As efforts are made worldwide to meet the growing energy needs of the population in a more sustainable way, harnessing weather-dependent renewable energy sources is becoming more and more important. One of the available technologies is photovoltaic energy production. In the last decade, there has been a growing need among households, institutions, and businesses to reduce the use of fossil-fuel-based electricity from the public grid. In order to meet their electricity demand in Hungary, investors prefer using household-sized photovoltaic power plant (HMKE) systems. The novelty of this study is that it examines the number and total power of photovoltaic HMKEs at the district level in the service areas of different electricity distributors, taking into account the social, economic, infrastructural, and welfare dimensions of these districts as well. The study seeks to uncover whether there is a correlation between the number and total power of these types of power plants and the indicators of the districts, and if so, how strong these relationships are. The examination of the relationships also involved, in addition to correlations by pairs, the relationships of the ranking of the districts according to the complex indicators created from the district indicators and the ranking of the districts based on the number and power of photovoltaic HMKEs per 1000 members of the population. By exploring correlations, the paper seeks to establish a regression model for the number of photovoltaic HMKEs and the territorial (district) indicators.

The Relationship

In the global transformation of energy systems, solar energy plays a prominent role, since the energy from our star is a limitless and clean resource, which is available practically almost everywhere. In spite of the immense advancements of photovoltaic systems, which utilize this source of energy, no in-depth research has been carried out regarding the present Hungarian status of the small-scale photovoltaic power plants, the most common type of solar power plant in Hungary. The novelty of this study is that it examines the number and power of these small-scale power plants at the settlement level within the service areas of the various distribution companies, by also considering the economic and infrastructural dimensions of the settlements. The paper seeks answers to the questions whether there are any significant relationships between the number and the power of power plants of this type and the indicators of the settlements, and if so, how strong they are. Besides pairwise correlations, the study also involved the analysis of the relationship between the ranking of the settlements based on the settlements’ complex indicators that were created from the settlements’ indicators and the ranking of the settlements according to the number and power of household-sized photovoltaic power plants per 1000 people. In the course of exploring the relationships, a regression model was also devised concerning the number of household-sized photovoltaic power plants and the settlement indicators.

Abstract Lack of investment in the electricity sector has created a huge bottleneck in the continuous flow of energy in the market, and this will create many problems for the sustainable growth and development of modern society. The main reason for this lack of investment is the investment risk in the electricity sector. One way to reduce portfolio risk is to diversify it. This study applies the concept of portfolio optimization to demonstrate the potential for greater use of renewable energy, which reduces the risk of investing in the electricity sector. Besides, it shows that investing in renewable energies can offset the risk associated with the total input costs. These costs stem from the volatility of associated prices, including fossil fuel, capital costs, maintenance, operation and environmental costs. This case study shows that Iran can theoretically supply ~33% of its electricity demand from renewable energy sources compared to its current 15% share. This case study confirms this finding and predicts that Iran, while reducing the risk of investing in electricity supply, can achieve a renewable energy supply of ~9% with an average increase in supply costs. Sensitivity analysis further shows that with a 10% change in input cost factors, the percentage of renewable energy supply is only partially affected, but basket costs change according to the scenario of 5–32%. Finally, suggestions are made that minimize risk rather than cost, which will bring about an increase in renewable energy supply.

The Republic

In this paper we analyze the impact of the renewable energy sources on the overall electric power system of the Republic of Macedonia. Specifically, the effect of the photovoltaic power plants is examined. For this purpose we developed an electricity production optimization model, based on standard network flow model. The renewable energy sources are included in the model of Macedonia based on hourly meteorological data. Electricity producers that exist in 2012 are included in the base scenario. Two more characteristic years are analyzed, i.e. 2015 and 2020. The electricity producers planned to be constructed in these two years (which include the renewable energy sources) are also included. The results show that the renewable energy sources introduce imbalance in the system when the minimum electricity production is higher than the electricity required by the consumers. But, in these critical situations the production from photovoltaic energy sources is zero, which means that they produce electricity during the peak load, and do not produce when the consumption is at minimum.

In recent years, undocumented youth have come out of the shadows to claim their rights in the United States. By sharing their stories, these youth gained a voice in the public debate. This article integrates insights from the literature on narratives and emotions to study how story-telling is employed within the undocumented youth movement in Chicago. I argue that undocumented youth strategically use storytelling for diverging purposes depending on the context, type of interaction, and audience involved. Based on ethnographic research, I show that storytelling allows them to incorporate new members, mobilize constituencies, and legitimize grievances. In each of these contexts, emotions play a key role in structuring the social transaction between storyteller and audience. Storytelling is thus a community-building, mobilizing, and claims-making practice in social movements. At a broader level, this case study demonstrates the power of storytelling as a political tool for marginalized populations.

This article explores how Korean bloggers, in contestation, participate in the social structure of communication and potentially transform it through their vernacular practices of decoding and recoding in the blogosphere. As a neo-liberal regime has been established, citizens practise discursive politics in a seemingly democratic and technologically advanced society that is actually a coercive-controlled communication system. Through the analysis of news blogs on the Cheonan disaster, it is suggested that a majority of bloggers are seen to utilise news media stories to gain leverage for their points of view or to provide counter-arguments against the dominant frames generated by the established news media. The critical reframing of the digital network in Korean society allows a reflexive reading of the Korean digital wave, which should be contextualised within generation politics, economic polarisation and ideological contestation. In order to avoid a nationalistic celebration of the IT power of the country, citizens' digital media practices are analysed as contributions to the democratisation of the public sphere and the enhancement of social openness and participation in the digitised arena of discursive politics.

PurposeThe paper aims to reach a better understanding of accountability and social reporting in the Italian justice system, by examining the state of the art of both literature and practice. The case study highlights the critical elements in drawing up the social report of one of the most important Prosecutor Offices in Italy.Design/methodology/approachThe case study analyzes the activities of the actors involved in the report building process by detailing all the steps involved in a research diary, in order to examine such process from the inside, thus reversing its perspective.FindingsThe study shows that both the lack of guidelines for judicial administrations and a consolidated trend of transforming administrative facts into documents useful to stakeholders slow down the evolution of practices, which are stuck in a perpetual trial stage.Research limitations/implicationsThe limitations are mainly related to the adoption of a single case study, which does not include any comparison with other reporting experiences in the justice sector.Originality/valueThis paper adds evidence to the theoretical debate on social reporting in the justice sector which has so far received the attention of a limited number of scholars. Furthermore, unlike other studies focusing exclusively on the final report while overlooking the process that turns input into output, this research deals with the core of the social reporting process and practices in their development, capturing their most intimate and controversial aspects from the inside.
