[Off topic] but allow me this remark:
I don't know where you learned that, but you have to take it out of your head. No, the alternative does not cause less loss in the cables than the DC, it is even rather the opposite because of the skin effect of the alternating current.
It is not for nothing that future high voltage / long distance link projects are planned continuously (HVDC)
Historically the alternative is not used for reasons of losses, but for reasons of ease of transport (easier to transform)
You probably confuse between mono and three-phase ... with equivalent cable section, the three-phase allowing to pass 9 times more power than the single-phase.

Now yes, I had seen the missouriwindandsolar wind turbines ... they are interesting from all points of view but the import remains problematic for an individual. Once removed the costs of transport and customs, the difference is not obvious ... and then in case of problem hello the puzzle (and costs ...) to play the guarantee.
