The military coup in Niger has raised concerns about uranium mining in the country by the French group Orano, and the consequences for France's energy independence.
Also, hopefully longer term we move towards more rooftop solar rather than farm scale, though of course the amount of land used by solar is insignificant. Short term, farm scale is easy to install; long term, rooftop could be a requirement of construction.
Just as important, once we reach 95%+ renewable electricity, the ecological cost of building new stuff, whether recycled or not, drops dramatically.
Do we want to move towards more nuclear in the long run? Maybe so. On the other hand, the cost of renewables will continue to come down, and it’s reasonable to expect the same is true of storage.
@Ardubal@MattMastodon@BrianSmith950@Pampa@AlexisFR@Wirrvogel@Sodis Also I expect demand to drop somewhat in the long term. Unfortunately the more serious degrowth measures will take decades, and the peak demand from heating and EVs means we will need a lot more electricity in 2040 than we have today.
@Ardubal@MattMastodon@BrianSmith950@Pampa@AlexisFR@Wirrvogel@Sodis There is also the near-absolute worst case scenario where outdoor agriculture becomes untenable due to wildly inconsistent post-climate weather and the “land sharing vs land sparing” debate is forced down the land sparing route, i.e. if most food can only be grown in heated greenhouses, we’ll need vast amounts of energy. In that scenario we may well need more nuclear. But if it’s that bad that fast I have my doubts that civilisation can survive the transition; that sort of agriculture is very capital intensive as well as energy intensive, although it is higher yield and makes space for rewilding, and potentially could be our only option if things get really bad.
PS I am not endorsing climate controlled indoor agriculture here. I don’t have a clear view on the land sharing vs land sparing thing. I know which side most “degrowth” people would take though.
We have the luxury of debate over #renewables vs #nuclear. If we could meet 100% of our energy need through nuclear that would at least be a problem solved.
We have many other problems - eg food production
Whether is it fertiliser production, replacing dirty tractors and oil based transport & shipping. Or coping with increased #climate volatility.
Sorry, but the term »degrowth« is a red flag for me.
Sure, we are getting more efficient over time. That’s why even Germany’s emissions fell over the last two decades.
But cutting power that is actually needed means poverty, and that will immediately end support for long-term thinking as well as severely limit our technical options.
There are too many people for romantic visions of rural self-sufficiency.
‘#degrowth is a red flag for me’ - seems an odd thing to say.
It is not a new idea that humanity is meeting it’s natural limits and will have to cut it’s cloth & that the #climatecrisis challenge should be shouldered equally.
In some ways degrowth has already happened in #energy where we are using less energy than was predicted through demand side measures.
@Ardubal @MattMastodon @BrianSmith950 @Pampa @AlexisFR @Wirrvogel @Sodis Fortunately we will have time to work on that. There is plenty of existing renewable plant coming to the end of its service life for us to work on recycling.

I think you do not realize how much of our population only exists because of Haber and Bosch.

This is a very important observation.
We have the luxury of debate over #renewables vs #nuclear. If we could meet 100% of our energy need through nuclear that would at least be a problem solved.

Whether is it fertiliser production, replacing dirty tractors and oil based transport & shipping. Or coping with increased #climate volatility.
We need solutions here fast.

Degrowth sounds interesting to me.
