The environmental footprint of social media hosting: Tinkering with Mastodon
www.easst.net
A growing body of literature on waste and discard studies has crafted a powerful critique of waste management and politics (Callén and Sánchez Criado 2015; Liboiron and Lepawsky 2022; Gille and Lepawsky 2022; Ek and Johansson 2020). In today’s dominant waste regime, waste is naturalized as a burden

Social media platforms need a lot of computing and storage power provided by energy-hungry data centres that constantly have to upgrade their hardware, spitting out vast amounts of e-waste. This is particularly true of commercial platforms with their ML-driven ad systems. The fall of Twitter and Reddit would be beneficial in that regard.

But what about Fediverse systems? The link discusses Mastodon, but that’s only one example. Would it be possible to host Lemmy instances in a sustainable way? With solar power? And what would it imply, materially and socially?

I have resources like the Low-Tech Magazine in mind, which uses solar power to host a website. The downtime is part of the adventure. Or we’d have to deploy a solar protocol to use the earth’s rotation creatively and for cooperation.

    What is often omitted is that large centralized data-centers need a lot of cooling. Due to efficiency improvements this has somewhat improved lately, but it used to be up to 60% of the total electricity used.

    Smaller decentralized servers don’t need nearly as much of it as they can easily dissipate heat to their cooler surrounding even if they use older less efficient equipment.

    Thus up-cycling older server hardware in decentralized locations can save a lot of energy if you consider the entire life cycle of the equipment.

      I agree with this. Efficiency vs cooling the infrastructure and updating hardware after a maximum of 5 years. Still, I’m not 100% sure about statistics. Do you know of any comparative studies or the like?

      Just one fitting side note. We had an interview with a local data centre manager and during the discussion, we somehow started talking about alternative setups, like a raspberry pi server. The interviewee reminded us of the efficiency of their virtual servers. He even gave us a tour through their digital dashboards and showcased the 1 watt used by a server (vs roughly 4 watts of a Pi, with much less performance).

      This is not to say that low-tech is not the way to go. Less mining and hazardous work conditions are always good and need no measurement for emphasis.

      Also omitted - the amount of speculative buying for planned capacity that never actually happens. I worked for one of the big tech companies for several years, and more specialized hardware especially (ML accelerators) were spun up with the notion of “we don’t know who will need these, but we don’t want to not have them if they’re needed”. Cue massive amounts of expensive hardware sitting plugged in and idle for months as dev teams scramble to adopt their stuff to new hardware that has just enough difference in behavior and requirements as to make it hard to migrate over.

      Also also, there’s a bunch of “when in doubt, throw it out” - automated systems detecting hardware failure that automatically decommission it after a couple strikes. False positive signals were common, so a lot gets thrown out despite being perfectly fine.

      There are actually quite a few projects to use waste heat from data centers to heat homes. With aquifere storage that can even be used in a seasonale fashion.

        Not fully. Well, I am pretty sure most of the power comes from the nearby geothermal plant and the three windmills up the hill, but overall the grid power here is still around 50% fossile.

        I started building a solar PV system for it though, but ran into some issues with the batteries that I am still trying to solve without having to buy expensive new ones.
