Depends how much area you want to repurpose (note that it includes roads, power lines, and regular tree trimming near those power lines in addition to the turbines themselves), but I'd estimate that with current and projected Finnish population density, this would actually be a realistic option, yes. Now that I think of it, I've never anyone speak of the impact on wildlife, nor seen a wind turbine in a forest (only e…
Finland has a vast and long coast that could be used to build on or offshore farms. There are also wave hydro systems and Finland has many rivers etc that could be used. Really a choice to go nuclear. Not a necessity.

Re: Finland starts much-delayed nuclear plant, brings respite to power market
#352What's surprising is the length of time of this project. It was started in 2000, and just completed. That's 23 years of development. These nuclear projects appear to take a significant amount of time. By comparison, this wind turbine project near my parents was approved in 2016 and completed in 2018, providing 78 megawatts of power. Yes that's significantly less than the 1.6 gigawatts of this Finnish power plant. But…
Funnily enough, the 2nd and 3rd EPRs in China both opened before this one, taking "only" 9 years from start to production. They're also the world's largest reactors now.

To produce 1 gigawatt of power you need 1000 square kilometers of wind turbines or 300 sq km of solar elements or 3 sq km of nuclear power plants. How much land do you have in your country that you are ready to deforestate in order to build renewables?
Predictability.
Renewables depend on weather. They only work when the wind blows or the sun shines. Are you ready to be able to heat your house only when the weather forecast is good?

And heat-polluted waste waters? People keep pretending there are no externalities.
What prevents heated waste water from being used for…heat? Surely Finland uses central heating plants that pump hot water throughout the city (or maybe that’s just a Chinese/Russian thing?). What makes waste heat water less suited to heating, higher entropy?
The plants are also located away from cities, so utilizing the waste heat for district heating is uneconomical.

While 23 years to build the thing are already bad, it now needs to operate continuously for at least some 30 years selling electricity at a price that is even today not competitive with renewables to make financial sense. Essentially, building a nuclear power plant in 2022 means you are betting we won't have workable storage for renewables by 2052.
Add that in and the equation looks substantially different.

On top of that, some solar installations are actually compatible with some foods, here's one article on that: https://www.dw.com/en/farmers-reap-double-benefits-with-sola...
Point being, land use doesn't need to be single purpose in your example.
In terms of the weather, this is why it important to have balanced installations and associated battery storage.

Yes, if we throw capital at the problem and fast track regulatory approval, I don't see why that's not possible. Do you think it's not?
You don't want to "fast track" nuclear security and this is not something you can iterate by building unsafe plants first. Even as it is, people don't want a nuclear plant in their backyard and it's a long process to find and secure a suitable location. You'd need huge amounts of capital with big risks and little profits foreseen. The track record from the latest western projects is horrible so I don't see how it wou…
Ok, so nationalize it. Problem solved.

Without including storage and overbuilding of solar and wind to provide the same capacity factor as nuclear it is not a fair comparison, so it doesn’t point out how uneconomical this nuclear project is. The attractiveness of 1.6 GW of nuclear power is that it is carbon free, statistically the safest, it is firm energy that can be depended upon 24x7x365, and fuel costs are so trivial nobody even brings them up. All of…
You cannot depend on nuclear 24x7x365 as we’ve been able to see in France and Germany the last few years. Hot temperatures in summer cause the temperature of the rivers to increase so much that the water cannot be used for cooling and so these plants have to be shut down. That’s only going to become worse.

The worst case of nuclear, it is worse than the worst case of solar/wind. So even if it were rational for humanity, it might not be rational for a country.
I'm having trouble picturing how it is safer than solar though.
