I disagree, any attempt to shutdown a significant part of our power grid is terrifying to me. We are at a point in our society that we cannot survive without electricity for a large amount of time. Our economy would shutdown, people will starve as easily obtainable food would go away, certain medicines that keep people alive would spoil, hospitals would shut down, and more. We are so deeply ingrained in having electricity that being forced back to not having it at all would likely kill millions before we could adapt. Especially if the attack caused a semi-permanent power grid failure, such as with an EMP.
