By 2012, Green Roofs Might be Considered the Next Ethanol.

Green roofs are like ethanol in that they are too expensive for the resulting benefit and they take resources from other needs. A simple, insulated, white (in the south) roof does as well. And the water-handling stuff is utter superstition. The problem with "gizmo green" as currently conceived is that it is high tech visual biophilia that adds cost. The Original Green reduces cost. Everything green about Seaside (which is extensive) was done because it reduced cost. Are students yet aware that the 21st Century- recently begun- will be principally characterized by the permanent impoverishment of the West? The world needs their energy and not one more generation of bullshit! - Andres Duany, 2012.
