More than perhaps any other company, McKinsey has documented how an aggressive energy efficiency strategy sharply lowers the cost of climate action (see “McKinsey 2008 Research in Review: Stabilizing at 450 ppm has a net cost near zero”).
Today they released their most comprehensive analysis to date of this country’s energy efficiency opportunity, “Unlocking energy efficiency in the U.S. economy.” Bottom line: If this country get serious about energy efficiency — for instance, by passing a climate and clean energy bill like Waxman-Markey — then we can sharply reduce existing emissions at a large net savings to the public and U.S. businesses. McKinsey has a new cost-curve just of efficiency measures:
The width of each column on the chart represents the amount of efficiency potential (in trillion BTUs) found in that group of measures…. The height of each bar corresponds to the average annualized cost (in dollars per million BTU of potential). …
