I don't know if it's worth to mention, but on the roof of the facility that hosts Pyramining there is a PV plant (PhotoVoltaic) of 70KWp, producing a bit more than 60000 kW/h per year . It has been installed previously for other reasons, and doesn't feed equipment directly but injects power into the grid. Pyramining is consuming actually ~25000 kW/h per year, and the whole infrastructure (that exists beside Pyramining) is still under 60000 kW/h per year, so actually I can say it's running on green power.

If Pyramining will keep growing at this pace, this plant will not be enough to support it completely. In order to prevent pollution, I will take actions to expand it by installing PV cells over other buildings. I can't guarantee that Pyramining will always run only on green power, but I will do my best efforts to try.
