It didn't, at least not in the way you think. The headlines of the past few days show the aftermath of the last decades: industry contracts that were made in the last century and the political heritage of a generation of politicians who are no longer in power.

Coal is being phased out and that's not changing. It cannot change substantially anyway; there is only so much coal in the gound. Recent political decisions moved to keep most of it there. For technological, political, economical and industry related reasons this won't be a fast process unfortunately.

One of the roadblocks of our transition to a sustainable energy supply is how much money (and in our capitalisic society, therefore, power) the industry itself holds. Coal lobbies will work hard for you not to think about them too much. Nuclear lobbies will work hard for you to blame those pesky environmentalists. A game of distraction and blame shifting. This thread is a good example of how well it's working.

Our resources are limited. This is true for good old planet earth as well as our societies. We only have so much money, time, and workforce to manage this transition. And as much as I'd love to wake up tomorrow to a world with PVC on every roof, a windmill on every field, and decentralised storage in every town center, this is just not realistic overnight. We'll have to live with the fact of our limited resources and divert as much as possible of them towards such a future. (And btw, putting billions of dollars in money, time, and workforce towards a reactor that will start working in 10-30 years is not the way to do this, as much as the nuclear lobby would like you to think that.)
