Now of course not all of that is from burning coal for electricity (Poland had a lot of manufacturing and heavy industry), but if you were to decarbonise in general it would make a big difference to us :-)
From next year, all new homes here are required to generate most of their electricity from renewable sources, so we should start to see a big uptake in solar. I think this comes from EU regulations to decarbonise housing, so maybe there is something similar in Poland?
