Solar power expected to dominate electricity generation by 2050—even without more ambitious climate policies::In pursuit of the ambitious goal of reaching net-zero emissions, nations worldwide must expand their use of clean energy sources. In the case of solar energy, this change may already be upon us.

Its not directly in the article but the primary reason Solar is its a lot cheaper than electricity production from fuel, something like 1/4 - 1/10 the price depending on where in the world you are. An energy company is basically foolish to invest in oil based electricity production when Solar is so competitive and cheap and easy to maintain. Wind is a little cheaper where there is good airflow but the maintenance cost is higher especially for offshore. Both however are so much cheaper than Nuclear and especially than oil/drilling fuels that its hard to see much real investment in those older technologies.

There has been a lot of recent complaints around the UK's granting of further drilling rights in the North sea for Oil. I think the companies taking those up haven't yet come to terms with the fact there is a good chance those ventures drive their companies to bankruptcy because they wont be competitive as EVs and Solar/Wind take over due to cost savings.

I keep telling people that the economics of nuclear - especially new plants - just doesn’t work, but here and on Reddit it seems to be a very bitter pill that many are not ready to swallow.

The time of nuclear energy has come and gone. We missed it.

I’m not some anti-nuclear energy hippie. I took nuclear reactor design courses at uni. But you just can’t make money that way anymore.

Really?

Yes really.

Molten salt reactors are not significantly cheaper to build own or operate, on the contrary. I’m making an economic argument here.

If you put economics before the environment then sure, nuclear's not viable, never was.

And oil's only viable because of mass subsidies and tax exemptions.

Wait what? Surely nuclear gets less viable if you factor in the cost of cleaning up after yourself.

And oil's only viable because of mass subsidies and tax exemptions.

That, and massive externalization.

Those molten salt reactors can run on what the current reactors create as nuclear waste. They actually help with the cleanup process by breaking the radioactive waste down to a few very short lived ions that cease to be radioactive quite quickly. The other nice part about them is that you can't make weapons with them.

I'm in favor of subsidizing nuclear reactors that can reuse waste. That's a better idea than the current strategy of letting it sit around, or the potential future of burying it and hoping nobody digs it up again millennia from now.

There is little other reason to bother with nuclear anymore.

I’m familiar with the technology. It’s great.

It won’t get built because you can’t make money off it without running the risk of government changing its mind as soon as you’re done building the thing.
