Abstract
Integrated energy and urban mobility systems are key components for achieving
cities’ sustainability. Several urban metabolism approaches are emerging as
leading tools for quantifying energy consumption and use patterns of resources
in urban environments. Examples are the mass balance accounting (or energymaterials
flux approach) using several quantification methods such as material
flow analysis and life cycle assessment and Odum’s emergy methods. In this
research we adapt the extended metabolism model of a city developed by
Newman (Sustainability and cities: extending the metabolism model 1999) and
the material and energy flow accounting by Sheeri (UK material flow accounting
2002) to assess the future role of electric vehicles, renewable energy use for
mobility needs and energy efficiency increases for households living in the city
of Aveiro, a medium-sized city of 78,450 inhabitants in Portugal. The data used
comprised an integrated set of energy, transport, socio-economic and solid waste
production/treatment collected at the local and National level as part of the
research project COST-TRENDS funded by the Portuguese Foundation for
Science and Technology. The analysis of the potential energy mix (energy inputs
from different sources) and households’ mobility needs refers to the horizon
2010–2020. Several energy sources were considered: hydric, wind, solar
(thermic and photovoltaic) and solid waste (incineration and biogas). Potential
accessibility indicators were developed to better converge towards sustainable
mobility objectives, measuring the potential for interaction and exchange of
services and opportunities. Different household’s profiles were established to
represent consumers’ behaviour. It was found that the above integrated energy
