Distributed generation, rather than one gigantic grid, lots of separable microgrids. Pretty smart
We do not have one giant grid in the US. There are several power pools, each with a different “phase angle”. People who work in power plants will know what I am talking about.
The only way to interconnect with theses power pools is to convert your AC to DC, then back to AC on the other gird.
in some waysyes, others no
