Decentralized Energy

Until recently, the prevailing idea was that for the functioning of the energy system it is necessary to be composed of large plants and for energy to move from the centre of production to cities and places of consumption. With the advent of decentralized energy production systems and new technologies for their use, the original model is changing more and more. EU Directive 2018/2001 on the promotion of the use of renewable energy sources (RES) designates “prosumers”, i.e. at the same time both producers and consumers of renewable energy, as well as RES communities, while EU Directive 2019/944 introduced the term “citizen energy communities”, i.e. civil energy communities, provided that this Directive, in addition to the distributive production of electricity from RES, also includes electricity from other sources. EU member states are obliged to adopt their own regulations regarding the implementation of the directives, and after that the appropriate incentive measures. The Energy Communities initiative offers citizens new opportunities in terms of active involvement in energy issues. As they are decentralized RES-based projects, they promote the practice of sustainable energy production and consumption, as well as energy storage and exchange within the community. Traditionally passive consumer becomes an energy “prosumer”, a co-owner of a RES plant and a member of the energy community. There are thousands of so-called RES cooperatives in Europe, which are the most common organizational form of energy communities and can play an important role in the process of decentralization of the energy system. The transition to decentralized energy production has many advantages, namely: the use of local energy sources, increased security of local energy supply, shorter transport distances and reduced losses in energy transmission, encouraging community development and creating local jobs. The purpose of this paper is to bring closer to the general public in Serbia the concept of energy communities, what they are and what their role is, with most of the work dealing with energy communities in the EU.

Nowadays, in the context of climate change, efficient energy management and increasing the share of renewable energy sources in the energy mix are helping to reduce greenhouse gases. In this research, we present the energy system and its management and the possibilities of its development through the example of an ecovillage. The basic goal of such a community is to be economically, socially, and ecologically sustainable, so the study of energy system of an ecovillage is especially justified. As the goal of this community is sustainability, potential technological and efficiency barriers to the use of renewable energy sources will also become visible. Our sample area is Visnyeszéplak ecovillage, where we examined the energy production and consumption habits and possibilities of the community with the help of interviews, literature, and map databases. By examining the spatial structure of the settlement, we examined the spatial structure of energy management. We formulated development proposals that can make the community’s energy management system more efficient.

Abstract Examining willingness-to-pay (WTP) for renewable energy sources (RES) as well as views on energy topics can enable policymakers to design effective measures for facilitating the transition from fossil fuels to a renewable-based energy system. The aim of this study was to investigate environmental students’ willingness-to-pay for renewables and their views on various energy topics. Results showed that respondents preferred renewable-based electricity production to conventional energy production while solar energy emerged as the most preferred renewable type. In addition, most respondents were willing to pay for renewable energy but would pay relatively low sums of money per month. Moreover, respondents were divided over whether new lignite plants should be constructed in Greece. Finally, social media and special websites were the most favored media of daily information.

It is well-known that, in the past decades, the burning of fossil fuels was identified as the major cause of climate change. Climate change mitigation is becoming a central concern of global society. Limiting global warming to below 2 °C above the temperature of the pre-industrial period is the key to preserving global ecosystems and providing a secure basis for human activities, as well as reducing excessive environmental change. The ambitions increased at an accelerated pace with a dramatic expansion of net zero-emission targets. Increasing pressure from citizens and society has forced countries to intensify their climate plans, while the private sector has bought a record amount of renewable energy. An energy system based on fossil fuels must be replaced by renewable energy with low carbon emissions with improved energy efficiency. That applies to all consumers of fossil energy: cities, villages, building sectors, industry, transport, agriculture, and forestry. The paper explores and presents the strategy of energy development of renewable energy sources in the world. The application of new technologies that have led to developing renewable energy sources is presented in detail: wind energy, solar energy, small hydropower plants, biomass, and their increase in the total share of energy production, i.e., reduced fossil fuel use in energy production. Investments in new technologies used in renewable energy sources have led to increases in employment worldwide. Analysis of the trend of increased energy production from RES (Renewable Energy Sources) with investment plans, the employment rate for each energy source, and the development of renewable energy sources in the coming period are provided.

Energy stability and security have become one of the most important issues in recent years on planet Earth. Nowadays, worldwide economic, industrial and social development is related to the energy and energy-system that provided great benefits to a society, but the society is paying a high price because of the production and emission of carbon dioxide and other greenhouse gases into the atmosphere. There are numerous climate changes, which pose a threat to each continent, disorder in agriculture, disorder in food production, floods and fires, as well as changes in the ecosystem. Energy stability and security have become one of the most important issues in recent years. Energy is essential for development of any country, notably when it comes to its industry and economy. Without adequate policy operations of the energy sector, it is not possible to achieve industrial or economic progress. Nevertheless, no matter how important energy is for the development, it is only a mechanism for achieving the ultimate goals – sustainable economy, clean environment, high standard of living, prosperity and health of the population. This paper elaborates on and outlines a strategy for energy development of renewable energy sources in the world, as well as in the European Union. It presents in great details the application of new technologies that have led to the development of renewable energy sources: wind-power, solar energy, small hydro power plants, biomass, and their increase in the overall participation of energy production and reduction of fossil fuels in energy production. Investing in new technologies which use renewable energy sources have led to the increase in employment in the world, so that about 6.5 million people in the world have been employed until today. This paper outlines the trend of increasing energy production from RES (renewable energy sources) by investing in any of the abovementioned energy sources, as well as employment for each energy source in the world and the EU-28. Also, the development of renewable energy sources in the future has been presented.

Renewable energy production needs serious attention in highly traditional, inefficient, and energy-dependent countries like Nepal. Moreover, the option of an effective renewable energy technology that is economically feasible and environmentally acceptable is a topic of interest due to the availability of various types of renewable energy sources in Nepal. Among other renewable energy sources like micro hydro, solar, biogas etc, very few studies had been conducted on wind energy sources in Nepal and those few studies also focuses mostly on large scale wind farming. So, this study analyzes the suitability of distributed wind energy production in Tila village of Jumla district in the western part of Nepal. Five-year (2015-2019) wind speed data were examined to obtain wind power density and energy density. Two-parameter Weibull probability density function was used to evaluate these two quantities. The annual Weibull parameters k and c of 1.73 and 4.21 m/s were obtained to calculate 43.79 W/m2 power density and 378.37 kWh/m2 energy density. This study also provides the economic evaluation of a 100 kW distributed wind energy system, and the technical and economic aspects of the proposed system are compared with the corresponding characteristics of the existing renewable energy systems, i.e., micro hydropower and solar power. The study shows that when there is not enough sunlight for the solar PV system and not enough water flow coupled with maintenance problems in the micro hydropower system, the distributed wind energy system may function as a substitute system.
