IT’S NOT ZERO…
WHAT’S THE RIGHT COST?

INSULTS
To Physical Health and Human Environment Resources Used (land, water, energy) Material Effluents (Nox, SO2, CO2) Other Physical Transformations (dredging) Socio-political Influences (politics,
employment)

PATHWAYS
Convert Insults to Stresses Media (air, water, ice, soil, rock, biota) Processes (evaporation, diffusion,
conduction)

STRESSES
Physical or Social Consequences of Insults Magnitudes of Consequences Temporal Distribution of Harm Spatial Distribution of Harm Coincidence of Risks and Benefits Scaling (linear or nonlinear) Resistance to Remedy Irreversibility Visibility of Harm

DOING THE MATH
EC= EF x HR x VED
EC = Externality Cost in ¢/kWhEF = Emission Factor, in lbs/Btu of fuel
consumedHR = Heat Rate of power plant, in Btus/kWhVED = Value of Environmental Damage, in ¢/lb

PITFALLS IN ANALYSIS
Inconsistent Boundaries Average v. Marginal Comparisons Illusory Precision Stochasticity “What’s Countable v. What Counts”

IMPLICATIONS FOR BENEFIT/COST Estimating value of externalities
challenging and not strictly necessary Societal Cost Test problematic Total Resource Cost Test more
conservative and, at this time, sensible Many states have years of experience,
results Ratepayer Impact Measure: Would new
generation withstand this test? Emphasis on lower bills

EFFICIENCY AS A RESOURCE
Efficiency is properly treated AS new generation assuming: Verified, permanent reductions Performance standards
Reasonable savings estimates: Years of empirical savings data by program is available
Ratio of benefits:costs – 2:1 or even 3:1 has been achieved elsewhere As long as efficiency is the least cost
resource, it should be pursued

If we choose not to provide incentives for investor-owned utilities that, added to avoided costs, rival ROI for new generation, then we need to look closely at the following map:
Perverse Incentives
