Streszczenie:

Greening the economy requires green innovations, and innovations require investments. Most countries of the world are still relying on conventional (fossil-based) sources of energy. The transition toward green or renewable energy sources is an effective and innovative way to meet ever-increasing demand as a result of the rising population. Another reason for innovations in the field of green energy is the need to mitigate climate change and avoid pollution, especially in developing countries. The monitored investments into renewable energy sources are usually public. Therefore, this paper aims to determine whether the selected countries of the world produced renewable energy efficiently, considering the investments made by public financial institutions and installed electricity capacity for renewable energy sources, for the period 2013–2017 (for a deeper analysis, the year 2017 was chosen). For this purpose, the Stochastic Frontier Analysis model in the logarithmic form of the Cobb-Douglas production function is used, which helps to judge the competitiveness of countries based on effectively transforming the inputs into outputs. Results suggest that the effect of the first variable “installed electricity capacity” on electricity generation was highly statistically significant, and the impact of the second variable “public investments” was characterized as statistically insignificant. The monitored countries were divided into 10 groups according to the different range of estimated output-oriented technical efficiency from 0.00 to 1.00. Most countries should increase the renewable electricity generation approximately by 40-49%, given the level of inputs (16 countries of 6th group with estimated output-oriented technical efficiency 0.51-0.60) for the year 2017.

Streszczenie:

Global economic growth is accompanied by increased energy demand, thus conventional fuels such as coal, oil and gas, which are the primary energy sources, are gradually being depleted. At the same time, the combustion of conventional fuel for energy production causes serious adverse effects on the environment and contributes to climate change due to the emitted greenhouse gases. For the above reasons, most of the developed and developing countries especially during the last decades, have introduced various incentives for the greater penetration of renewable energy sources (RES) in all sectors of the economy. Concerning the building sector, several measures have been adopted, including the promotion of energy efficiency and energy saving. A significant proportion of the building stock are the school buildings where students and teachers spend a significant proportion of their daily time. Teachers' attitudes and views, especially the school unit managers concerning the use of RES in schools, are important in the effort to rationalize and control energy use. This study was conducted through a structured questionnaire applied to a sample of 510 school managers in Greece's primary and secondary education. The school unit managerial role for the case of Greek schools is performed by the school principal who has both administrative and educational duties. Statistical analysis included the application of Friedman's test and hypothesis test on questions concerning school manager environmental perceptions and energy-saving habits. According to the results, Greek school managers have a high degree of environmental sensitivity, since 97.6 % agreed or strongly agreed that the main concern should focus on energy saving. Furthermore, 71% of the respondent reported to have good knowledge on solar energy, followed by 64% on wind energy while only 34% are knowledgeable on biomass. Almost all the respondents (99%) agreed that it is important to provide more RES-orientated education through the taught curricula. Concerning energy saving behaviour, around 90% reported that they switch off the lights when leaving the classroom and they close the windows when the air-condition is operating. Hypothesis tests revealed a relationship between the school managers' ecological beliefs, the energy saving habits in the school environment, and the recognition of the importance of environmental education. Conclusions highlighted the need to intensify environmental education programs in the school environment concerning RES in schools. This will lead to a higher level of environmental awareness of both teachers and students and therefore to a more dynamic behaviour towards the effort to “greenify” the school environment.

The development of technology combined with the surge in population has led to a new era of living that has increased energy demand. Fossil fuel has been the main energy source for so many years, but it is no longer sustainable with its depletion and negative consequences. A need has arisen for a replacement resource to replace the depleting fossil fuels using right now. This need is what pushes us towards renewable energy. An examination of renewable energy sources: their uses, potentials, and limitations, as well as their effects on the climate and human health, is presented in this work. As final recommendations, the paper outlines policies and strategies to address climate change and fully integrate renewables as a sustainable energy source.

The subject of the present research is the assessment of access of residents of Northern cities to energy produced from renewable energy sources (RES). The largest Arctic cities in Russia, Sweden, Norway, Finland, Denmark, the USA and Canada, located above 66 ° 33 ´ North latitude, are analysed. The importance of the study is due to the categorisation of access to RES as a fundamental good in the context of Sustainable Development Goals and fight against climate change. The work uses the index method, followed by ranking cities by the level of access to energy from RES. The following variables constitute the index: variety of operators, variety of types of energy sources, alternatives of energy sources, micro- and macro-generation support. It was found that residents of Kiruna and Tromsø have the best access to energy from renewable sources due to the support of initiatives at all levels, while Utqiagvik has the lowest indicator due to its isolation. Energy from renewable energy sources does not have a significant share in all of the cities under consideration; moreover, the market is often monopolised, which limits the choice and availability of various energy sources. Consequently, it is important to create suitable conditions for developing of RES on all levels, with the focus on micro level (as it makes ordinary people participate actively in the agenda, which is the key to support such remote areas with energy); otherwise it is unlikely to support the cities and territories of the region with energy from RES.

Streszczenie:

Energy demand has grown rapidly with increase of global population. Surge in energy consumption is mainly driven by both economic and technological advancement. The conventional fossil fuels sources (coal, oil, and natural gas) and nuclear energy are depleting in nature known as non-renewables. Burning of fossil fuels contribute significant amount of greenhouse gases emissions, which negatively impact the global ecosystem. Access to energy is essential for modern civilization, yet we must seek alternative energy sources to protect our planet by controlling the emissions. Capturing harmful Green House Gases (GHG) with the help of advanced technologies helps reduce the risk to some extent. However, alternative energy sources must be renewable and sustainable. Renewable energy resources vary by geographical location and include solar, wind, hydro, and bioenergy, among others. The most appealing primary benefits of renewable energy include its low environmental impact, consistent availability even in challenging weather conditions, and its effectiveness in reducing pollution. Additionally, renewable energy contributes to economic growth, fosters job creation, and enhances energy security. However, there are challenges associated with renewable energy storage, which scientists are actively working to address. In addition, public opposition for the installation of renewable energy infrastructure also create difficulties. Increasing public education and awareness regarding the advantages of renewable energy can assist increasing the acceptability, which can further help policymakers in making well-informed decisions. This paper provides a comprehensive overview of diverse renewable energy sources and their current advancements in development. This review further finds that effective government policies aimed at reducing carbon emissions, coupled with improved technology and storage solutions, the adoption of renewable energy will expand significantly in the coming years.

The urban energy model is based on imports from external sources. The continuous increase in energy demand due to population growth and development implies increasing resource requirements. The alternative is to use renewable energies that take advantage of urban resources. The diversity of typologies of cities in terms of resources, demands, architectural conditions, infrastructure, or density, makes a specific analysis necessary. This work identifies fourteen factors concerning the planning process that would allow choosing the most appropriate technology for a given city. Through consultation of experts, the existence of the resource is defined as the most prevalent factor, followed by economic conditions; On the other hand, it is detected that environmental aspects such as global warming, eutrophication, or acidification, are the least incidents when selecting technologies.

<abstract> <p>The growing demand for energy, driven by rapid economic development, necessitates higher electricity consumption. However, conventional energy systems relying on fossil fuels present environmental challenges, prompting a shift towards renewable energy sources. In Kosovo, coal-fired power plants dominate electricity production, highlighting the need for cleaner alternatives. Worldwide efforts are underway to increase the efficiency of photovoltaic systems using sustainable materials, essential for ecological and human health. Solar and wind energy are emerging as sustainable alternatives to traditional fossil fuels. However, global concerns about energy security and environmental sustainability are driving countries to prioritize renewable energy development.</p> <p>In Kosovo, the integration of renewable energy sources, such as wind and solar energy, is progressing rapidly. However, challenges such as voltage stability and power losses need to be addressed. Distributed generation offers a solution by increasing energy reliability and reducing greenhouse gas emissions. Further research is needed to assess the technical, economic, and environmental implications of integrating renewable resources into Kosovo's energy system, focusing on power quality, system reliability, and voltage stability. The research focused on the eastern region of the country, operating at the 110 kV substation level. Challenges in energy quality arise due to the lack of 400 kV supply and the continuous increase in energy consumption, especially in the Gjilan area. This paper investigated integrating renewable energy, especially wind and solar sources, into the medium- and long-term plans at the Gjilan 5 substation to enhance energy quality in the area. Successful integration requires detailed analysis of energy flows, considering the impact of photovoltaics (PVs) on distribution system operation and stability. To simulate and analyze the effects of renewables on the transmission system, voltage profile, and power losses, a case study was conducted using ETAP software. The simulation results present a comparison between scenarios before and after integrating renewable systems to improve energy quality in the identified area.</p> </abstract>

The article discusses the importance of marketing in the market of renewable energy sources. Alternative energy and its development significantly depend on the country and the climatic conditions of a particular area. In Russia, alternative energy, its development, lags behind world leaders. There are several reasons for this. The first reason is the large reserves of fuel and energy raw materials and their low cost. The second reason is the low utilization rate of the installed capacity of alternative energy. The third reason is that the weather conditions in Russia are nonhomogeneous and not very suitable for the development of alternative energy. A promising direction for the development of alternative energy is small alternative energy. Marketing is built on effective market segmentation, increasing end-user awareness and customer education efforts. The article also provides recommendations for improving the effectiveness of marketing, its special features, taking into account altruism, paternalism and moral satisfaction ofcustomers.

Streszczenie:

The use of fossil fuels has contributed to climate change and global warming, which has led to a growing need for renewable and ecologically friendly alternatives to these. It is accepted that renewable energy sources are the ideal option to substitute fossil fuels in the near future. Significant progress has been made to produce renewable energy sources with acceptable prices at a commercial scale, such as solar, wind, and biomass energies. This success has been due to technological advances that can use renewable energy sources effectively at lower prices. More work is needed to maximize the capacity of renewable energy sources with a focus on their dispatchability, where the function of storage is considered crucial. Furthermore, hybrid renewable energy systems are needed with good energy management to balance the various renewable energy sources’ production/consumption/storage. This work covers the progress done in the main renewable energy sources at a commercial scale, including solar, wind, biomass, and hybrid renewable energy sources. Moreover, energy management between the various renewable energy sources and storage systems is discussed. Finally, this work discusses the recent progress in green hydrogen production and fuel cells that could pave the way for commercial usage of renewable energy in a wide range of applications.

Alternative energy is a strategic future for humanity because of the inevitable rise in cost and depletion of natural resources and, in the long term, nuclear materials for nuclear power operations. Every study in renewable energy development is an approach to make better use of renewable energy sources. Many countries have set targets for increased renewable energy clustering. Western European countries occupy an honourable place.The EU case study examines actions to integrate renewables into the current energy system, ensuring that the share of renewables in electricity generation reaches 12% by 2022. Renewables could thus change the fuel and energy mix, both of individual countries and of the global community as a whole, in the coming years.

This article deals with use of global energy sources and their environmental impacts. The energy sources have been split into three categories: fossil fuels (oil-coal-natural gas), renewable sources, and nuclear sources. Oil and gas are expected to continue to be important sources of energy. New efficient and cost-effective small-scale renewable energy generation options are commercially available today. The share of renewable energy sources is expected to increase very significantly. Recently, environmental problems resulting from energy production, conversion, and utilization have caused increased public awareness in all sectors of the public, industry, and government in both developed and developing countries. The environmental impact of energy use can be seen in two ways: The utilization of limited natural resources and the stress caused by environmental pollution. To combat that environmental damage, exploring and exploiting the utilization of combustible renewables and waste would be a necessary measure for decreasing the environmental impact of energy use.

The public perception of renewable energy sources is generally positive, due to their role in air pollution and CO2 emission mitigation policies. However, there are local environmental detrimental effects, and empirical evidence is not consistent as to the support of local communities. In the present paper, we analyse the antecedents of public generic perceptions of renewables grounded on objective location-related factors. Personal location-related factors can originate in the involvement of individuals with renewable energy sources. Regional location-related factors concern the importance of the renewable energy source in the district of residence and in relation to other renewables. We implement a questionnaire on public perceptions of renewable energy sources by the general population in mainland Portugal and complement respondent-level responses with renewable energy district information. Regression analysis shows that these objective location-related factors, both personal and regional, help explain public perceptions of renewables and thus we find empirical support for the proposed approach. These results can inform and guide policymakers in tackling future social acceptance issues of renewable energy policies towards lower carbon emissions and less polluting energy production.

The Main objective of this project is to develop a power management system that will control the power flow and energy demand of an integrated renewable energy system with the focus on solar energy and wind energy. These storage systems are needed to provide high reliability and control systems are necessary for the stable and optimal operation of the whole system. The voltage and frequency of the line side converter are controlled with indirect vector control with droop characteristics. The setting of frequencies varies according to the battery energy level, which slows down when the battery is charged or discharged. The system can also work if the wind power source is not available. An Intelligent Power Management System (IPMS) is developed to handle various changes in power supply and power demand by managing erratic power and providing a suitable control algorithm for the whole system. In order to test various power supply and power demand using a power system. The performed simulations confirm the ability of the IPMS to satisfy the load at all times using solar and wind power (which are unsteady renewables), through the support of batteries.

The use of renewable energy sources offers opportunities for regional and local development. Thus, it can be appreciated that the use of renewable sources can stimulate the development of local communities. An advantage is also given by an increased security in terms of local energy supply, but also by a reduction in energy transport losses. Recently, there has been some interest in investing in the development of energy generation technologies and especially in renewable sources. For the period 1990-2020, a comparative situation of gross electricity production and electricity production capacities for renewables is presented. Pollution and climate change can affect both the production and consumption of electricity. There has been interest in using more and more diverse sources. Given the interest in reducing energy consumption in transport, important measures are needed to increase the energy efficiency of transport. In the article, an analysis is made of the share of renewable energy in the final gross energy consumption, for the period 2004-2020, with particularization for the transport sector.

Abstract The utilization of renewable energy sources has an increasing role in the EU’s climate and energy policy. There are several reasons for increasing the use of renewable energy. The motives are the reduction of imported dependence on fossil fuels, mitigation of the adverse environmental impact of the energy sector and boosting of industrial development. The study provides a comprehensive overview on the structure and utilization of energy production of the Visegrad countries, focusing on the dependence on energy imports. The purpose of the article is to analyze the gross inland energy consumption of the Visegrad countries and to examine the relationship between renewables and non-renewable energy sources. In the course of the analysis, we tried to find out which non-renewable energy carrier is replaced by the renewables.

Energy transition requires actions from different sectors and levels, mainly focused on achieving a low-carbon and high-renewable integration society. Among the different sectors, the transport sector is responsible for more than 20% of global greenhouse gas emissions, mostly emitted in cities. Therefore, initiatives and analysis focused on electric vehicles integration powered by renewables is currently a desirable solution to mitigate climate change and promote energy transition. Under this framework, this paper proposes a multi-indicator analysis for the estimation of CO2 emissions combining renewable integration targets, reduction emission targets and realistic renewable resource potentials. Four scenarios are identified and analyzed: (i) current situation with conventional vehicles, (ii) replacement of such conventional by electric vehicles without renewable integration, (iii) and (iv) integration of renewables to fulfill emission reduction targets for 2030 and 2050 respectively. The analysis is evaluated in the state of Maine (United States). From the results, a minimum renewable penetration of 39% and 82%, respectively, is needed to fulfill the emission reduction targets for 2030 and 2050 by considering 100% conventional vehicle replacement. Different combinations of available renewable resources can reduce emissions by more than 35%.

The world’s ever-increasing population, combined with economic and technological growth and a new, modern way of life, has led to high energy demand and consumption. Fossil fuels have been the main energy source for many years, but their use has many negative impacts on the environment. This has made the transition to renewable energy sources necessary in order to address climate change and meet the 1.5 °C goal. This paper is a review of the different types of renewables, their potentials and limitations, and their connection to climate change, economic growth, and human health. It also examines consumers’ willingness to pay for renewables in different countries, based on the existing literature. IEA (International Energy Agency) data are analyzed, concerning renewables’ current use, the evolution of their usage, and forecasts about their future usage. Finally, policies and strategies are recommended in order to address climate change and fully integrate renewables as a sustainable energy source.

Background: This study tested a theoretical model including key psychosocial factors that could be involved in the acceptance of different energy sources (gas, wind, and solar); Methods: Participants were 550 adult residents of the Canary Islands. Variables assessed were information and utility (normative motives), perceived risk and perceived benefits (gain motives), and negative and positive emotions (hedonic motives), with acceptance of each of the three energy sources as outcome variables; Results: It was found that renewable energies (wind and solar) had a higher degree of acceptance than non-renewable energy (gas). The proposed model satisfactorily explained the social acceptance of the three energy sources, although the psychosocial factors involved differed by energy source. The gain motives, mainly perceived benefits, were associated to a greater extent with gas energy, whereas normative motives, such as utility, and hedonic motives, such as positive emotions, had greater weight for renewables. Gender differences in gas energy were found. Information about renewable energy increased positive emotions and acceptance, whereas information about fossil fuel-based energy generated more negative emotions and perceived risk, decreasing acceptance; Conclusions: Utility, perceived benefits and positive emotions were involved on the acceptance of both renewables and non-renewables. The theoretical model tested seems to be useful for understanding the psychosocial functioning of the acceptance of the various energy sources as an essential aspect for the transition of non-renewable to renewable energies.
