0933837威廉姆斯本研究的目的是通过开发和应用新方法来推进替代能源技术进步的建模，以（1）估计经济和环境绩效的长期界限，（2）评估生命周期的经济和环境成本，（3）评估技术预测的不确定性。 该方法将协同整合经验曲线、热力学和生命周期方法。 将这些方法联合收割机的概念是（1）挑选实现给定供应类型的生命周期技术路径（例如，（2）应用热力学和物理定律找出效率的上限，（3）对技术的长期成本和环境影响进行下限估计，（4）确定成本和关键环境影响动态演变的技术组成部分的范围。 确定未来技术发展的特点涉及重大的不确定性，对这种不确定性的评估是该项目的一个主要组成部分。 在高中一级，将编制和实施能源扫盲课程材料，其中包括工程/技术方面以及对能源系统、人类社会和环境之间相互联系的理解。 为了促进在决策中对技术进步模型的理解和使用，将在华盛顿附近举办一个讲习班，让能源研发和政策界参与。 该奖项由CBET/ENG环境可持续性和能源可持续性项目共同资助。

0933837WilliamsThe objective of this research is to advance modeling of technological progress of alternative energies by developing and applying new methods to (1) estimate long-term bounds on economic and environmental performance, (2) assess life cycle economic and environmental costs, and (3) assess uncertainty in technological forecasting. The methodology will synergistically integrate experience curve, thermodynamic, and life cycle approaches. The concept to combine these approaches is to (1) pick life cycle technological paths implementing a given supply type (e.g., cellulosic-based switchgrass ethanol), (2) apply thermodynamic and physical laws to find upper limits of efficiency, (3) develop lower bound estimates of long-term costs and environmental impacts of technologies, and (4) scope technological components of dynamic evolution of cost and key environmental impacts. Characterizing future technological development involves significant uncertainties and assessment of this uncertainty is a major component of the project. At the high school level, curricula material will be developed and implemented for energy literacy that incorporates both engineering/technical aspects and an understanding of the interconnections between energy systems, human society, and the environment. To advance the understanding and use of technological progress models in decision-making, a workshop will be held near Washington D.C. to engage energy R&D and policy communities. This award is co-funded by the CBET/ENG Environmental Sustainability and Energy for Sustainability programs.
