Data centers are not 100% efficient, so they generate waste heat, which causes anthroprogenic heat flux, and can therefore be linked to global warming. But how much? And should we be concerned?

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.

Most data centre owners have received the message about reducing their carbon footprint and the transition to renewable energy. We regularly see new projects announced with net-zero carbon goals. They now need to do something similar for water.

There are currently only two credible estimates for global data center energy consumption: 196 TWh to 400 TWh for 2020. Why do we see vastly higher reports?

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?

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?
