- RECs cannot be used to back claims of 100% renewable energy ()
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
- Data centre water consumption ()
An examination of the water consumption of data centres, the measurement of that consumption, a discussion of the lack of data available to assess water efficiency, and where the industry is going in attempts to reduce future consumption.
- My new startup – Console – the best tools for developers ()
What’s next? 1) Console – a free weekly email digest of the best tools for developers; 2) researching sustainable computing at Uptime Institute.
- Carbon footprint – laptops vs servers, Intel vs ARM ()
The carbon footprint of a laptop is mostly in the manufacturing. Servers are different, and ARM chips are starting to change the game.
- Sustainable computing – where to focus? ()
Progress in renewable energy has pushed IT carbon footprints down, revealing how much more work is needed in manufacturing.
- Zoom, video conferencing, energy, and emissions ()
It is obvious that Zoom is better for the environment than flying but what about vs driving an EV or public transport? The problem is we can’t be sure.
- Spectrum of transparency ()
More rigorous transparency regulations for negative externalities to force companies to measure, and reduce.
- Fighting over who has the greenest public cloud ()
Public cloud price wars have ended, and a new battle over who is the greenest has begun.
- How much energy will 5G consume? ()
5G networks have larger antennas, larger bandwidths, and higher base station density. This means up to x3 more energy consumption. How can the industry expect x20 more energy efficiency by 2030?
- Assessing the suitability of the Greenhouse Gas Protocol for calculation of emissions from public cloud computing workloads ()
