  • Three Decades of Climate Mitigation: Why Haven't We Bent the Global Emissions Curve?
    • High emitters (whether countries, organizations, or individuals) are often the least vulnerable, weakening direct incentives for action, while those least responsible for emissions often suffer the worst impacts.
    • Combustion of fossil fuels and large-scale land-use change have underpinned economic development over more than two centuries, creating deep path dependencies (not only economic but also material, social, cultural, and psychological).
    • Dominant economic and political interests are invested in the status quo and work hard against change.
    • Causes are also deeply embedded in wider economic and geopolitical divisions, including the historical backdrop of colonialism, imperialism, and other systemic injustices.

  • "AI is fueling a data center boom. It must be stopped., by Paris Marx Feb 9, 2024
  • 2024 toots:
    • The electricity and water use required by data centres is becoming cause for concern. Iowa and Ireland are calling for moratoriums on new development projects. Microsoft’s global water consumption grew 34% from 2021 to 2022. And estimates say that around 80% of content in data centres could be stuff we never use again, stored by default to consume energy in perpetuity for no purpose at all.
    • Denmark: “the reason of the data centers in denmark, in this case facebook in the city of Odense is: 
1)stable energy source 1.a) with high level of renewables. 2) Proximity to the backbone cables 3) Skilled workforce in the construction process (though the proces was run in a way, were there was a high level of control, and very little trust in the skilled workers..., so maybe thats a stretch) 
4) low levels of naturcatastrophes (erathqueakes etc.)
5) stable water source . The reason are laws regulating the area, so the potential expenditure from reusing the heated water, may never affect the prices. So, as i understand it, prices should be kept as low as possible and be on marketlevel and competitive, and saved energy for an economic cost is not a argument to raise prices. So the situation is that facebook have som semi-heated water, that needs further heating to be usable to send to homes, so it in reality it wont be free heating, there still needs to be heated on the water, so the result from an economic perspective is that there is no businesscase for the investment, which means it will be an expenditure in the short run, which means its not legal - even though it makes sense purely energy wise/ reality. The result is that the laws are maybe good intetions, but in a situation where investments and innovation is need, they dont make sense. And the article describe that they are rightly critized for that. 
The question is the if facebook knew that, and speculated in it, and/or in the proces has acted in a way so it would be the end result; to be stopped by those laws. 
And thats an analysis that needs to be made and documented, if so. 
But:heating was promised before, and heating is not now. 2020/Before:
"Our datacenter in Odense will generate heat at a level not reached anywhere in the world"
"Facebook confirms:heat on its way to 6900 houses in odense". Now: no heating:
