Electricity Demand Response / Micro Grids. Right now, most electrical systems, even internet connected ones, don't have any awareness of electrical supply and demand. Most of the grid is designed for power to flow one direction.

As we bring more intermittent power supplies onto the grid, things get harder. The batteries in electric cars are a small, but growing storage capacity that currently can't flow "backwards". Hardware will be a large part of this, but software will be needed too.
