a quick fix. But if we are to heed the evidence of global climate change and its potential economic and social effects, and if we believe that energy efficiency can help mitigate them, it would be worthwhile to step up the task. Now more than ever it would be wise to take the long-term view and remind ourselves that for now energy efficiency remains, as a 2010 McKinsey & Co. report puts it, “a compelling global resource.” 26

The distributional impacts of energy efficiency can be mitigated with creative programs that offer new products and services to a broad spectrum of consumers. Policy makers and regulators interested in adopting a guideline for their decisions might want to consider a simple, three-step process, a variant of which was proposed more than 20 years ago by Gelling and Chamberlin, two pioneers of energy efficiency analysis: 1) implement all programs that pass the RIM test, 2) eliminate all programs that don’t pass the PAC test, and 3) carefully evaluate the distributional impacts of the remaining programs. 27

To some the current conditions presage a decline like what was experienced in the mid-1990s, a time when utilities apprehensive of the stranded-cost implications of open access mostly abandoned – or drastically curtailed – energy efficiency investments. The risks are real and all involve thinking short term. The big questions are what regulators will make of current conditions and how they will react. Implementing new guidelines for screening energy efficiency measures doesn’t require a grand-scale policy overhaul, merely refinements to well-established procedures. But the regulatory process being as it’s, the change is unlikely to catch on quickly.
