The Low-Hanging Fruit Pie

Princeton University researchers have developed the "wedge model" for attacking climate change.  Each wedge is a separate strategy for dealing with climate change.  Although simplistic, the model illustrates the proposition that there is no single approach to mitigating man-made contributions to climate change.  The wedge strategies range from energy efficiency to switching from carbon-intensive fuels to nuclear energy development, and together form a complete strategy for attacking climate change.  I like to think of the model as a pie consisting of wedge-shaped pieces.  Unlike a pie, however, some climate change wedges go down easier than others.  The economics and physical logistics of geologic sequestration, for example, are much more challenging than simple energy efficiency.
