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.

The study evaluates changes in the production and consumption of energy from renewable sources in the conditions of the development of circular bioeconomy. The general structure of the energy market was presented and then the importance of bioenergy, other renewable energy sources and energy from waste in the EU energy system was analyzed. Research shows that the current EU policy has brought a significant increase in the use of renewable energy sources in the structure of energy production and consumption in the EU. It was also found that the use of waste in energy production in the EU is low and significantly diversified in individual member states.

The purpose of this article is to present the changes in the structure of production and consumption of energy from renewable energy sources in Poland and in the European Union. Renewable energy sources account for only about 16% of world energy production. This situation, however, from year to year changes. Prym in the use of energy from renewable sources leads the European Union, which has set itself an ambitious target that by 2020, 20% of the energy extracted from the green renewable energy sources.

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.

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.

This paper built up GM(1,1) models for energy production and consumption in China. Then predicted and analyzed total amount of energy production and consumption in China as well as the structure of energy. The study showed that GM(1,1) model can simulate and predict the trend of the total amount of energy consumption and the structure well. In the future, the structure of energy consumption will be optimized. The proportion of coal and oil will decrease and the proportion of gas and renewable energy sources will increase in order to fill the gap.

Production And Consumption

To lower the production of greenhouse gases while covering energy needs, it is necessary to exploit renewable energies in the urban environment and manage energy production and consumption as well. In this work, we interested in the study of a house using renewable energy sources such as photovoltaic (PV) panels, thermal panels and wind turbines (WT). The energy consumption happens through electrical charges like the refrigerator, the heat pump, the lighting... The main objective of this work is to change the operating time of secondary loads and to propose an energy management algorithm. Firstly, we will model the consumption of electrical charges and move the operation of secondary charges to moderate the consumed energy. Finally, we suggested an algorithm to manage and optimize energy production and consumption. The results show that the displacement of secondary loads reduces over 8.5% of the energy bill and the suggested algorithm optimizes the operation of the energy production equipment while covering the energy needs of the inhabitants.
