Thx for your answer...
I am totally convinced that already in the not too distant future this will be a major issue for the whole industry in general as it is currently already for all kind of cloud services etc..
And Poland has unfortunately the most carbon intensive electricity in Europe.
I hope you will come up with a solution based neither on dirty coal nor dirty and unsafe nuclear power but based on clean renewables... as with your mining project..
Do you have any estimate of total power consumption per year?
