In this article, we seek to analyze the regional energy policy in the West Pomeranian Voivodeship, with a particular focus on the potential for developing renewable energy from biomass. The article aims to build a mathematical model of the regional energy system, related to the strategy of sustainable development in the region. Taking into account the potential for biomass development and the sustainability criteria, this paper presents a case study of sustainable regional energy planning and implementation in the selected region in Poland. An example of optimizing biomass for renewable use at the municipal level is valuable, as the use of biomass energy requires knowledge of landscapes, energy options, and different stakeholder perspectives. Thus, “energyscapes,” a complex spatial and temporary combination of energy supply, demand, and infrastructure within the landscape, can be very useful in this context. Ongoing research contributes to the development of knowledge on promoting renewable energy sources at the local level and supporting a fair transition to low-carbon energy through energy citizenship and the development of sustainable low-carbon communities at the regional level.
