Privacy and data protection concerns in the regulatory framework of Slovenian energy law
Zoran Dimović, 2023, izvirni znanstveni članek

Opis: The implementation of smart energy systems (SES) in the Slovenian energy sector has raised significant privacy and data protection concerns. The collection and processing of personal data from energy consumers, as well as cybersecurity threats, pose risks that must be addressed. The legal framework governing privacy and data protection in the energy field in Slovenia is based on the GDPR, ZOEE, ZVPot-1, ZVOP-2 and others, which impose significant obligations on entities processing personal data. To mitigate these risks, exact terminology must be used to implement privacy, data protection and also cybersecurity measures and ensure compliance with the legal framework.

Integrating social dimensions into future sustainable energy supply networks
Matevž Obrecht, Yigit Kazancoglu, Matjaž Denac, 2020, izvirni znanstveni članek

Opis: Environmental protection and sustainable development have become an inevitable trend in many areas, including the energy industry. The development of energy supply networks is strongly correlated with the economics of energy sources as well as ecological and socio-political issues. However, the energy supply network is often distant from the social perspective. This paper therefore combines examination of perceptions and awareness of general public (web-based questionnaire) and top energy experts (a Delphi survey) on the energy supply network and identifies their potential integration in energy supply decision making processes. The results showed that public should be better informed as well as integrated into designing energy supply network as the prosumers gain power and the energy suppliers will no longer dominate the market. Public actors are ready to shape sustainable energy supply and also willing to pay 5.8% more for a sustainable energy supply. The majority are prepared to invest in renewable energy supply network close to their place of residence. Another result is that the public is calling for a shift in priority towards more sustainable and socially friendlier energy supply rather than focusing mainly on the economic and technical perspectives.

Food Waste to Energy through Innovative Coupling of CHP and Heat Pump
Jan Drofenik, Danijela Urbancl, Darko Goričanec, Zdravko Kravanja, Zorka Novak-Pintarič, 2023, izvirni znanstveni članek

Opis: This paper presents the conceptual design of a technological solution for the efficient conversion of food waste into heat and power. The distribution and composition of food loss and waste at different stages of the food supply chain in Slovenia and their potential for biogas production were determined. It was found that more than 50% of food waste comes from households. Therefore, a small plant was designed to convert food waste into biogas, which was innovatively coupled with a combined heat and power (CHP) unit and a heat pump. This doubles the amount of heat generated compared to conventional cogeneration. Based on the capacity of a micro commercial CHP unit, 3330 households (about 8000 residents) would supply food waste. The heat generated could replace 5% of the natural gas used for domestic water heating. The payback period would be 7.2 years at a heat price of about 80 EUR/MWh, however, for municipalities with more than 40,000 inhabitants the payback period would be reduced to less than 3 years. The cost price of the heat generated by this system would be about 25 EUR/MWh, taking into account the government subsidy for the operation of the CHP unit.

Investigating Winter Temperatures in Sweden and Norway : Potential Relationships with Climatic Indices and Effects on Electrical Power and Energy Systems
Younes Mohammadi, Aleksey Palstev, Boštjan Polajžer, Seyed Mahdi Miraftabzadeh, Davood Khodadad, 2023, izvirni znanstveni članek

Opis: This paper presents a comprehensive study of winter temperatures in Norway and northern Sweden, covering a period of 50 to 70 years. The analysis utilizes Singular Spectrum Analysis (SSA) to investigate temperature trends at six selected locations. The results demonstrate an overall long-term rise in temperatures, which can be attributed to global warming. However, when investigating variations in highest, lowest, and average temperatures for December, January, and February, 50% of the cases exhibit a significant decrease in recent years, indicating colder winters, especially in December. The study also explores the variations in Atlantic Meridional Overturning Circulation (AMOC) variations as a crucial climate factor over the last 15 years, estimating a possible 20% decrease/slowdown within the first half of the 21st century. Subsequently, the study investigates potential similarities between winter AMOC and winter temperatures in the mid to high latitudes over the chosen locations. Additionally, the study examines another important climatic index, the North Atlantic Oscillation (NAO), and explores possible similarities between the winter NAO index and winter temperatures. The findings reveal a moderate observed lagged correlation for AMOC-smoothed temperatures, particularly in December, along the coastal areas of Norway. Conversely, a stronger lagged correlation is observed between the winter NAO index and temperatures in northwest Sweden and coastal areas of Norway. Thus, NAO may influence both AMOC and winter temperatures (NAO drives both AMOC and temperatures). Furthermore, the paper investigates the impact of colder winters, whether caused by AMOC, NAO, or other factors like winds or sea ice changes, on electrical power and energy systems, highlighting potential challenges such as reduced electricity generation, increased electricity consumption, and the vulnerability of power grids to winter storms. The study concludes by emphasizing the importance of enhancing the knowledge of electrical engineering researchers regarding important climate indices, AMOC and NAO, the possible associations between them and winter temperatures, and addressing the challenges posed by the likelihood of colder winters in power systems.

Role of tourism in promoting geothermal energy : public interest and motivation for geothermal energy tourism in Slovenia
Barbara Pavlakovič, Milica Rančić Demir, Nejc Pozvek, Maja Turnšek, 2021, izvirni znanstveni članek

Opis: From household geothermal heat pumps to industrial geothermal heating and electricity production, geothermal energy is one of the most promising future climate change mitigation areas. This paper aims to analyse the potential role that the tourism industry has in the promotion of geothermal energy. Although general knowledge and understanding of geothermal energy is often relatively low, geothermal energy tourism has the potential to encourage the public to use and learn about geothermal energy and its applications. The paper first provides a theoretical conceptualisation of geothermal energy tourism at the energy production level and energy usage level. Empirical results from an online survey amongst a sample of the Slovenian population show that there is a reasonably strong interest in geothermal energy tourism, correlating with the public image of geothermal energy. The study furthermore identified three main motivational factors for energy tourism: the first is "Knowledge," followed by "Having fun," with the lowest level on the motivational factor being "Self-recognition." The paper finally provides future recommendations on geothermal energy tourism as a tool for wider public acceptance but also knowledge on the potential risks of geothermal energy as a sustainable energy source.

Visiting nuclear reactors : safety and security aspects
Barbara Pavlakovič, 2022, izvirni znanstveni članek

Opis: Visiting nuclear reactors is a niche tourism offer within energy (industrial) tourism, which leads tourists through areas that are not primarily meant for them. Hence, safety and security issues are even more critical in this case. This study aims to highlight different aspects of safety and security issues in nuclear power plant tours and to present measures taken to address these concerns. In addition, we studied the connection between plant visits and the public image of nuclear energy. Information was gathered through participant observation (personal visits of factory tours) and an online survey. There, we identified safety and security nuclear power plant visit protocols and a positive correlation between the visit variable and the two variables of the public image of nuclear energy, which suggests energy (industrial) tourism as a suitable tool to enhance awareness and knowledge about nuclear energy.
