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.
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?
Customers should now be asking their suppliers for the carbon footprint of the software services they buy.
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?
The ultimate goal is a reduction in emissions, but we can’t analyze improvements without reporting energy per unit of work done.
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.
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?
My remarks from a panel discussion on data center water consumption: Zero water in our data centers by 2030: mission impossible?
