In what timeframe?

Solar panels last 20-25 years. Nuclear power plants last for 50+ years and use fraction of the space that solar. It is hard to believe that the TCO is lower. Usually people just looking at the price in the short term and comparing that. Batteries are a whole different can of worms. Super toxic and you need a high volume of those because the energy density is much lower.

In the timeframe of the duration of the installation. (Total cost for the whole project + total costs for fuels & maintainance) / (kW generated * lifetime of the project)

[datadeft]

Again, comparing apples to oranges.

If 50 years we need to build a single nuclear plant while you have to build twice the solar capacity I doubt that solar come out cheaper.

[jacobp100]

It literally does come out cheaper. It’s referred to as the LCOE - you can look at the data yourself

Space isn't really an issue. There's many places that are no good for building but are great for solar, like mountainsides.

Besides, if the Netherlands can have solar then Italy can too. It's much less densely populated.

And nuclear lasts 50+ years with constant maintenance, which is really expensive.

> no good for building but are great for solar, like mountainsides.

And what's the cost of building on a mountainside, and how much is maintenance?

> Besides, if the Netherlands can have solar then Italy can too

How much solar are they building in comparison to other sources?

> And nuclear lasts 50+ years with constant maintenance, which is really expensive.

Unlike solar panels built on mountainsides which are not suitable for other types of buildings?

Maintaining solar panels will be always way, way, waaay cheaper, than maintaining a nuclear reactor and disposing safely the waste.

Batteries would need to be cheaper, that is all that is needed for italy. In the south, they have sun all year around.

Citization needed. Actually we do not know and we are figuring this out.

Few examples:

Batteries would need to be safer, less toxic and less prone to be mined by children in Africa, also orders of magnitude more energy dense.

See how you decided to completely ignore my question. But I like that on top of that, batteries are not cheap either

[lukan]

See how I am still free to ignore any question you asked and answer just what I want?

Which would be: there is not really a need for stationary batteries to be expensive.

It's a very common tactic by renewables maximalists, and I'm very familiar with it

The lifetime difference is a standard talking point that sounds good if you don't understand economics but doesn't make a significant difference. It's the latest attempt to avoid having to acknowledge the completely bizarre costs of new nuclear built power through bad math.

CSIRO with GenCost included it in this year's report.

Because capital loses so much value over 80 years ("60 years + construction time) the only people who refer to the potential lifespan are people who don't understand economics. In this, we of course forget that the average nuclear power plant was in operation for 26 years before it closed.

Table 2.1:

https://www.csiro.au/-/media/Energy/GenCost/GenCost2024-25Co...

The difference a completely absurd lifespan makes is a 10% cost reduction. When each plant requires tens of billions in subsidies a 10% cost reduction is still... tens of billions in subsidies.

[notTooFarGone]

and in 0-10 years solar make infinitely more power than a nuclear plant.

[datadeft]

Absolutely. And we can finally infent FTL and fly back in time to stop nuclear to begin with. ¯\_(ツ)_/¯
