> long-range, high-wattage cabling to connect grids As the parent comment is on Sweden... That's a major discussion in our current politics and energy development landscape. Not south, though... but north. 60% of Sweden's energy production is from hydroelectric dams far in the north, but most populations are down south. So, expanding this connection is the most imminently useful infrastructure investment that could be made. But that wouldn't be enough if we also use that power for heating. The problem is that Sweden's largest energy demand is heating cold, windless winters, while the rest of Europe is also cold. Burning stuff to be warm can only really be replaced by nuclear power, which Sweden has been politically opposed to. Burning trash instead of coal is a pretty decent upgrade from that perspective.
