Devil's advocate time, well not exactly, but this might be a silver lining thing.
Power is more than how it's made. It is also about distribution and what never gets mentioned is that grid technology is obsolete for many purposes. It requires a heavy investment in an increasingly vulnerable system. The real hacking concern revealed wasn't dirty laundry aired, but code found on power company systems. It is very possible that terrorists or governments can take down grids and that's the definition of disaster.
Let's assume that Wyoming does what it says it will. Renewable is becoming cheaper and this act will drive solar forward but off-grid. In some cases a cluster topology where communities share power but are isolated from a main grid may make sense, or stand alone systems which would be quite immune to hacking would become the preferred method of power generation which means that less coal is used and even light industry can use an alternative. The poor suckers which are stuck are those in heavy industry which has a high energy requirement, but for the most part the electrical utilities are irrelevant and the state significantly more resistant to tampering.
Wyoming might just have the most advanced electrical power scheme in the nation. Perversely true, but might happen.
