IT Energy

An example of poor quality research with flawed assumptions designed as click-bait to get news coverage timed to land during COP26. Deleting a few photos will have zero impact on your carbon footprint.

Sustainable computing concerns the consumption of computing resources in a way that means such usage has a net zero impact on the environment.

What will drive computer performance after Moore’s law? Will programmers need to focus on performance or can ARM chips and the cloud save us?

It is currently impossible to properly compare how sustainable one product is vs another. Pictures of wind farms look nice, but how do you choose which cloud region to deploy (or move) your resources if there is no way to compare them?

My remarks from a panel discussion on data center water consumption: Zero water in our data centers by 2030: mission impossible?

As more applications are run through a web browser, even that is beginning to be streamed from the cloud. Is that the best use of our now highly efficient computers? How energy efficient is application streaming?

My notes on the paper: Syed et al (2021) An Analysis of Renewable Energy Usage by Mobile Data Network Operators. Sustainability. 13 (4), 1886.

My notes on the paper: Bol, D., Pirson, T. & Dekimpe, R. (2021) Moore’s Law and ICT Innovation in the Anthropocene.

Most data center sustainability strategies still focus on renewable energy certificates (RECs). RECs are now considered low quality products because they cannot credibly be used to back claims of 100% renewable energy use
