"Greens caused gigatons of carbon dioxide to enter the atmosphere from the coal and gas burning that went ahead instead of #nuclear. I was part of that too, I apologize." (Stewart Brand, 2009)
@kravietz This statement is telling the tale hat nuclar power is saving C02. But you need a lot of energy (which is from coal, oil and gas) to prepare the fule rods.
You need a lot of energy too to mine coal, gas, oil as well as rare earth metals required for manufacture of solar panels and wind turbines.
This is all quantified already - overall CO2 intensity of wind farm is 15 gCO2e/kWh, most of which is infrastructure, while nuclear is 5 gCOe/kWh *including* infrastructure, fuel and waste management.
@kravietz I have to admit that I'm not an export o this topic. But the graphs you showed are not really trustworthy for me. Esp. the second one might be from Vattenfall (and thus biased) as it is title "… Vattenfall …".
Also on could admirably argu about whether the "decommissioning" really uses that less C02 - given that you actually recommision and not only burry it in e.g. Asse.
@kirschwipfel As for decommissioning - yes, you *could* argue. But when arguing let's present *data* rather than baseless whataboutism.
@kravietz "Don't trust any statistic you did not forge yourself." Without deep knowledge about which decommission scenario has been evaluated, this it hard to take as granted. And if the figures are from Vattenfall: They are biased for sure.
@kirschwipfel So you are not an exper, don't know anything about costs of decomission but you already know nuclear is *not* an option. Sorry, but this is very much a religious approach.
You basically say: solar and wind are not options. This might be true - I'm not into this topic yet. You are into this, so I'll accept it for the sake of this discussion.
But due to its adherent risks, nuclear power is not an option either.
So we end up with either killing mankind by CO2 (coal, gas, solar, wind) or radioactive contamination (nuclear). Sound like choosing between pest and cholera, don't it?
We need clean energy without CO2 *today*, because if not we will likely face extinction my mid-century.
There's a lot of stupid lobbying out there (e.g. in Poland for coal mining) but the root cause why solar/wind are not working *today* are science and engineering.
