The Smart Grid

The biggest problem in the USA with respect to the transition to sustainable energy sources is our old and outdated (aka 'dumb') electrical grid. Why the U.S. Electric Grid Isn’t Ready for the Energy Transition (by the NYT) is a nice visual illustration and explanation of the problem.

The solution? A new smart electrical grid! Sure, that's a big challenge, but ultimately just an engineering challenge. Here's an interesting approach: Solutionary Rail - electrify the railroads and create corridors for clean electrons.
