There's a lot of power loss in transmission over long distances. China is attempting to move power from solar fields from the eastern deserts to its major cities using Ultra High Voltage (UHV) power lines [1], but not without problems.

- jhayward 6y ago> There's a lot of power loss in transmission over long distances. No, there's not. If one were to build new transmission today one would expect low-single-digits percentage loss per 1,000 miles of distance. It's not enough for anyone to worry about.
- gehsty 6y agoHVAC has significant losses, HVDC has less losses and allows power to be transmitted efficiently enough over long distances (guess it depends on what you mean by long). A good example is North Sea link, linking the north of England to the abundant hydropower in Norway, which should come online this year I think. HVDC links connecting European countries of the length 400-600km are becoming quite common, unfortunately subsea cables are prone to failures and can cause a lot of outages etc.
