    The vast bulk of electrical power transmission is AC. DC is sometimes used but only for VERY long haul distances, which is relatively rare. Mostly between grids (in the US there are only three major grids) where the AC is un-phase synchronized between grids.
    1. very long distance is exactly of which I am referring. BPA (Bonneville Power Administration) which includes, but might not be limited to, several major producing dams on the Columbia River transmits with DC to California. I've toured several of these dams btw.
    2. 100% of my electric power comes from Columbia River dams
    3. What are the three major grids?
