And even if we could do all of this it will still leave an 8 TeraWatt average consumption to try to supply.
Looking at Chicago specifically, things like AC, lighting, and most of Chicago's transit are electric already. Changing the source of the electricity won't have any effect on their efficiency. Replacing all the buses and every car with electric will increase demand, not reduce it, as will a rising population. Replacing natural gas heat and water heaters with electric will, again, increase electric demand. There's no way moving away from fossil fuels entirely will decrease demand by more than half as they say it will, and if anything I would expect it to do the opposite.

ETA: In the ads at the bottom of this page, the image for this thread is a still from Mad Max 2. I find that amusing. Someone must have posted it a while back.
