Structural descriptions of alternative energy futures

Long-range energy policy analysis requires a mechanism for characterizing key structural features of a nation's economic system. It is shown that energy-analysis techniques are well-suited to such applications, particularly over time horizons beyond the reach of econometric methodologies. Trade-offs between aggregation and uncertainty are discussed as a function of time horizon. For alternative energy futures, special attention is given to the assessment of impacts on lifestyles, technology, and employment.
