It's a great idea, but won't they go broke doing it?

I mean, I realize the price of gasoline is kept artificially low in the USA, and by extension, I'm guessing the same is true for other energy costs - I know fuel extraction and insurance are heavily subsidized. But the maximum rate we pay at home is $0.114 per kilowatt-hour - plus a couple of flat monthly charges, so the actual effective rate is a little bit higher, but not much. And I know that commercial electric rates are higher in the USA than residential. But €2.6 per 10 watt-hours is thirty times my highest rate.
