The Clemson Energy-Economy-Environment (E3) Systems Analysis Group sits within the Department of Environmental Engineering & Earth Sciences (EEES). The group’s research focuses on building decision-support tools to reduce the environmental impacts of technology systems and to understand the structural transformation necessary to navigate a peaceful transition to a prosperous and sustainable future. Specifically, we model energy and material resource requirements at three distinct levels: micro, the device/facility level, using engineering-based, bottom-up life cycle assessment and techno-economic modeling tools; meso, the industry/local level, using multi-layer, network-analytic techniques; and macro, the regional/national/global scale, using geographic information systems (GIS) and environmentally-extended input-output models.
