The problem with renewable energies is that they're just not reliable enough.

@iwein @lispi314 @emily_s @gardengeek @schratze True. The rapid growth of renewables is our only hope and is happening, with predictions being exceeded every year. It's not Game Over yet, and there's some chance that current conflicts will further accelerate the transition.
If cement industry was a country it would rank 7th for emissions (Economist some yrs ago). EU's CBAM should help w some of the diversion to China and others will need to follow. US insanity will (must) be unsustained.
@samueljohnson @iwein @emily_s @gardengeek @schratze Now if only we could have a solution to cement/concrete's CO2 it'd be great.
edit: Apparently injecting CO2 into concrete as it sets mineralizes it on the spot which is interesting to know, I suppose. -

If we'd invest all the budgets going into war right now into research instead, it wouldn't take more than a few decades before we can produce something like graphene at scale.
Not super realistic under capitalism and fascism, but certainly possible from a more scientific perspective.
Oh well

Is that viable? I legitimately don’t know how modern buildings (that aren’t ridiculous skyscrapers justified primarily by absurd car-centric land-use regulations and ego) are built.
For instance, why is brick less common now? Is it worse?
For steel the initial refinement is magnitudes worse than any future recycling/reuse though. So that might be something to incentivize somehow.

I could see adversary states funding research in an attempt to destabilize some country’s industries that happen to be focused on production of one thing or another.

@lispi314 small homes are best built from organic materials. That's already being done and works well.

@iwein That's a bit vague though. The environmental impact of SFH is pretty awful regardless of the materials as a consequence of the sprawl & its effects on infrastructural requirements.
At the same time, it's not like prefab-style apartments aren't feasible with wood and unlike in the past we have these fancy sprinkler things now. -

Where is your wind and solar power supposed to come from now that the strait of Hormuz is blocked?
@schratze Thanks, I laughed hard.

most steel is recycled these days. not a lot of new steel has been made in the past 80 years.

@schratze the problem with energy, whether renewable or fossil, is not so much its production (i.e., generation, storage, transmission, and distribution) but rather our insatiable consumption of it.
this is not so much a problem of energy per-se but rather that society has mutated to have ever more consumption as the only source of satisfaction, the only raison-d-etre.
The problem is that it simply doesnt work. People don't get happy with insatiable consumption. The highest consuming society (the US) is tearing itself apart rather than enjoy the privilege
In the end the path to sustainability must solve this deeper and more difficult problem
