The CO2 per kWh for both nuclear and wind and solar are well within our target range. They are effectively equivalent on that metric.
What isn't equivalent is what is used to overcome intermittency. In Germany it's coal. Here in California it's methane--yes we're failing too!
As for land usage, it's pretty clear that wind power uses less than nuclear.
You're wrong about that. Significantly wrong. Crazy person wrong.
Now, it is possibly to use nuclear without a massive source of cooling water, but that generally means a lot more land use and more expense
See Palo Verde in the middle of Arizona. If it can work there it can work anywhere. Also the electricity is sells is cheap.
it does not make sense for standard power generation on the grid. The mix can include nuclear (especially still running older plants in good condition where they can be inexpensively and safely maintained), but it should not be a major component.
Again the goal is to minimize g CO2 per kWh which nuclear is suitable for and solar/wind have yet to do anywhere in the world.
That does not account for the other four and a half percent or so that comes from burning things
Cite that. Or better yet post that to electrictymaps forums so they can improve their numbers.
You're using a rolling estimate of yearly output?
Yes. The last 12 months is a good estimate at where a country is currently at today. You can't use individual days or even months due to differences in the weather. You can also look at multyear trends to see where it is going.
Can you cite the actual primary sources the data you are using here is coming from
They cite it literally on each page. They also have forums(on github I believe) where you can suggest improvements or point out mistakes.
So, you realize that's an 11.3% increase for Germany, but a 37% increase for France, right?
It's a 7 g CO2 per kWh increase for France and a 32 g CO2 per kWh increase for Germany.
the actual precision of the numbers you present is in serious doubt.
Best available data and electricity maps continually iterates and improves. The scale of the difference between France and Germany is presented in their numbers.
