- 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 ()
A copy of my paper published in the open-access Journal of Cloud Computing.
- Hiding greenhouse gas emissions in the cloud ()
The scientific journal, Nature Climate Change, has published a paper I’ve written about how moving to the cloud can result in greenhouse gas emissions being hidden.
- How much water do data centers use? ()
US data centers are expected to use 660 billion litres of water in 2020. In 2018, Google consumed 15.79bn litres and Microsoft 3.61bn litres, primarily for their data centers. What is this used for and how does it impact the environment?
- Energy efficiency, edge compute and serverless ()
We want to encourage more efficient use of cloud resources but designing incentives is hard. That changes with serverless and edge compute. Now energy usage is linked to price.
- Carbon emissions aware cloud compute ()
The first example of carbon aware compute is uniquely suited to hyperscale cloud environments. It becomes even more interesting with carbon aware load balancing and serverless.
- The environmental impact of buying a new laptop – comparing the MacBook Air and Surface Laptop ()
Apple produces the most environmentally friendly laptops from both a carbon footprint and energy efficiency perspective, but it depends on which model you compare. The best thing you can do for the environment is to not buy a new laptop.
- Data center energy and the importance of efficiency ()
Data center energy usage has only grown by 6% in the last decade. How important have efficiency improvements been for decoupling energy from growth?
