Dominic Bednar Research Assistant

Dominic’s research explores the institutional barriers of energy poverty recognition and response in the United States whilst considering the spatial, racial/ethnic, gender, and socioeconomic patterns of residential energy affordability, consumption, and efficiency. More narrowly, his doctoral research aims to provide clarity for structuring more effective policy interventions and to improve decision making for assisting energy-vulnerable households, those likely to fall into energy poverty and struggle/unable to pay their energy bills resulting in energy utility shut-offs and forgoing basic necessities. Dominic is developing a multidimensional energy vulnerability index to better understand factors that contribute to household energy poverty in the U.S. Additionally, Dominic’s research uses LCA and LCC methods to better understand the effect of household appliance replacements on overall energy affordability of low-income households.

The second research area, "Ethical" Urban Consumption and Commodities, focuses on the interrelationships between the consumption of consumer products, our responsibilities as global ‘green’ urban citizens, and the role of governance mechanisms and frameworks (including local institutions) in regulating product consumption. His research approach is often multi-scalar and integrative and, in addition to theory and method found in geography and urban planning, he draws upon principles and tools of industrial ecology (e.g. footprinting and life-cycle analysis), and spatial analysis (e.g. land use/land cover change).
