I don’t believe the decision was 100% fact-based. There was something about electrocuting an elephant….

DC lines are more efficient but you loose some energy transitioning from AC to DC and some more at the other end going from DC back to AC.

Obviously this occurs only because we have an AC grid. If the “daily grid” was DC there would be no need to change.

If the run is long enough the losses occurred going AC->DC->AC are recovered and energy saved by using DC over the distance.

There’s a pretty good article on Wiki about High Voltage Direct Current (HVDC).

Plans are underway to lay a HVDC line from Iceland to the UK to bring Iceland’s geothermal and hydro electricity to the Isles and on to Europe. Other HVDC lines are being designed to bring North Africa solar to Europe.

We’ve got two major HVDC lines in the western US. The Pacific Intertie brings PNW hydro electricity to SoCal and the Mountain Intertie was build to be bring Utah coal electricity to SoCal. It will likely be re-purposed to carry Wyoming wind.
