In an increasingly interconnected, and electricity-reliant world, households are asked to build up their resilience to crises. Local, distributed electricity production within a microgrid with capability to operate disconnected from the larger grid has been shown to be an effective tool for increasing power system resilience in the past. The energy production of local renewable sources is, however, not sufficient in meeting normal household energy demand.

This thesis explores whether the forming of communities can be utilised to reduce energy demand and as a result, increase the resiliency of both the community and urban environments.

The analysis of household energy use and the subsequently developed toolbox provide insights into energy use both under normal societal function and during a crisis. Through living and cooking together as a community, significant energy-efficiency gains were possible, exceeding those reasonably achieved within each individual household. Community was further determined to be important in the planning and development of more resilient combinations of renewable energy, going beyond solar power. When implemented in theoretical scenarios, energy communities at a building and block level could provide sufficient energy for the households’ most immediate needs without major sacrifices of wellness.

The scheme proposed is argued to require not only monetary investments, but also larger societal shifts. Producing sufficient quantities of electricity within urban environments will mean a large change in how cities are experienced. Public understanding and acceptance for such a change is likely to be necessary. Through the implementation, the role of the municipality would go from action-taking to mostly laying the groundwork for the formation of communities, as well as advising these as they achieve higher household resilience. Most critically, however, there is a need for the broader population to embrace working together in communities.
