Cost billions and have 10 year lead times?
We're reaching the point where discussing cost in regard to the energy crisis makes us look like fucking idiots.
Imagine what kids reading the history books are going to think of these discussions.
And 10 years isn't that long really. If someone said we could use no fossil fuels in energy generation in 10 years time that doesn't sound long at all.
Cost is a proxy for productivity and resources. So while it is stupid to say that the energy transition is too expensive, shouldn't we rather invest our productivity and resources into a faster and cheaper solution? Drawing focus away from renewables is dangerous as others have mentioned, because it is too late to reach our goals with nuclear.
No I don't think so. Nuclear is super effective and consistent, especially for large setups.
Using renewables while we get our nuclear up makes complete sense. And subsidising nuclear with renewables after that also makes sense.
But the technology to rely entirely on renewables isn't really there either.

Yes, it is.
This is a book by a professor of Civil and Environmental Engineering that goes into the details. We don't need nuclear. All the tech is there.
shouldn’t we rather invest our productivity and resources into a faster and cheaper solution?
We sure should. Do tell of this this faster, cheaper solution that is also adequate to meet all of our needs.
Really gives me the warm fuzzies when someone looks at changes to physical systems over time then draws a trend line into the future indefinitely without any citations or discussion of plausibility for the part they drew on.
Which part specifically do you take issue with? It's a bounded timeframe with over 60 references. We're already 4 years into their predicted trends and on track so it seems like they are into something.
All the charts on page 15. The ones where they extrapolate exponential improvement for a decade while only citing themselves. Their prediction is 15% annually for storage cost improvements in Li-ion batteries which they call 'conservative'
Our analysis conservatively assumes that battery energy storage capacity costs will continue to decline over the course of the 2020s at an average annual rate of 15% (Figure 3).
Let us check if their souce updated. $139 for 2023? That isn't a 15% decrease since 2019's $156, let alone year over year since then, which would be under $90. In spite of last year's drop that is still more than the 2021 price of $132. I don't know what 'on track' means to you but it must be something different than it means to me.
Thank you, appreciate you showing specifically what your issue is. I agree the timeline for the battery costs hasn't worked out exactly because of some anomalies over the last year or two but the trend is sharply down again. So it seems like we are on track to achieve a cost of around $90 by 2025 now rather than 2024 at least according to Goldman Sachs.
If your issue is with the exact timeline, I say that's fair enough, but being off by a year with battery costs isn't too bad I don't think. Of course as with all forecasting we'll have to see exactly how it pans out in reality but it's a pretty big risk if you want to start building a nuclear reactor now, factoring in construction time plus payback period.
Why do they do this? The battery companies would want compensation, too!
Yes. Should have started more 10years ago, but doesn't mean don't start now.
If you start building a new nuclear plant today, it’ll start generating power around the year 2045, by which time renewables with storage will have gotten even cheaper.
Bet you the public will be on the hook to pay for that white elephant because utility companies privatize profits and socialize losses.
Why do you assume it takes that long? Are you assuming US circumstances?
That's how long they actually end up taking to build.
Look up the project history of your local NPP and see how long it was from planning approval to putting power on the grid.
It says it took 60 months on average. I guess from approval, it often took 8 years, so a decade makes sense.
Which country builds a NPP in only 5 years, China?
South Korea
Except we have better options than we did 10 years ago.
I'd be all for nuclear if we rolled back the clock to 2010 or so. As it stands, solar/wind/storage/hvdc lines can do the job. The situation moved and my opinion moved.
Wdym 10 year lead times?
