There's also a lot of fun involved, though. There's a biodiesel-powered movie screening, bike rides, a beer-making workshop, and even "solar group showers" (which, unfortunately, I don't have more details on at the moment).
An event like Power Down Week won't make our energy economy sustainable by itself, of course. But it will get people thinking about new ways they can live more efficiently, and that can only help.
