Improve Energy Efficiency

The food industry is a large consumer of energy that depends on fossil fuels, the combustion of which releases large amounts of CO2. The paper examines the possibility of reducing the use of non – renewable energy sources through a detailed energy audit and consideration of measures to increase energy efficiency and renewable energy sources in the ice cream craft industry. The cost-effectiveness of the proposed measures is observed for two scenarios. The first scenario covers the current situation in Serbia, in which there are no carbon taxes, and the price of energy is relatively low compared to other countries in Europe. The second „German scenario“ implies carbon taxes in the amount of 55€/tCO2, which is expected to, with the same energy prices, significantly reduce the repayment period and affect the ranking of measures. The analysis is performed to consider how the carbon tax reflects on the motivation of craft producers to improve energy efficiency.

The Impact

Abstract The development of civilisation is linked inextricably with growing demand for electricity. Thus, the still-rapid increase in the level of utilisation of natural resources, including fossil fuels, leaves it more and more urgent that conventional energy technologies and the potential of the renewable energy sources be made subject to re-evaluation. It is estimated that last 200 years have seen use made of more than 50% of the available natural resources. Equally, if economic forecasts prove accurate, for at least several more decades, oil, natural gas and coal will go on being the basic primary energy sources. The alternative solution represented by nuclear energy remains a cause of considerable public concern, while the potential for use to be made of renewable energy sources is seen to be very much dependent on local environmental conditions. For this reason, it is necessary to emphasise the impact of research that focuses on the further sharpening-up of energy efficiency, as well as actions aimed at increasing society’s awareness of the relevant issues. The history of recent centuries has shown that rapid economic and social transformation followed on from the industrial and technological revolutions, which is to say revolutions made possible by the development of power-supply technologies. While the 19th century was “the age of steam” or of coal, and the 20th century the era of oil and gas, the question now concerns the name that will at some point come to be associated with the 21st century. In this paper, the subjects of discussion are primary energy consumption and energy resources, though three international projects on the global scale are also presented, i.e. ITER, Hydrates and DESERTEC. These projects demonstrate new scientific and technical possibilities, though it is unlikely that commercialisation would prove feasible before 2050. Research should thus be focused on raising energy efficiency. The development of high-efficiency technologies that reinforce energy security is presented, with it being assumed that these new high-efficiency technologies are capable of being applied globally in the near future.

The World

The increase in population and industrialization has increased the consumption of electricity. Currently, it is impossible to live without electricity. Indeed, it is necessary for the economic, social and industrial progress in all the countries of the world. This is why we are always asked to develop all types of energy to produce clean and safe to improve energy efficiency. Indeed, the use of new renewable energy sources helps to mitigate greenhouse gas emissions and dependence on centralized energy sickles. The difficulties of renewable energy-based power systems lie in their production, which is not controllable and may not meet the increase in energy demand.

With the industrialization of the world, energy resources need management more than anything else. Because today we live in an energy-dependent world, we need energy to generate heat and cold, to create light, to start car engines, to run factory gears, to harvest crops, and so on. Therefore, the present study aimed to investigate the need for efficiency of energy sources management in sustainable architecture was conducted. In this research, a descriptive-analytical method has been used to look at the concept of energy resources management and sustainable development and their relationship, to study renewable energy sources in Iran and to propose proposed solutions in this regard. The results show that energy management requires the presentation of policies by managers of a country and also requires public education at the community level. Achieving sustainable development also requires access to sustainable energy sources that non-renewable energy and fossil fuels are not suitable sources in this regard due to unsustainability, but renewable energy will remain for future generations if used, unlike fossil fuels. They will not lead to pollution and global warming. Undoubtedly, by replacing renewable energies with non-renewable energies, the steps taken towards sustainable development will become stronger. In addition to these issues, the epidemic and the increase in the number of victims and victims of the Covid-19 virus, which led to the closure of oil fields, refineries, mines, etc., was another blow to the managers and officials of countries to find out more than ever the only solution to these problems is referring to renewable energy.

Global Power

National and international energy policies have very important role in regional and global power equilibrium and its importance is increasing. In this respect, diversification of energy resources and their transportations routes, efficient use of local resources and the use of existing energy resources with various technological and strategic practices in the most efficient way possible are necessary in order to improve energy security and reduce dependence on foreign energy sources. Energy efficiency and renewable energy sources stand out as an important issues especially regarding energy supply security, reducing foreign energy dependency, economic development, maintaining the balance between environment and sustainability as well as making important gains in all these issues. Thus, Improving energy efficiency saves money, reduces carbon emissions and decreases country’s dependence on foreign energy supplies. Energy security—the uninterrupted availability of energy sources at an affordable price—can also profit from improved energy efficiency by decreasing the reliance on imported fossil fuels. Possible improvements in energy efficiency are examined in six main categories: (1) buildings, (2) industry, (3) transportation, (4) electricity generation and distribution, (5) appliances and equipment, and (6) lighting

This paper presents a novel, scalable, and modular multiport power electronic topology for the integration of multiple resources. This converter is not only scalable in terms of the integration of multiple renewable energy resources (RES) and storage devices (SDs) but is also scalable in terms of output ports. Multiple dc outputs of a converter are designed to serve as input to the stacking modules (SMs) of the modular multilevel converter (MMC). The proposed multiport converter is bidirectional in nature and superior in terms of functionality in a way that a modular universal converter is responsible for the integration of multiple RES/SDs and regulates multiple dc output ports for SMs of MMC. All input ports can be easily integrated (and controlled), and output ports also can be controlled independently in response to any load variations. An isolated active half-bridge converter with multiple secondaries acts as a central hub for power processing with multiple renewable energy resources that are integrated at the primary side. To verify the proposed converter, a detailed design of the converter-based system is presented along with the proposed control algorithm for managing power on the individual component level. Additionally, different modes of power management (emulating the availability/variability of renewable energy sources (RES)) are exhibited and analyzed here. Finally, detailed simulation results are presented in detail for the validation of the proposed concepts and design process.

The Europe 2020 Strategy was proposed with a long-term vision to ensure prosperity, development, and competitiveness for the member countries. This strategy is divided into three main areas named “growth”. One of these is sustainable growth. This is an area of sustainability, where the partial targets are referred to as the “20-20-20 approach”, and includes a reduction of greenhouse gas emissions, an increase in energy efficiency, and the sharing of renewable energy sources. However, questions arise, including: How do member states meet these targets? Which countries are leaders in this area? According to these stated questions, the aim of this article is to assess how EU countries are meeting the set targets for sustainable growth resulting from the Europe 2020 strategy and to identify the countries with the best results in this area. We looked for answers to these questions in the analysis of sustainable indicators, which were transformed into a synthetic measure for comparability of the resulting values. Finally, we identified the Baltic states, Nordic countries (European Union members), Romania, and Croatia as the best countries in fulfilling the sustainable growth aims. As sustainable development and resource efficiency are crucial areas for the future, it is important to consider these issues.
