| Summary/Abstract |
Mountainous areas have particular characteristics, whose influence on energy planning is explored in this paper, through a suitably tailored methodology applied to the case of Greece. The core element of the methodology is a linear optimization model with a “total cost” objective function, which includes financial, as well as external costs and benefits. Altitude proves to have decisive influence on energy optimization results, because it affects energy demand. The improvement of local energy systems provides greater socioeconomic benefits in mountainous settlements, due to the high shares of renewables and energy efficiency interventions in the optimal solutions. Energy poverty can be alleviated by redesigning local energy systems and the structure of the energy market. However, spatial and aesthetic restrictions, presented often in mountainous settlements, may affect the operational costs of energy systems, which is a crucial parameter for confronting energy poverty. Furthermore, the study indicates that it could be better to electrify remote areas, far from electricity grids, by decentralized systems than by grid expansion. The results of this study and the assumptions made about the way in which energy market should function, could be utilized for reconsidering energy policy measures, aiming at supporting sensitive societies to improve their development perspectives.

| Summary/Abstract |
Specific strategies for the energy sector should be a central part of a sustainable mountain policy. However, there is a lack of research on the energy issues of mountainous areas and specialized energy policy measures cannot be effectively supported. The determination of the energy demand in mountainous areas, which is an essential step in the direction of developing mountain energy policy, is analyzed in this paper. Greece has been selected as a case study. The results show that altitude is the decisive factor affecting degree-days and energy needs, within the geographical range of Greece. It is proved that the thermal, as well as the total energy demand are significantly increased in mountain settlements. The annual energy expenditure of a typical residence lying at an altitude of 1000 m proved to be 85% higher than the corresponding cost at sea level. This makes mountainous populations vulnerable to energy poverty. It is also proved that the subsidy policy for heating oil, in Greece, cannot alleviate energy poverty. The results of the present study can be utilized in the direction of re-designing the present policy and this is a completely necessary step for creating a sustainable policy for mountainous areas, in general.
