There's still some politicss to overcome, but if the cheapest source of energy is low carbon then the problem is mostly solved in the big picture. As long as we don't hit too many tipping points we should be okay.
While low carbon electricity might be the cheapest source of energy on spot markets, that's a really tiny part of the picture. We still need to figure out large scale storage and electrify everything, those aren't solved problems.
But let's assume we solve them. Do we have enough metallic resources on Earth that we can extract cheaply? Do we have enough cheap fossil fuels left to actually do that?
New sources of energy have made the world consume more of the old ones, not less. Same thing with technological innovation and gains in energy efficiency.
