Nice article.
I feel though that, as many others, it compares the carbon footprint of production (panels and batteries) vs the footprint of burning only. By looking at the source of the carbon footprint, it seems that they take into account only the CO2 output of the energy factories, but extraction, transportation and storage has a non-negligible carbon footprint.
The opposition received 55% of votes all combined, while Law and Justice was the single party receiving the most votes. So effectively, unless all other parties would get together in a single big party (making a very different election), Law and Order would now be ruling Poland and instead the opposition parties formed a coalition.
