Without reading the article, I could already see what the problem was.

Unless you have capital to invest, you can’t expand or improve the power grid. That capital can either come from the gov’t–through taxation–or from private industry. If you, personally, have enough capital to do so, you can build a fully off-grid system, so that you aren’t dependent on anyone else. But then if shit happens, you also can’t get help from anyone else. (Also, most houses in urban areas do not have enough square feet of exposure to the sun to generate all of their own power.)

Fundamentally, this is a problem that can only be solved by regulation, and regulation is being gutted across the board in the US.
