Where is your wind and solar power supposed to come from now that the strait of Hormuz is blocked?
@schratze I write to you, heartbroken and in tears, for my dear mother.
I’m Kholoud from Ga🥺za. My 90-year-old mother is blind, immobile, and recently had a stroke. She cries from painful sores because we ran out of diapers. Pleease heeelp us with the cost of diapers and one package of her stroke medication (Eliquis) only

lots of conflicting stories going around. hard to know what to believe. according to these two sources, china has been decreasing coal use for the last four years.https://www.macrotrends.net/global-metrics/countries/chn/china/coal-usage-consumption
@fishidwardrobe @iwein @emily_s @gardengeek @schratze
My understanding is that at least part of the confusion is due to China building both new coal plans and renewables at a very high rate.
They are adding a lot of new coal plants, but the proportion of total energy produced by coal still declines when you factor in all the new solar and wind they're doing at the same time.
I am not a reliable source (although I do my best)! I think @parismarx discussed this in a recent episode of the #TechWontSaveUs podcast on the #GreenTransition

@plantarum @iwein @emily_s @gardengeek @schratze @parismarx figures i linked to are not proportionate to solar. just coal consumption.

@fishidwardrobe @iwein @emily_s @gardengeek @schratze @parismarx
From 2025. Lots of interesting details, including solar growing in proportion to coal, while coal continues to grow in absolute volume as well.
"China is on its way to becoming the world’s first “electrostate”, with a growing share of its energy coming from electricity and an economy increasingly driven by clean technologies ...
China remains the world’s biggest greenhouse gas producer and its power sector emissions reached a new high last year, driven by a rise in coal consumption... still the dominant fuel in its electricity mix, despite a surge in renewable capacity additions."

@schratze you wanted to say "they're not reliable enough in increasing the profits of shady regimes through manufactured crises"?

@schratze I'm putting a 10% tax on wind!

@schratze I hear that some companies are starting to offshore their wind turbines though.

@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.

@iwein @emily_s @gardengeek @schratze Nevertheless the share of China's energy that comes from coal is declining fast and will continue to do so
https://ourworldindata.org/grapher/share-energy-source-sub?country=~CHN
Furthermore, some of the new coal plants replace older inefficient ones and produce fewer emissions.
One would almost think the Chinese have expected trouble in t' gulf and planned accordingly.
@samueljohnson@mstdn.social @iwein@mas.to @emily_s@mastodon.me.uk @gardengeek@mstdn.social @schratze@todon.nl Those powerplants do have a limited lifespan.
If they’re all coming due basically the same time, then the VC’s observation can be correct and misleading.

@lispi314 @emily_s @gardengeek @samueljohnson @schratze lots of interesting observations thanks. To hopefully unconfuse: the only important metric is the absolute number for fossils. If that doesn't come down we're fucked.
It's going up, globally, at record rates, also for China.
My guess is that the main reason for this detail is that we're outsourcing production to China, instead of consuming less, and another wild guess is the main culprits still are cement and steel.

Then I suppose you can thank the USA for their recent war. That’s going to accelerate divestment of fossil fuels in a lot of places.
Price will have doubled before long and won’t go down nearly as fast. That changes a lot of calculations on switchover.

@lispi314 there's always some asshole I can blame, I'm sure. And the #epsteinClass are usually excellent targets for that.
But today I'll just plant some trees first

They probably expected it from literally all major sources of fossil fuels not within their borders.
I would feel comfortable speculating the turn to solar is long-term strategy for decoupling internal stability from external shenanigans.
They would also very well know the downsides of coal-based generation on health & such.

@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. -

edit: Apparently injecting CO2 into concrete as it sets mineralizes it on the spot which is interesting to know, I suppose.@lispi314 @emily_s @gardengeek @samueljohnson @schratze short term we should just use less of it, long term carbon itself provides materials far superior to concrete and steel.
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
