I watched the whole video, and see where the idea that tree huggers caused the problems came from... the push to spend $$$ on renewables. The problem is, PG&E would not have spent the $$$ on maintenance anyway! They have been neglecting their own infrastructure for decades.Thanks. I can never have too much information. Here is an interesting piece that Jack Rickard found on PG&E..
You know how he described the idea of bureaucrats and bean counters rather than technically competent people making decisions? The idea of using insulated wire on poles is one of those choices. It looks good to the public that doesn't have any technical knowledge "wires need insulation, everyone know that!"... but unprotected insulated wires are a maintenance nightmare. They are vulnerable to every form of erosion to the insulation you can imagine, and some you wouldn't think of! In addition they are much heavier, much more expensive, and not even a little bit safer. As he said in the video, every pole, every transformer, every bit of the system where that crap is installed will have to be replaced.
The Bureaucrats would rather look good to the public by wasting the $$$ than spend the $$$ on real infrastructure repairs and improvements.
PS: Good video! It explained a lot.
