At the macroeconomic level, rational policymakers should be trying to maximize total sustainable delivered well-being, which (other things being equal—which they often are not) would mean maximizing the EROI of a sustainable energy system for the economy. The effort to use price signals to find and promote that outcome requires that the relative

infrastructure necessary for a sustainable, renewable energy economy must come from current energy consumption.
