The proposed sale of GM’s Hummer brand to a Chinese company fell through this week, and GM will now shutter the company. The ultimate symbol of overconsumption has finally fallen prey to higher energy prices and changing consumer demands. This New York Times piece offers some interesting stats, like the fact that Hummer sold only 9,000 vehicles in 2009, even when energy prices dropped back down.This is just another piece of evidence to support what I’ve written before here, and in my book Green Recovery at length: that the Detroit automakers missed the green wave — rising energy prices, resource-constraints, and changing demands for more energy-efficient products.
