Meanwhile in Italy, the whole renewables discussion is gaslighted by "we should actually consider nuclear" and "wind turbines ruin the panorama".

I'm not against nuclear per se, but it's like this part of italians don't realize that:

1. if you decide to make a power plant today, it won't be online before the 2050s, in the best case scenario. It's very difficult to bring nuclear plants online, especially in the west. Even the countries with the capital and know-how (US and France) see more projects cancelled than brought online. I think US has put online a single nuclear plant in 20 years, France not a single one.

2. Nuclear needs tons of water, we have less and less of it as it rains less and global warming doesn't accumulate enough snow in the alps (which generally melts in the summer), our rivers are literally dry stone most of the year.

3. Renewables can be attached to the grid (or close to where they are needed) in the span of few months and with very little know-how required.

4. Money isn't limitless, building a 20B+ nuclear plant (realistically 50 knowing these projects + Italy) means this budget won't be available for the next decade on projects that could bring benefits immediately.

I'm sure that Italy and Germany, which are manufacturing heavy countries that need lots of energy cannot rely renewables alone, of course nuclear should be considered, but hell, in my region (around Rome), 95% of our energy comes from imported natural gas, I'm sure we could invest some more in that.

I’m anti nuclear on cost reasons but that’s excessively pessimistic. Nuclear can use seawater for cooling, and being colder offsets the cost premium of using salt water.

Your 2050’s comment assumes a level of dysfunction that’s presumably exaggerated. Averaging 10 years puts you at 2036 and is itself somewhat pessimistic.

The cost of canceled nuclear projects is generally quite low compared to lifetime subsidies of nuclear. Nuclear may be an inefficient use of government resources, but it’s also offset a staggering amount of emissions and the subsidies tend to end back up in the local economy recuperating some of the expense. IMO, there’s probably dumber things your government is doing that are worth fighting instead.

Australia fortunately has a political neutral research organisation (CSIRO) whose job is to estimate the net cost benefit for various government programs.

Detail and detail on cost benefit analysis https://www.csiro.au/en/news/All/Articles/2024/December/Nucl...

Needless to say not at all cost effective to go nuclear at this point. There's no reason that wouldn't hold similarly in other nations since the scale of the difference in costs are so huge too.
