All states have the ability to generate power. Because the power grid crosses state lines does not mean a state cannot secede. Other countries share power grids peacefully. You comment was and is just stupid. Secession does not mean war.
And you called my comment stupid? lol, too funny!
Undoubtedly the most important infrastructure in todays world is the POWER GRID. No state can independently exist if it's power grid is controlled by some other state(s). It would be foolish to even attempt it and pretty much guarantee a return to 18th century for a sizable number until an independent grid could be built.
