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.
Paper notes – Mitigating Curtailment and Carbon Emissions through Load Migration between Data Centers
This is a good paper that makes valid points about the possibilities of migrating flexible IT workloads, however it makes classic assumptions I see in most papers that discuss this topic.
The scientific journal, Joule, has published a paper I’ve co-authored reviewing data center energy estimates between 2007-2021.
Is cryptocurrency / Bitcoin bad for the environment? In 2019 crypto consumed 70-90 TWh of electricity globally, with 60-70 TWh of that from Bitcoin mining. What that means for carbon emissions depends on where the mining happens.
The methodology is invalid, which the authors acknowledge but ignore. This means the results of this article aren’t particularly useful.
Using a marginal emissions-based sustainability score incentivizes migrating workloads to a region with a lower marginal emissions factor. The emissions factor for that workload would reduce, but does it incentivize the deployment of new clean energy?
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?
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.
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.
