Overestimating AI’s water footprint
Researchers need to be more careful about the inputs into their models. Overestimates undermine the goal of reducing the environmental impact of IT.

Paper Notes – The world wide web of carbon
Will we ever be able to accurately assess the carbon footprint of IT? Could a relational footprint methodology be more useful? Paper notes on Pasek et al (2023).

Improving the accuracy of the GHG protocol in time and space
The GHG Protocol needs to evolve to better represent the complexity of how energy markets work.

Influencing the carbon emissions of AI
There is a correlation between the training time and energy consumption, but that doesn’t mean there is a correlation between training time and carbon emissions.

Why don’t data centers participate in demand response?
Demand response is where a user of energy (usually electricity) varies its demand for a period of time in response to a request from the grid operator. This typically occurs when demand might outweigh supply. If it is not possible to increase supply in response to higher prices, the next…

Energy systems and 24/7 carbon free energy
With the grid mix constantly changing, what needs to happen to energy systems to reach the goal of 24/7 carbon free energy? Google has funded two studies to find out.

Sustainable dev environments in the cloud
Is it better to replace powerful developer laptops with cloud dev environments? What is the carbon cost of my software development – builds, tests, deploys, code hosting, dev environments?

Carbon aware workloads – current status, limitations, and opportunities
Why isn’t carbon aware workload scheduling more common? Data center level scheduling is infeasible, so what are the opportunities for developers to implement more granular functionality?

Paper Notes – Assessing anthropogenic heat flux of public cloud data centers: current and future trends
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?

Dirty data? Carbon footprint of photo storage
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.
