Where did our electric grid come from? It's a complicated question to answer. That's because the grid we have today didn't come from any single place. Instead, its origins are scattered, distributed geographically, technologically, and philosophically.
Different people built different parts of the grid in different ways and for different reasons. For many years—up until the 1970s in some places—individual towns and cities were independent grids that weren't connected to anything else around them. They functioned as little islands, incapable of reaching out for help when things went wrong.
More importantly, the grid wasn't designed. It evolved. Nobody ever really sat down and thought about how to build the best grid possible. The grid as we know it was assembled from bits and pieces, from mini-grids that were often built to be cheap and to go up quickly. Quality wasn't always priority number one.
I think the story of the electric grid in Appleton, Wisconsin—the second centralized electric grid in the world and the first hydroelectric power plant in the world—is a great example of all of this history in action.
Last month, I got to talk about Appleton at a Barnes and Noble in the Bay Area. The video of that talk went up on CSPAN Book TV yesterday. It's not available for embedding, unfortunately, but I encourage you to give it a watch. The talk covers not only history, but also the importance of writing about science online, rather than in print. You guys, as commenters at BoingBoing, have made my writing better—and for that you get a shout-out. (Plus: At the 5 minute mark, you can see a little cameo of Dean and Pesco in the audience.)
