Travel patterns from survey data are combined with naturalistic drive cycles. More realistic PHEV energy modeling using these synthesized real-world drive cycles. Methodology is demonstrated for PHEVs in Michigan but applicable for other regions. Energy and emissions findings have major implications for PHEV standards and policy. a b s t r a c t Plug-in(More)
Purpose This study aims to compare the life cycle greenhouse gas (GHG) emissions of two cellulosic bioenergy pathways (i.e., bioethanol and bioelectricity) using different references and functional units. It also aims to address uncertainties associated with a comparative life cycle analysis (LCA) for the two bioenergy pathways. Methods We develop a(More)
Compared life cycle energy and GHG emissions of wireless to plug-in charging. Modeled a transit bus system to compare both charging methods as a case study. Contrasted tradeoffs of infrastructure burdens with lightweighting benefits. The wireless battery can be downsized to 27–44% of a plug-in charged battery. Explored sensitivity of wireless charging(More)
Electrified vehicles (EVs) couple transportation and electrical infrastructures, impacting vehicle sustainability, transportation resil-iency, and electrical grid stability. These impacts occur across timescales; grid stability at the millisecond scale, resiliency at the daily scale, and sustainability over years and decades. Integrated models of these(More)
DESCRIPTION This course examines the production and consumption of energy from a systems perspective. Sustainability is examined by studying global and regional environmental impacts, economics, energy efficiency, consumption patterns and energy policy. First, the physics of energy and energy accounting methods are introduced. Next, the current energy(More)
