It's not purely electricity-based, your greenwashing statements are based on a false premise/assumption [0][1].
Secondly, Sweden is an exporter of electricity to the EU, the huge undersea transmission cables are for selling electricity to the detriment of ourselves as shown after the Russian war against Ukraine when we had to pay the massively higher spot prices for electricity set by the gas/coal plants in Poland, and Germany. You can check right now that Poland is importing ~2-3% of its electricity from South Sweden (SE-4) [2] using 98% of the available transmission, Poland is always saturating the undersea transmission from Sweden with imports.
