When Nuclear power had promising developments with the Integral Fast Reactor, Big Oil undermined it in a similar way.
First they reframed the mission of Greepeace, who was always drawing scrutiny to Oil and Coal projects into one that was scrutinising Nuclear power, when it was actually more concerned about nuclear weapons.
Then when all the nuclear supporters were distracted and point their vitriol at Greenpeace, Greenpeace were no longer able to draw attention to Big Oil's activities and keep them under scrutiny.
Meanwhile, Big Oil got to lobby congress for changes to energy policy unhindered, successfully defunding the IFR Project and the most promising breakthrough to nuclear power ever made. Something Greenpeace would more than likely have supported were they given a chance to examine the technology and see it fitted in with their mission for nuclear disarmament.
Solar advocates beware, the playbook is virtually the same. Draw scrutiny away from Big Oil, create infighting amongst supporters. The only thing remaining is to look out for what lobby activities are occurring that frame new energy policy to benefit Big Oil and Coal over Solar Power.
