The European Union has taken the course to become climate neutral by 2050. To reach that target significant changes in all sectors are necessary, resulting in increasing regulatory pressure on energy producers, consumers and other sectors. Increasing legal requirements was also one of the reasons why the city of Daugavpils (population of 82 000) to...

... about energy consumption on a regular basis, and in most of the cases data were not compiled even annually. The flow of energy data and financial resources in 2015 are shown in Fig. 4. After the EnMS was introduced, new data information flow was introduced so the information would be gathered centrally, and analysed on a regular basis (see Fig. 5). Based on the results, feedback to buildings should be provided and reports to SECAP working group delivered to feed the decision making. The administrative body that is responsible for SECAP and EnMS implementation is the Department of Development of the Daugavpils City Council. Approximately 218 persons are involved in EnMS to some ...

... In many cases, municipalities are encouraged to develop sustainable energy and climate action plans, but eventually, they do not know how to properly work with data and make evidence-based decisions [31]. To fulfill the obligatory structure of the SECAP given by the CoM is not easy, especially for medium-and small-sized cities [32]. ...
Directive 2018/844/EU on energy efficiency claims that almost 80% of the final energy consumption in the EU is used within the buildings. The subsequent Directive (EU) 2023/1791 introduced in 2023 expected 68% of the world population to live in urban areas. Both directives enhanced the role of energy management (EM) applied to the city buildings. This paper introduces the development of energy management in Czech municipalities between the years 2009 and 2023. The main goal of this article is to present selected results of the unique national survey focused on the energy management in Czech municipalities conducted in 2023 and compare it with results of national surveys implemented in 2009 and 2018. The main method is the comparing of two surveys conducted among the municipal representatives or energy managers in the past with the new survey conducted in 2023. The results show that EM became a notably more important issue for most Czech municipalities. The number of cities collecting data on energy consumption grew by 288% and the number of city energy managers increased by 57%. On the other hand, the used potential of energy savings triggered by establishing EM was insufficient and only 4% of the respondents claimed high and exactly measured savings because of EM. This article should be applied to the stress power of municipal EM in performing energy efficiency and RES projects and encouraging the government to support municipal energy managers in their complex role.

The main goal of this article is to present selected results of the unique national survey focused on the energy management in Czech municipalities conducted in 2023 and compare it with results of national surveys implemented in 2009 and 2018. The main method is the evaluation of deep survey conducted among the municipal representatives or energy managers in the past with the new survey conducted in 2023. The results show that EM became notably more important issue for the most Czech municipalities. The number of cities implementing EM significantly grew and the number of city energy managers increased too. On the other hand, the used potential of energy savings triggered by establishing EM is insufficient.

... Around 15% of the total energy consumption is due to refrigeration, ice making, air conditioning, and aeration systems [8]. The design of a methodological structure that leads to the saving of energy resources and reduces adverse environmental effects contributes positively to the development of the country, the formation of solid commercial links between companies, and the production of services and products of optimal quality [9]. ...
Food and Agriculture Organization (FAO) estimates an average of 140, 300, and 589 kWh of electrical energy consumed to process fishmeal, fish, and shrimp, respectively, without adding the costs associated with freezing the finished product. Current research focuses on implementing an Energy Management System (EnMS) in a seafood processing plant that supports energy savings at low cost. This article presents, as a contribution from the qualitative point of view, the non-need for external financing to implement the EnMS under the ISO 50001 standard and the identification of the Energy Performance Indicators (EnPIs) of the case study plant. The energy awareness of the workers is evident when analyzing the results of the surveys carried out before and after the implementation of the EnMS. As part of the research, an Automated Reporting System (ARS) is developed; the performance enables energy information to be concentrated in a single file under a standard format approved by the energy commission and sent systematically. From a quantitative point of view, there is a 13.2% reduction in the total electricity consumption of the plant and a decrease in the cost of electricity needed per ton produced, from 9.40 USD to 7.30 USD. The emission of greenhouse gases into the atmosphere due to electricity consumption decreases by 13.78%.
... The ISO 50001 standard for EnMS considers the achievements in energy management by industries as well as the country. The major impact on the business formations is the good-quality material, the constant flow of energy and also their mutual interactions in a manner that provides useful information to design a methodological structure with as high-quality resource savings as possible and fewer negative environmental effects [14,15]. ...
... However, similar to the carbon leakage phenomenon [98], an increase in the price of energy may lead to a relocation of activities to areas with lower energy prices [99]. In addition to the above measures, education and information programs, such as energy labelling [100], energy audits [101], energy management systems [102] and training and certification of energy managers, are being implemented in order to raise awareness [103]. ...
Through a systematic literature review and a holistic perspective, the study proposes a conceptual transdisciplinary framework to overcome energy efficiency barriers during the shipbuilding phase. The process of the proposed transdisciplinary framework consists of five steps of "goal formation", "system analyzing", "scenario construction", "multi-criteria decision making as-sessment" and "strategy building" to identify and rank the energy efficiency barriers during ship construction based on decision makers' priorities. The framework categorizes the barriers into five disciplines-operations, policies and regulations, technology and innovation, the human elements, and economics-and the framework is applied to an Iranian shipyard. The results show that the economic barriers have the greatest impact, while the human barriers have the least impact on the shipyard's energy performance. Due to the generalized structure of the framework, it categorizes not only energy efficiency barriers according to the importance and priorities of stakeholders in the shipbuilding industry, but can also be applied to other phases of the ship life cycle and even to other industries. By applying the framework, decision-makers can make rational and optimal decisions to be able to invest in energy efficiency measures based on their priorities.
... To date, EnMS based on this standard have mostly been implemented by companies. The number of municipalities in the European Union holding an ISO 50001 certificate is very low [5]. Based on data from the ISO survey 2019, there were 18,227 valid ISO 50001 certificates at the end of 2019 [6], of which only 34 were from the public administration sector. ...
... They also emphasized that assistance by consultants experienced with energy management systems can be of critical importance. Jekabsone et al. [5] reviewed the case study of the Latvian city of Daugavpils, where the authors supported the municipality in implementing an energy management system. The implemented energy management system was certified according to ISO 50001 in 2016. ...
... More than 100 public buildings, public street lighting, and the public transportation system are within the boundaries of the EnMS. In the case study by Jekabsone et al. [5], the EnMS helped identify public buildings with high specific and absolute energy consumption and prioritize energy efficiency measures, including renovation. In 2019, the heat consumption of public buildings was 12% lower and electricity consumption 8% lower than in 2016. ...
Managing energy use by municipalities should be an important part of local energy and climate policy. The ISO 50001 standard constitutes an internationally recognized catalogue of requirements for systematic energy management. Currently, this standard is mostly implemented by companies. Our study presents an approach where consultants supported 28 European municipalities in establishing energy management systems. A majority (71%) of these municipalities had achieved ISO 50001 certification by the end of our study. We also conducted two surveys to learn more about motivations and challenges when it comes to establishing municipal energy management systems. We found that organizational challenges and resource constraints were the most important topics in this regard. Based on the experiences in our study we present lessons learned regarding supporting municipalities in establishing energy management systems.
A viable remedy for lowering hazardous greenhouse gas emissions and carbon footprint is through the adoption of electric vehicles (EVs). Electric vehicles minimize fossil fuel reliance and ozone-damaging compounds by supporting large-scale renewable deployment. However, EV modeling and manufacturing are continuing to change despite extensive study on the qualities and characteristics that are evaluated from time to time. This is due to restrictions on EV adoption and their charging infrastructure. The present study addresses the numerous modeling approaches and optimization strategies used in studies of EV, hybrid, plug-in hybrid, battery, and fuel cell EV penetration and adoption rates in the market. The study is unique for a developing country like India in that it addresses crucial challenges in adoption and the lack of charging facilities for EV consumers. In addition, when renewable energy sources are unavailable, the development and deployment of the vehicle-to-grid concept is an innovative strategy to provide auxiliary supply to the grid. It is concluded that considering the unique features of EVs is vital to their adoption and mobility.
