Nuclear power plants have a massive footprint. For example in Australia they're planning to setup a new nuclear waste disposal facility with a forecast budget of half a trillion US Dollars and it will be full in 70 years time - they'll have to build a new one somewhere else after that.
That nuclear waste site will be radioactive for millions of years. The land will never be able to be used for basically anything, ever.
If you covered just that nuclear waste facility with solar panels, it would provide a massive amount of power. Enough to cover the day time power needs of a small country.
Solar panels aren't a "zany" idea. In fact one of the reasons it's being explored is because it would reduce evaporation. Power generation is often almost an afterthought. The panels also don't have to be ugly - in fact there are prototypes that are invisible. They just look like ordinary glass, and don't cost much more than glass either.
Half a trillion dollars over seventy years is nothing. How large is the waste site compared to the habitable surface? A few square kilometers is nothing.
The power needs of a small country is also essentially nothing over a seventy year span.
Nuclear energy is not ideal but it beats the hell out of coal plants, and it gives us a bridge to something sustainable. Solar has its own drawbacks and no nation is going to maintain a bunch of floating panels out in the ocean.
