That’s what their marketing would like you to believe. But they’re only carbon neutral if you take into account the carbon being sequestered by the growth of plants before they’re burned. By that measure they’re just as carbon neutral as coal.

That’s not nuclear that produces CO2, that’s mining, processing, and transportation. It’s transversal to anything you build, be it nuclear, bioenergy, wind, solar, hydro, geothermal, anything. In the ideal conditions of your power being entirely carbon-free, then so is all of that.
By that measure they’re just as carbon neutral as coal.
Well no, because coal is deep deposits of carbon which have essentially left the carbon cycle. By digging it up and burning it we are adding carbon back which otherwise wasn’t already an issue. Biofuels by definition rely on the carbon currently in the carbon cycle so they do not have this issue.
Sure, but the carbon in coal was captured from the atmosphere by plants previously (that’s what I meant by “by that measure”). Let’s just leave the carbon where it is, whether coal or plants, and not burn any more of it back into the atmosphere, please.
Point is that’s just as big an “it” as the nuclear costs. Which, in a zero emissions world, is a very small “it”. I’m not arguing against renewables, I’m arguing against fossil fuels. We need to replace all of it ASAP, and realistically nuclear is the easiest, most reliable way to reach that goal. Just compare Germany and France’s emissions per capita, and then the distribution of their power source, and electricity costs.
ASAP? Take a look at planning and construction times of nuclear plants. Like Hinkley Point C in the UK for instance. Announced in 2010, generation now postponed to 2026, years behind schedule and billions over budget. And that’s on an already pre-existing nuclear site.
Cost? Estimated 100 GBP/MWh. The difference to market prices will probably be coughed up by the taxpayer.
Renewables are way faster to install, for a fraction of the cost.
They should have started sooner and with more plants. But it’s still much better for that nuclear plant be complete in 2030, than never. Delays and mismanagement aren’t unique to nuclear, and no excuse to stop from building it.
>Renewables are way faster to install, for a fraction of the cost.
So why are we still using fossil fuels then? The best time to start building alternatives is yesterday. Second best time is now.
>Biofuels are in fact carbon neutral.

Wind, solar, geothermal etc. need constant mining of fuel?
They need one-time mining of construction material to build those things, and that’s it, for the next few decades.
