Renewable energy sources are amongst the more widely acceptable options for the future transformations of existing energy systems. The complexities of such transformations call for various comprehensive preparatory actions. Amongst them, the organisation of a multifaceted renewable value-chain into a renewable network may well be crucial for the successful utilisation of renewable energy sources in the future. This paper proposes a novel concept for renewable network covering entire renewable value chain with division on supply, demand and technology sections. In the past, each section has been addressed separately. The organisation of renewable network covering all sections is deemed to be vital for accomplishing the optimal distribution and deployment of renewable energy sources. Constant technological advancements within the renewable sector indicate the significance of a technology section within a renewable network. The appropriate arrangement of various stakeholders involved throughout the entire value-chain, which includes all sections of a renewable network, is therefore crucial for the further development of a renewable sector. The proposed concept of a renewable network would support the effective operation of a renewable value-chain within a municipality through the establishment of local virtual energy cooperatives aimed at fulfilling energy needs and supporting the development of the community. The applicability of the proposed concept is demonstrated through the development of a biomass network within the municipality of Cirkulane, Slovenia. © 2013 Elsevier Ltd.

The way forward clearly orients us towards the decarbonisation of energy systems. Sustainable energy systems ensure fewer burdens on the environment and consequently provide success when fighting climate change. Energy policy provides support in addressing the present energy challenges. Municipal policy has often been neglected, with greater emphasis being concentrated at the centralised level. In addition, another identified problem has been the insufficient quality of the municipal policy performance with lack of acknowledging various features within the municipality. Therefore, the presented paper focuses on the constitution of municipal energy policies that include all aspects of municipalities' energy systems and lead towards less environmentally burdened energy systems. The main objective is to enhance sustainable development within municipalities through constitution and integration of suitable municipal energy policies. The proposed paper presents an entirely inclusive process for a municipal energy policy's institutional, implementation and evaluation phases. Municipal energy policy has to enable maximum efficiency of energy systems by implementing customised targets and measures. This novel methodology for integrated municipal energy policy constitution and integration has, in fact, been applied within the Podlehnik municipality, representing one of the small municipalities in Slovenia. This work proposes an important step towards formalising a municipal energy policy constitution and integration process. © 2016.

Effectively implementing various energy and environmental policies contributes to the acceleration of energy performance, a reduction in negative environmental impacts, and increased deployment of renewable resources. The MEEMS (municipal energy and environmental management system) performs the almost inconceivable role of accomplishing prerequisite targets at the national level and, consequently, the European and World levels also. Therefore, a proper infrastructure for MEEMS needs to be effectively applied in order to implement policy initiatives. A novel organisational framework of MEEMS is proposed and is constituted upon three pillars: integration of the municipal metabolism approach, the KBS (knowledge-based system), and the MTIS (municipal technology innovation system). By properly addressing the dynamics of the MEES (municipal energy and environmental system), and the new conceptual organisation of MEEMS, a need for the inclusion of innovative elements can be defined regarding support mechanisms. Integration of the end-user approach defines the fundamental orientation of modern MEEMS. This new concept paves a pathway towards an intelligent energy and environmental system. This paper describes an implementation of the new conceptual design of MEEMS within the urban municipality energy system of Ptuj, Slovenia. © 2013 Elsevier Ltd.

Present day energy policies are increasingly being focused towards local energy systems. Local communities may be more effective when implementing energy objectives due to the lower losses of energy during transmissions, closer contact with the end-users, and also greater support from local decision makers. Different tools, approaches and concepts are available for achieving greater energy efficiency within local energy systems. One of them is the Locally Integrated Energy Sectors (LIES) concept that provides energy integration with end-users from various sectors such as the industry, service, household, agriculture, transport and public sectors within a particular geographical area. LIES could well contribute towards lower energy consumption, novel opportunities for sustainable energy supply, decreased negative impact on the environment and consequently towards the amplification of sustainable development (SD) regarding local communities. The presented research focused on developing suitable metrics for evaluating the sustainability of LIES. These metrics are comprised of general sustainability indicators grouped into four major categories: energy, environmental, economic, and social. The applicability of the proposed metrics for LIES evaluation is illustrated by a case study of the district heating system within the Ormož municipality in Slovenia. © 2014 Elsevier Ltd.

The decarbonisation of energy systems is one of the important issues of the present energy policies. One of the ways of achieving this is to focus on local energy systems, thus ensuring as much as possible their heat and power self-sufficiency by applying local renewable resource integration and transformation of the renewable energy. Increasing the share of renewables within the local energy balance could be accomplished by using a variety of approaches. One possibility is combining the Locally Integrated Energy Sectors' concept with the novel management and organisation of a renewables-based network. As a first priority, the proposed comprehensive approach focuses on increasing the energy efficiency of municipal heat and power systems using the Locally Integrated Energy Sectors' concept, which is followed by the integration of renewable energy sources with the establishment of a renewable-based network. The proposed approach is illustrated by a case study of district heating based on wood biomass for the municipality Ormož, Slovenia by integrating various end-users from different sectors. © 2015.
