The problem with that is that a lot of green technology is of a big investment in the beginning, but cheaper to operate type. So once you have them, it is hard for fossil fuels to compete. We also do not have low fossil fuel prices right now. Both oil and gas are rather expensive and coal can not compete with gas in most places. More so green technologies also have a lobby. So you have the fossil fuel industry in decline, which means less money for lobbying. The laws and systems to replace them are in working already. The simple truth is that passing laws is much harder then to prevent a law from being passed. Obviously the fossil fuel industry has already failed to do the later in many places.

This is one of the reasons we currently see a lot of far right groups poping up everywhere. Fossil fuel has to rewrite the laws. Centrists do not want to do anything and leftists are for the most part for more anti fossil fuel laws. So the far right is their only hope to grow the fossil fuel industry.
