Initial Emissions Monitoring of the OCaml.org Infrastructure

The library used for accessing emission information from electricity grids called “carbon” should now be available on opam. This is an initial release and might change a bit (e.g. it depends on an alpha release of cohttp-eio).

opam update && opam install carbon

Here’s a simple example to get the emission numbers for Great Britain.

Eio_main.run @@ fun env ->
Mirage_crypto_rng_eio.run (module Mirage_crypto_rng.Fortuna) env @@ fun _ ->
Carbon.Gb.get_intensity env#net
|> Eio.traceln "%a" Carbon.Gb.Intensity.pp

Thanks to @emillon for providing a backend for French data and to @reynir for suggesting important changes to the CO2-signal backend before the release.
