An article going around this week suggests that Green Building is a "social movement" that, like other social movements (prohibition, civil rights, etc.) stands at the precipice of success or failure. The writer argues that green building could easily be "co-opted, repressed, subject to failure, or succeed." In other words, he's arguing that the mainstream acceptance of the need to build energy efficient, low impact buildings is a matter of social choice, not something that "must" happen. I disagree.
