Again, I’m not talking of costs, that’s a whole different discussion. Only pointing out the environmental impact. Although I very much believe in a few decades we’re going to find out the hard way how much more expensive it is not to have spent the money now, and we’re going to be wishing we did.
We certainly need to spend the money now on #renewables to get #ZeroCarbon and mitigate #climate breakdown.
I assume you are talking about #embodied energy and found this.
But I would say embodied energy of renewables or #nuclear is almost irrelevant as it is a one off. It’s an investment so will reap a massive reward in CO2 reduction year on year.
However, cost is a real problem for nuclear. And in terms of scaling up fast, #wind & #solar seem best.

That’s exactly what I’m talking about, yes.
Investing only in what’s fast is the kind of short sighted thinking that has put us in this situation in the first place. We need diversity on the grid if we’re serious about decarbonising. But also, Japan and South Korea can build nuclear plants in 4-5 years, why can’t we?
Because there are a number of problems with #nuclear
It’s so expensive it requires state support to even get the financing off the ground. And a wealthy state at that.
Safety issues mean the risk has to be underwritten by a government as no insurer will touch it
Disposal costs destroy the economic viability so this has to be underwritten by the state
They consume huge amounts of water
So, even China is backing off from nuclear
