Electricity use is only one part of energy consumption. Transportation costs, production costs, and even food generation are all included in the umbrella. Also, "costs" aren't just referring to dollars spent, but also environmental impact. Having cheap electricity is only a small part of the equation, and barely a relevant one at that.

Energy is roughly transferable - if you have cheap electricity you can use it to produce cheap process heat, synthetic fuels, food, environmental cleanup, etc. You get enough solar panels for a low enough price and all the other problems become trivial.
