With all the industry shutting down, we now pay people to use electricity at night. This could give rise to some interesting uses, if we could figure it out. Combined with a smart grid, that would mean our plug-in cars would be really cheap.
But having free electricity doesn't save you much. At the cottage I use very little electricity, yet the bills are substantial. That's because the line maintenance is a huge cost, so I pay just to have it available.
