Microgrids can capture the key virtues of the Internet using a similar topology
Microgrids will create a massively distributed mesh network of system sources, storage and loads

Definition:
The Enernet:Flexible, clean, efficient, resilient, affordable
and sustainable energy infrastructure
Enernet" refers to the global power system that -- (i) is logically linked together by a
globally unique intergrid connection scheme applied at the points of common
connection between grids; (ii) is able to support transactionally based flow control
protocols based on the principles of free-market trade to achieve a balance of the
supply and demand for electricity; and (iii) provides, uses or makes accessible, either
publicly or privately, high level services included with the electric power infrastructure
described herein.
