There’s another issue that I’ve never seen discussed. The EPA through the shutdown of coal fired power plants may have sharpely reduced the reserve capacity of some of our nation’s grids for a period of two years or longer until replacement facilities can be built.
I’m not as concerned about transmission as I am about the generation of electricity. A terrorist organization would have an easier job of analyzing and interrupting power generation than trying to damage the transmission lines. We as a country have our ass hanging out, and don’t know it. Homeland Security, AFAIK, has their collective head up its ass on a vital aspect of our energy supply.
In the worse case scenario electricity would be unavailable for months or possibly longer in some areas of the country. Doing that would be less complicated than 9/11.
I am not sure of your assessment of which would be easier t take out or have longer term disastrous effects.
I was concerned to see two articles in a week which spoke of the transformer problem.
Anyone who is out and about or lives in proximity to those things should keep an eye out for people who appear to be casing them, IMHO.
In the meantime, we would do well to not consider our grid superior to everyone else and think it could never fail us. Ask our North-Eastern brethren if they would have some more options if given a Sandy do-over, for instance.
