It's easy to despair these days. But I want you to remember this:
The change from fossil fuels to renewable energies cannot be stopped. Renewables and battery systems are getting better and more widespread every year. And what we are seeing right now is an extinction burst of the fossil fuel industry and their political allies. They know that they will lose their entire business model very soon, so they are doing immense amount of lobbying to squeeze as much profit out of their business as they can.
But soon, they will not matter any more. Sure, they might hold on a few centers of power for a little while longer - the USA, as well as Europe (to a lesser degree). But the rest of the world is already moving on.
The collapse of human civilization is _not_ inevitable. The fight for our environment remains important - the sooner the fossil fuel lobbies are stopped, the less damage they can do. But the outcome is not in doubt - they will fall.
