Couldn't find a Starter Pack for green computing, so gave it a go! 🌱💻 No doubt it's missing many great ones... please add! Hoping to include anyone discussing environmental impacts of compute (not just pure CompSci), the broader the perspectives the better! #greencomputing

A 7% decline in English birds in just 5 years is astonishing

The web of life is unravelling fast
Wild bird numbers continue to fall in UK with some species in ‘dramatic freefall’
Species index fell by 4% between 2019 and 2024 – although data shows woodland populations beginning to stabilise

The paper describes the outcomes of a case study with energy professionals, revealing several "ironies of energy system automation".

Google doc apparently has inbuilt AI now. Seeing an unfamiliar vertical line, I hovered over it. It suggested that I make some corrections to the blurb I was writing. The first one was to change "Dr. Devezer" to "He".

⏰ Deadline is tomorrow to apply to this reaearch role in Cambridge to work with me to make scientific computing more environmentally sustainable 🌱 part of the very cool (in my totally unbiased opinion) Green Algorithms Initiative
loiclnlg.bsky.social Loïc Lannelongue @loiclnlg.bsky.social · Jan 27

💫 The first role is about understanding computers' energy usage to improve carbon footprint monitoring, studying different computing equipment and tasks (simulations, AI...). A good understanding of computer science (hardware in particular) is a plus!

What is scientists' attitude towards the carbon footprint of their simulations? A mixed bag according to this survey in fluid dynamics: low awareness and low priority, but researchers know it can and should be improved.

Really great work here! @official-uom.bsky.social
arxiv.org/pdf/2501.09314
Screenshot of a paper abstract: Community attitudes towards the environmental cost of computational fluid dynamics research. Miranda van Heel and J. R. C. King from the School of Engineering, the University of Manchester, UK (Dated: January 23, 2025) Numerical simulations underpin much fluid dynamics research today. Such simulations often rely on large scale high performance computing (HPC) systems, and have a significant carbon footprint. Increasing the efficiency of data centers or the proportion of electricity coming from renewable sources can lessen the environmental impact of scientific computing to a degree, but the attitudes of researchers also play a role. There are many choices researchers make which influence the carbon footprint of simulations. To change behaviours around simulation use, it is first necessary to understand attitudes toward them. Here, we present a case study on fluid dynamics researchers based in the University of Manchester, UK. We find a low awareness of the carbon footprint of computations, compounded by a lack of knowledge of the specific hardware used to run simulations. There is a discrepancy between researchers self-declared attitudes towards reducing the carbon footprint of their work, and their actions and choices. Overall, researchers did not consider carbon footprint as important in their decision making, and we found no correlation between the impact and carbon cost of simulations. Improved education and awareness of the environmental impact of simulations is imperative in the interests of the sustainability of this field.

It made our lab think about our own environmental footprints. How could we fight climate change? Thats where the Green Algorithms Initiative started, now led by the amazing @loiclnlg.bsky.social www.green-algorithms.org
