+## Our VMs are low-carbon
+
+- The closest EC2 region to Berlin is eu-central-1
+
+  (Frankfurt; Germany electricity mix: wind, coal, nuclear, gas)
+
+- Instead, we deployed these VMs in eu-north-1
+
+  (Stockholm; Sweden electricity mix: hydro, nuclear, wind)
+
+- According to [Electricity Map](https://electricitymap.org/), they produce ~5x less carbon
+
+  (at least Monday morning, when the VMs were deployed)
+
+- The latency was a bit higher; let me know if you saw any difference!
