SAN JOSE, CALIF. (March 11, 2009) -- If you want to create a more sustainable world, you need to build better cities. If you want to build better cities, you need to understand the networks that make up cities. And if you want all of those networks to actually connect, you need to improve the "dumb grid" and make it a smart grid.
That, in a nutshell, was the message of the third day of the eTech conference. Perhaps unwittingly, Chris Luebkeman of the global design firm Arup encapsulated the theme in his morning keynote: “We need to build [X] for the elderly population,” he said, “because hopefully, we’ll all get old some day.” His X was cities -- specifically, the need to design cities so that seniors can easily get around without cars -- but X could have been networks, copyright, the environment, energy systems or experimental science itself. Improve the future. Build it better. Here’s how.

The U.S. electric grid is so old and outdated it can't handle the influx of wind power and other intermittent renewable resources. Integrating such sources requires adapting a system that is finely tuned to balance the amount of electricity being used with the amount of electricity being generated with fickle winds.
But there is an even more pressing problem, according to this article in the New York Times: the grid isn't big enough. The wind tends to blow strongest in places, such as North and South Dakota, that are far from where people live and use electricity. And no one wants to spend the millions of dollars it would take to put in a new transmission line (not to mention the legal headache of getting all those rights of way).
