To determine how much commercial building energy can be saved at what cost, we created an efficiency supply curve.
The supply curve includes both electric and natural gas efficiency measures. For each end-use, the supply curve includes all the measures available and considered for that end-use. The costs in the supply curve for each end-use are an average of the costs for the measures weighted by their savings.
