WorldChanging Ally IDFuel.com has a short article up today about the impact of "peak oil" on both the cost of living and product design. It lays out the issues clearly, and has interesting links. I do hope that IDFuel dives more deeply into the question of sustainable design in the near future, however. They've done some good work on that front, and as good Viridians, we know that product designers are the shock troops of social transformation.
