Motors, compressors still are more efficient on AC, for place like American South where air conditioning represent largest segment from electricity expense AC grid remains making sense.
- stephen_g 5y agoYes, but the very most efficient AC motors and compressors motors use variable frequency drives, and you can design a VFD powered by either AC or DC. I still do think AC is still advantageous in a lot of ways for power grids though, just not on that particular point.
