Uh are we reading the same article. Nuclear is clearly the safest in Table 2. The Lancet article is less specific with actual deaths from wind and solar but we have those stats from other sources. The Lancet article handily repeats all the usual problems with renewables.You should have another look at that Lancet article you mention. Here you go - https://www.thelancet.com/journals/lancet/article/PIIS0140-6736(07)61253-7/fulltext.
Note the fact that solar and wind are in last place in terms of effects on human heath in both the short and long term, described as "small". Articles I've read and quoted earlier in the thread indicate managing environmental impact to fauna are trivial compared to nuclear facilities for both types.
As for your other points, disposing of wind turbines is a snap, as the towers and drivetrain are metal. Only the blades are problematic, but they last at least 25 years anyway, and can last many more with enhanced inspection regimes. I don't know as much about solar panels but IIRC there are few disposal or handling concerns. We have several customers of our technolgy coming up with automated inspection systems for the inside and outside of turbine blades for this very reason.
Nuclear waste is of course manageable, but I disagree about scalability. For nuclear to make much of a dent in world carbon emissions, the developing world would need to adopt it en mass, and the geopolitical risks of that are absolutely huge. Wind and renewables face no such scalability problems and can be deployed immediately. And lastly, gas and hydro are excellent standby options, however rarely they are required.
I disagree abour scalability with wind and solar. The physical constraints mean that they cannot be scaled up enough to meet the needs of developing countries. Which is why we are seeing coal, gas and nuclear (India, China) fill in the gaps.
The question marks around renewable transmission are not trivial either. A small number of high voltage transmission lines is much cheaper to build and operate than a large number of small transmission lines. This is part of the reason why energy prices in countries with a large portion of renewables is climbing despite the marginal cost of renewables being close to 0. Note: energy prices reflect average cost.
