The aim of this paper is to analyze and explore the most suitable energy policy instruments for energy efficiency improvement in Serbia. The analysis has been carried out with a focus on energy indicators for Serbia and EU27. It encompasses a period of twenty-two years and is directed towards the consideration of amendments that need to be made in the National Energy Efficiency Policy. Despite constant attempts to improve and increase energy efficiency and to expand utilization of renewable energy sources, it seems that accomplished results are still very modest. The comparative analysis of the situation in the area of energy efficiency in Serbia and in the EU takes into consideration deficiencies in the energy policy in Serbia and proposed measures for overcoming them. The Multiple Criteria Decision Analysis method is used for analyzing the extent of key influences on success in the implementation of energy efficiency policy in Serbia and also for the interpretation of results. The analysis shows that identified energy policy instruments are such that the success in their implementation will depend on a reformed institutional approach. This method can be applied in any other country.

Improved energy efficiency in supply chains can reduce both environmental impact and lifecycle costs, and thus becomes a competitive advantage in the work towards a sustainable global economy. Viewing the supply chain as a system provides the holistic perspective needed to avoid sub-optimal energy use. This article studies measures relating to technology and management that can increase energy efficiency in the supply chains of five aluminium products made in Sweden. Additionally, energy efficiency potentials related to the flows of material, energy, and knowledge between the actors in the supply chains are studied. Empirical data was collected using focus group interviews and one focus group per product was completed. The results show that there are several areas for potential energy efficiency improvement; for example, product design, communication and collaboration, transportation, and reduced material waste. Demands from other actors that can have direct or indirect effects on energy use in the supply chains were identified. Despite the fact that companies can save money through improved energy efficiency, demands from customers and the authorities would provide the additional incentives needed for companies to work harder to improve energy efficiency.

This paper analyzes energy efficiency in Serbia. The analysis has been done on the basis of energy intensity indicators for Serbia and neighboring countries, and some other countries and regions. It relates to the period of some ten years and it is directed to the consideration of required interventions regarding the change of the National Energy Efficiency Policy. Regardless of constant attempts to improve and increase energy efficiency and to expand utilization of renewable energy sources, it seems that accomplished results are still very modest. The analysis of several energy indicators and their changes in the midterm period confirms this statement.

The main goal of setting energy efficiency priorities is to find ways to reduce energy consumption without harming consumers and the environment. The renovation of buildings can be considered one of the main aspects of energy efficiency in the European Union (EU). In the EU, only 5% of the renovation projects have been able to yield energy-saving at the deep renovation level. No other study has thus far ranked the EU member states according to achieved results in terms of increased usage in renewable sources, a decrease in energy usage and import, and reduction in harmful gas emissions due to energy usage. The main purpose of this article is to perform a comparative analysis of EU economies according to selected indicators related to the usage of renewable resources, energy efficiency, and emissions of harmful gasses as a result of energy usage. The methodological contribution of our study is related to developing a complex and robust research method for investment efficiency assessment allowing the study of three groups of indicators related to the usage of renewable energy sources, energy efficiency, and ecological aspects of energy. It was based on the PROMETHEE II method and allows testing it in other time periods, as well as modifying it for research purposes. The EU member states were categorized by such criteria as energy from renewables and biofuels, final energy consumption from renewables and biofuels, gross electricity generation from renewables and biofuels and import dependency, and usage of renewables and biofuels for heating and cooling. The results of energy per unit of Gross Domestic Product (GDP), Greenhouse gasses (GHG) emissions per million inhabitants (ECO2), energy per capita, the share of CO2 emissions from public electricity, and heat production from total CO2 emissions revealed that Latvia, Sweden, Portugal, Croatia, Austria, Lithuania, Romania, Denmark, and Finland are the nine most advanced countries in the area under consideration. In the group of the most advanced countries, energy consumption from renewables and biofuels is higher than the EU average.

AbstractThe Republic of Serbia must make significant efforts to promote and exploit renewable energy sources and increase energy efficiency in all energy sectors to ensure energy security and economic competitiveness, reduce the negative impact on the environment from energy production and use, and contribute to global efforts to reduce greenhouse gases. Within the paper several issues of integration of recently realized CHP plant are introduced and discussed. Firstly, the legal and energy policy issues in the Republic of Serbia regarding connecting CHP to the grid are presented. The challenges and technical solutions for CHP connection to the grid, as well as power quality issues and the role of the CHP plant during the restoration of power supply during the maintenance of the substation and unplanned loss of high voltage supply, are presented and discussed. Finally, the impact of prospective massive integration of CHP on the energy balance and CO2 emission reduction in the province of Vojvodina in Serbia is investigated and discussed. Since it is the first CHP plant realized in Serbia, it is crucial that experience be shared to all potential stakeholders in the future energy efficiency projects.

Energy Benchmarking

The implementation of energy efficiency measures and use of renewable energy sources in educational buildings can significantly contribute to reducing energy consumption, but also to CO2 emissions in the entire public sector. The paper shows the comparison of energy consumption indicators for 61 elementary school buildings which have previously been divided in 12 groups, according to the period of construction and size, based on the national typology called TABULA, as the first step of further study on how to use the renewable energy sources. The aim of this paper is to use the energy benchmarking process to select representative facilities which are suitable for applying renewable energy sources, for their further energy efficiency improvement. Indicators of annual specific electricity consumption and CO2 emissions per unit area [kWh/m2] and per user [kWh/user] were calculated. After that, from two groups (in which the highest electricity consumption and CO2 emissions are 68.37% and 74.53% of the total consumption/ emissions), one representative facility was selected.

Lack Of Knowledge

We analyze the elements determining the sustainability of nautical tourism in selected Mediterranean countries (Croatia, Slovenia, Greece, Italy and Turkey). The purpose of our research is to investigate the main obstacles to greater application of renewable energy sources (RES) as the basis for the sustainability of nautical tourism. The obtained results provide valuable information that can help companies and policy makers choose appropriate strategies to achieve the EU 2030 sustainability goals in this sector. Our survey among charter companies was conducted during 2018 on a sample of 51 respondents. We conclude that there is a serious lack of knowledge among nautical tourism respondents regarding the availability of financial instruments from EU funds intended for increasing energy efficiency and adoption of RES. Respondents were familiar with general measures to reduce energy costs but are not familiar with the measures and opportunities provided by available European funds. Our results confirm previous research indicating that significant savings in energy consumption can be achieved by using RES (especially photovoltaic (PV) modules) and that insufficient financial resources and lack of knowledge are the main obstacles to achieving higher adoption rates of RES and increasing energy efficiency in nautical tourism.
