Nuclear is an ideal green solution for the fossil fuel industry. Why? Well, building a power station is super hard because: it's expensive, takes years and no one wants a power station in their backyard.
I can imagine fossil fuel execs recognising that the energy grid is going green despite all of their lobbying. So the game then becomes to delay the inevitable as long as you can, so that you can extract as much money as you can from fossil fuels.
