Canada

Firstly, the standard lifespan for modern solar panels is typically 25 to 30 years, while nearly all grid scale batteries are rated for 5000 to 8000 0-100% cycles, which is 13 to 20 years of daily cycling. If you are not completely discharging the batteries every day that lifetime can be far longer.

Secondly, it’s worth remembering that said rated lifespan is not when the pannel or battery stops working, but rather the point at which it hits 80% of the capacity it had when installed. This means that when that happens if you just do nothing for another decade or two, you are still getting well more than half of a brand new power plant’s worth of output for free, as this output is often not calculated in the cost of the plant. This also means you only need to replace panels on the same timeline as nuclear plants need far more expensive complete refurbishments.

Thirdly, yes, solar outputs less than it does in some parts of the world, which means you need proportionally more space and funding to build it. Still far less than the cost of a nuclear plant of the same output, and as for land use, I was unaware that Canada was such a small dense country, completely devoid of parking lots much less vast grassland parries.

Finally, you realize that nuclear plants have far higher operational costs than wind and solar, with the Pickering plant for instance requiring over three thousand staff to keep operating, while most solar fields don’t even have a single full time employee?

Ultimately however, the largest demonstration that nuclear will not clean up Canada’s energy is that in the quarter century that Canada had known without doubt that it must replace its oil and gas plants, it has not tried to do so with nuclear despite building nuclear reactors only getting more and more expensive with each passing year. As such, of the government has so thoroughly demonstrated it is unwilling to replace oil and gas with a more expensive option, maybe we should focus our efforts on getting them replaced with less expensive options instead.
