful space missions of all time, was almost stopped due to protests and legal attacks by Friends of the Earth and other environmental groups because it had a plutonium RTG on board.
Current anti-nuclear groups who have considerable finances and influence:
Friends of the Earth (chapters in 77 countries)
Greenpeace
The Sierra Club
The Socialist International
The Pembina Institute
Various Green Parties around the world
In Europe, the anti-nuclear groups are so powerful that countries like Belgium, Germany, Spain and Switzerland are not just freezing new construction of nuclear plants, they are decommissioning the current plants they have. Italy has already decommissioned all its nuclear plants and vows to build no more. Anti-nuke demonstrations still take place constantly in Europe. Pretty much all of it driven by the environmental left.
I did a search for right-wing anti-nuclear groups, and could not find a single one.
Anyone who thinks that opposition to nuclear power comes equally from the left and right is either engaging in historical revisionism or is ignorant to the history of nuclear power.
