HVDC makes long distance transmission viable, and long links already exist: https://www.statista.com/statistics/1305820/longest-power-transmission-lines-worldwide/ https://www.statista.com/statistics/1305820/longest-power-tr... (The direct distance between eg Paris and Ouarzazate is 2100km for reference.) There's a proposal to link the UK to Morocco directly with a 3800km cable: https://xlinks.co/morocco-uk-power-project/ https://xlinks.co/morocco-uk-power-project/ A private scheme in Australia (Sun Cable/PowerLink) was looking at connecting Australia to Singapore via a 4500km cable: https://en.wikipedia.org/wiki/Australia-Asia_Power_Link https://en.wikipedia.org/wiki/Australia-Asia_Power_Link (It fell apart due to commercial issues rather than technical/engineering ones from what I'm aware.)
