Opis:
There has been a big increase in production and investments in wind turbines and wind farms in last 20 years. New generation of wind turbines is more reliable than from 1980’s are, which necessary condition is energy production is to play an important role among renewable energy sources. Over the last 30 years, the size of wind turbines increased 7 times, as nominal power increased nearly 14 times. At present, turbines capable of producing over 10 MW of power are being developed. The main reason for continued growth of turbines sizes is to minimize the energy cost per kilowatt-hour. However, it is worth remembering that according to the „square-cube law”, there is a maximum size after the surpassing of witch the cost of ever-larger turbines would grow faster than financial gain from the increased size. In this article, authors present energy storage methods and devices for wind power plants and cost-effectiveness of the individual energy storage methods. Authors also present data about energy storage efficiency and groups of energy storage devices for wind power plants such as: compressed-air power stations + gas turbine (CAES), utilizing underground wells, pumped storage power plants, rechargeable batteries (lithium-ion, lead-acid, sodium sulphur, VRB, zinc-flow, zinc-air, zinc-air), flywheels, hydrogen production and storage systems, superconducting magnetic energy storage (SMES), electrostatic storage – electrolytic capacitors.

European Energy Security Strategy
Opis:
The aim of this article is to assess the implementation process of the EU energy security policy in Central and Eastern European (CEE) countries. In the EU, energy security remains a crucial issue for European Energy Strategy, the fundamental goals of which include the security of supply, sustainability and competitiveness. Security of supply should be considered the most important aspect in this context, because it is connected to deep interdependencies between markets and economies, often based on political or even geo-political considerations. This is currently particularly noticeable, among other things, in the relations between the EU and Russia, where – in the event of any potential energy supply disturbances – some CEE countries are considered to be the most exposed. By analysing matters referred to the security of energy supplies, the article aims to determine the scope of activities undertaken by selected CEE countries which are also EU Member States in order to achieve this goal. The paper stresses the significance of cooperation by CEE countries at regional level, and focuses on initiatives and projects meant to ensure the security of their energy supplies. The conclusions of the paper assess some of the success stories as well as failures experienced by CEE countries in the process of building their energy independence.
Le but de cet article est d'évaluer la mise en oeuvre de la politique de sécurité énergétique de l’Union européenne dans les pays de l’Europe centrale et orientale (PECO). Dans l'UE, la sécurité énergétique est un enjeu crucial pour la Stratégie énergétique européenne qui contient parmi ces objectifs fondamentaux la sécurité de l'approvisionnement, la durabilité et la compétitivité. La sécurité de l’approvisionnement doit être considérée comme l'aspect le plus important dans ce contexte, car elle est liée aux interdépendances profondes entre les marchés et les économies, souvent basées sur des considérations politiques ou même géo-politiques. Ceci est actuellement particulièrement visible, entre autres, dans les relations entre l'UE et la Russie, où - dans le cas de perturbations concernant l'approvisionnement en énergie - certains PECO sont considérés comme le plus exposés. En analysant les questions concernant la sécurité de l’approvisionnement énergétique, l'article vise à déterminer l’étendue des activités entreprises par certains PECO [qui sont aussi les États Membres de l’Union européenne] afin d’atteindre cet objectif. L’article souligne l'importance de la coopération des PECO au niveau régional et se focalise sur les initiatives et les projets visés à assurer la sécurité de l’approvisionnement énergétique de ces pays. Les conclusions de cet article évaluent des réussites, ainsi que les échecs des PECO, dans le processus de la construction de leur indépendance énergétique.

The objective of the Energy Union is to integrate 28 national energy markets, guarantee free movement of energy through the borders of the member states, implement new technologies, increase energy efficiency and renew transmission infrastructure. This project is advocated in response to the energy crisis of 2009, between Russia and Ukraine, as a result of which the gas transit to some of the EU countries was discontinued. This project, however, does not enjoy equal interest among all EU member states. This is the outcome of the national interests of some member states, which, for many years, have had good political and economic relations with the Russian Federation, particularly in the area of energy raw materials. Therefore, Maroš Šefčovič – the European Commissioner in charge of the Energy Union, organised an Energy Union Tour, i.e. a series of meetings in all the member states, taking place at the turn of 2015–2016, the objective of which was to show what the Energy Union could offer each of them. The structure of the paper was determined by the research procedure and the response to all the research questions, comprising: introduction, reflections on the security of the energy raw material supply and the projects of Energy Union and Energy Union Tour as well as the conclusions from the research and the summary.

Opis:
Liechtenstein is the fourth smallest country in Europe, which determines the low economic importance of this country on the international arena. Therefore, Liechtenstein is usually overlooked in the analysis of economic policies in various countries, including the energy sector. However, the analysis of such a small country brings a valuable complement to researches on potential and challenges with regard to the implementation of energy transformation policy especially taking into account the countries with poor capabilities. It should be emphasised that due to difficult geographical conditions and strong external influences, deepened analysis of the process of formulating energy policy in Liechtenstein should arouse the interest of those countries that suffer geographical disadvantages to strengthen their energy security.

Opis:
Subject and purpose of work: The aim of the study is to identify methodological problems, which may be encountered during the preparation of the energy balance of a territorial unit, along with indications of ways to solve them. Materials and methods: Problems were identified during the preparation of the energy balance for two selected rural communes and then they were investigated with reference to the literature on this subject. Results: Estimating the energy demand of a local government unit requires proper identification of the groups of energy consumers, divided into facilities owned or co-owned by communes and ones independent from commune authorities. The latter group is divided further, into households, businesses, farms. For each of the users different methods of obtaining data may be needed: a survey and analysis of statistical data, analysis of financial documents, evaluation of the buildings’ age. Generally, however, preparing an energy balance statement requires many simultaneous approaches, and the combination of multi-criterion analysis provides the most reliable picture of the problem. Conclusions: The scope of the data needed to compile an energy balance statement for local government units, depends on the purpose of the developed analysis. Methodological handbooks and training materials on this subject are helpful, but the developed methodologies may need to be modified and adapted to specific conditions.
Przedmiot i cel pracy: Celem pracy jest wskazanie problemów metodycznych, na jakie napotkać można podczas sporządzania bilansu energetycznego jednostki terytorialnej, wraz ze wskazaniami sposobów ich rozwiązania. Materiały i metody: Problemy zidentyfikowano podczas sporządzania bilansu energetycznego dwu wybranych gmin wiejskich, a następnie skonfrontowano z literaturą przedmiotu. Wyniki: Oszacowanie zapotrzebowania na energię w jednostce samorządu terytorialnego wymaga właściwego określenia grup odbiorców energii w podziale na obiekty będące własnością lub współwłasnością gminy oraz niezależne od władz gminy. Druga grupa dzieli się dalej, na gospodarstwa domowe, przedsiębiorstwa, gospodarstwa rolne. Dla każdej z grup odbiorców mogą być potrzebne odmienne metody pozyskania danych: badanie ankietowe, analiza danych statystycznych, analiza dokumentów finansowych, ocena wieku budynków. Najczęściej jednak sporządzenie bilansu energetycznego wymaga stosowania wielu podejść równocześnie, a połączenie wyników analizy wielokryterialnej daje najbardziej rzetelny obraz badanego problemu. Wnioski: Zakres danych, potrzebnych do sporządzenia bilansu energetycznego jednostki samorządu terytorialnego, zależy od celu opracowania analizy. Poradniki metodyczne i materiały szkoleniowe na ten temat są pomocne, jednak opracowane metodyki mogą wymagać modyfikacji i dostosowania do konkretnych warunków.

Opis:
Aim: In the context of climate change this paper explores the value of models for evaluating energy costs by considering energy accounting and externalities instead of capitalistic economics.   Research methods: We test the hypothesis that the conventional economic model of the energy market can lead to inappropriate choices, and that those choices may be environmentally damaging. We examine energy accounting (energy return on energy investment), embodied energy and the incorporation of external costs as more valuable economic models.   Findings: This paper reviews existing economic tools and examines modifications, which, when applied to energy provision or efficiency and conservation of energy applications, may give more accurate information about investment, return and environmental damage. Energy accounting of schemes should be a preliminary requirement for all proposed energy schemes. Externalities are less readily applied, but as the costs associated with renewable energy are becoming competitive in conventional economic terms, they are less valuable than energy accounting.   Value of the paper: The paper concludes that a preliminary assessment of a proposed energy scheme should be undertaken using energy accounting and external costs to determine the true energy value. These models could be used to select the best environmental option. Indeed “energy uneconomic” schemes, which cost more energy than they deliver, should be abandoned in order to avoid unnecessary environmental damage. After this process, legislation and fiscal measures such as taxes and incentives could be applied to satisfy social and political imperatives. Examples of energy accounting in insulation and consideration of external costs in a proposed strategy to replace fossil-fuelled electrical generation in Indonesia are included in the paper.   Limitations: We have not considered the serious question of finite fossil fuel resources and feel that this would be a profitable line of research.

There is currently no common or standardized procedure for certification of the energy performance of buildings, as each EU Member State takes into account the specificities of its own construction sector when implementing the provisions of Directive 2010/31/EU. This usually depends on two features: the purpose of the building and the climate. Therefore, the purpose of this paper is to evaluate the influence of the hydropower primary energy factor for assessing the energy performance of buildings. For this purpose, non-renewable primary energy factor values were analyzed regarding actual energy production and consumption data from 19 Lithuanian hydroelectric plants. The results of the studies show that the average value of the non-renewable primary energy factor of hydropower plants is 0.059.

Opis:
Research background: Stable and reliable access to a variety of energy carriers is undoubtedly a basis for the development of any economy. Therefore, the primary condition for the security of the state and its citizens is to ensure the essential minimum of energy on its territory. We can observe, however, an increasing dependence of the Polish energy sector on external sources. Purpose of the article: The aim of this paper is to examine and evaluate the economic aspects of the Polish energy security considering the fact of growing de-pendency on foreign supplies of energy carriers. Methods: In this paper we analyze the Polish energy security using several indicators: fuel/price efficiency ratio, energy intensity of the economy and Herfindahl-Hirschman rate of market concentration. For calculations we use statistical data provided by Energy Market Agency publications, including ?Energy Situation in Poland? covering the years of 2000? 2015. Findings & value added: On the one hand, the Polish energy security depends on its internal conditions and resources - in this context, the available resources of coal and lignite play an extremely positive role because they provide access to a reliable source of energy. On the other hand, Poland is becoming dependent on external commitments that restrict the free use of domestic resources, thus lowering the energy security of the country, speaking in particular of oil and natural gas resources. The analysis carried out in this paper will allow to evaluate the effectiveness of using various energy carriers with respect to their price, market structure and geopolitical conditions.

As a general rule, the basis of regulation is set out in the adopted strategy papers, indicating developmental desires within the energy market. The energy policies that are taken, which define the implementation measures, should guarantee the secu-rity of investment in the long term. The increase in energy efficiency generates significant financial savings while generating benefits for the environment, industry, transport or households. As part of monitoring the level of en-ergy efficiency, the ODYSSEE-MURE programme has developed the ODEX indicator. The aim of thestudy was to analyze the level of efficiency in Poland in general and with an indication of three main sectors, as well as the level of Polish energy savings in the years 2008-2018. The research showed that the increase in energy efficiency of the Polish economy in the period under consideration is systematically increasing. Overall, between 2008 and 2018, the average rate of energy efficiency improvement was 1. 7% per year. On the other hand, savings achieved in 2018 within the indicated sectors amounted to 0.10 Mtoe.

The state of the energy security of Ukraine was analyzed with the help of data collection, processing and analysis. Data was taken from State Statistics Service of Ukraine, Ministry of Energetics and Coal Industry of Ukraine, other sources, and analyzed with the help of tools of statistics and economic analysis. Ukraine, being a developing country and experiencing war, political and economic crisis, struggles for energy security support. The present state of energy availability and consumption in the country influences its sustainable development and political stability, and is a significant restraint in country's survival. Despite the fact that Ukraine has enough resources' deposits to provide itself with energy, it provides less than 50% of own demands and is dependent on Russia's resources. Production of energy in Ukraine is decreasing, but energy consumption remains high. Ukrainian industries are energy-wasteful and energy-inefficient; the country has the leading positions in energy intensity of GDP. The article shows the relation of energy sources and energy security of Ukraine to sustainable development, reveals the dependency of the Ukrainian energy security, and indicates its main threats and ways out.

A transition from generating electricity from conventional sources to generating it from renewables is one of drivers leading us towards a circular economy. Electricity is a specific product and regardless of where and how it is produced, it takes the same form. A novel aspect of the research is the examination of correlations and relationships between guarantees of origin. The research objective is to analyse the market for the guarantees of origin in the volatile price environment that we had late 2021 and early 2022. Therefore, we analysed demand for the guarantees in January 1, 2020 to June 30, 2022 and the correlation between the price of electricity and guarantees of origin. It was based on the secondary data analysis method and the use of Pearson’s correlation coefficient and a linear regression function. The authors of the study made a hypothesis that the trading volume would increase during the study period and that there would be a positive correlation between the price of energy and the guarantees of origin. A key finding of the study revealed a steady increase in the purchase of guarantees despite the rise in prices. The buying of the guarantees is not a top-down requirement, but rather a bottom-up action, which indicates growing social expectations towards enterprises to consume energy from renewable sources.

Energy security plays a key role in energy and economic policy. The importance of energy security has been highlighted by the energy and geopolitical crisis. The aim of this article is to present the crucial threats and challenges facing Polish National Power System, as well as to provide solutions to ensure Poland's energy security over the next 10 years. Article verify the hypothesis that security of electricity supply in Poland may be endangered in the coming years due to, among others, investment gap, coal power plants phase-out and undiversified energy mix. Therefore, it is a necessity to accelerate the investment processes in new generation capacity, especially in nuclear energy. Energy transition plans and energy policy need to be revised in light of the current energy and geopolitical crisis. Rapid growth of photovoltaics improves the energy security, mainly in the summer period, nevertheless, there is still insufficient development of investment in renewable energy sources, particularly in wind energy. In the Polish National Power System there are a lot of constraints such as investment gap, low capacity of transmission and distribution grids and high exposure to climate risk, thus it is necessary to take comprehensive investments to improve energy security in both the short and long term.

Opis:
Energy is an abstract notion that helps to understand the nature and contributes to the creation of the civilization. The energy notion has a huge meaning not only due to practical reason – it is essential for economy and philosophy too. It turns out that in Hellenic philosophy, and especially in its fundamental part, i.e., metaphysics, there is no place for the concepts and methods of reasoning developed by physics and chemistry. Philosophy assumes that most of the physical and chemical concepts are not known in nature in spe these are employed by science only as a kind of mental keys (qualitative occultea) for the description and understanding of the universe. The concept of energy is only one example of a notion accepted both by the philosophers (in its metaphysical sense) and physicians (in its descriptive role).

Opis:
  Aim: In the 21st century, energy security is one of the most important elements of contemporary politics and economy. The German turn in energy policy is the first attempt on a global scale to move away from nuclear energy to the use of renewable energy (RES -Renewable Energy Sources), albeit with a temporary increase in the use of conventional energy sources (in particular coal). The authors undertook to analyze the course of the German policy turn as well as new opportunities and threats to the stability of its energy system, notably electricity sector.   Design / Research methods: In order to analyze the course of the German turn in energy policy as comprehensively as possible, the authors recurred to various studies, often presenting divergent points of view on changes in the German energy industry in recent years. The research process was based on the analysis of the content of the materials subject to consideration.   Conclusions / findings: The analysis carried out shows that the efforts to increase the share of renewable energy will be continued in the near future, while limiting the role of traditional energy sources, with the exception of lignite. The policy will also directly lead to a continued importance of natural gas for the global economy. The changes taking place in the German energy balance to a certain extent limit the country’s energy security. This is due to the fact that supplies from wind and solar power plants that are to become dominant in the German energy system are of high volatility and thus constitute a significant threat. Progress in generating energy from renewable sources is not accompanied by similar progress in its storage, and without such storage capacity renewable energy sources will never be stable.   Originality / value of the article: The doctrinal assumptions of Energiewende (German energy transition) are fully consistent with the assumptions of the European climate and energy policy, which is also very important from the point of view of Poland. However, attention should be paid to the fact that too rigorous approach to its implementation may - still for a long time - threaten the economy and energy security of Germany and of other European Union states.   Implications: The conducted analysis unambiguously indicates the direction of the energy policy turn in Germany and in other EU states, as well as a change in the way the energy security system operates. The example of Germany, a highly industrialized country seeking to actively participate in the fulfillment of the commitments regarding the international mechanisms designed to combat the climate change, in particular by the transition of its energy sector towards a near zero emission economy, may provide model solutions which could potentially be adopted in other countries.

Opis:
Rapid development of distributed energy resources technologies, along with network constraints, plus few consumer-oriented business models, has led to a search for radically different power system configurations. This is the basis for exploring an energy market model which meets the requirements of the changing environment. This model could be referred to as a transactive energy model whose main focus is on trading energy by a peer-to-peer principle, where the power company is replaced with a fully trusted trading platform based on distributed ledger technologies, i.e. blockchain technology. The aim of this paper is to analyze energy sector solutions related to the use of blockchain technology. The emergence of these solutions indicates, on the one hand, the need for verification of the existing energy market model and, on the other hand, the need to modify the approach towards the changing environment. Blockchain technology not only means the use of cryptographic mechanisms to build trustworthy agreements without intermediary institutions between the unfamiliar users of transactions: it is also a new philosophy of life based on trust.

The European Union undertakes numerous activities to implement a common energy policy for all Member States. However, since the countries in question have different energy resources, geographical location and terrain, unifi cation of national policies at EU level is a particularly arduous and difficult process. This article focuses on the analysis of energy sectors in Austria, Germany, Poland and Sweden. These countries were chosen because they offer considerable diversity, having different energy resources, geographical location, climatic conditions, as well as a different genesis of shaping their energy policy over the years. The analysis showed that the energy sectors in Poland, Germany, Austria and Sweden operate completely differently and rely on different energy resources. In Sweden, electricity mainly comes from hydropower and nuclear energy, while energy from coal is not produced at all. In Austria, coal is also not extracted, and the production of electricity is based mainly on renewable sources, and above all on hydropower. Germany is one of the countries with the highest level of coal mining in the world, therefore electricity is obtained mainly from this source, but also from nuclear energy and increasingly from renewable sources, mainly wind, biofuel and solar energy. Poland is among the world’s leading producers of coal, and obtaining electricity from this source accounts for as much as 80% in Poland; the rest comes from renewable sources, mainly wind energy, then biofuels, hydro energy and natural gas.

The Colombian government introduced a capacity market in order to promote the diversification in the energy matrix and protect users from high prices derived from dry seasonal events. Unfortunately, the flaws in the scarcity price definition- a mechanism that activates the capacity market obligation and sets a cap price for the spot market- have led into a market failure. Specifically, some generation plants have been forced to be unavailable because their variable costs are significantly higher than the scarcity price. This paper presents a qualitative and quantitative analysis of the Colombian Electricity system, with a particular emphasis on the definition of the scarcity price. Results present lessons and recommendations for policy makers based on the experience of the Colombian Electricity Market, highlighting the need of a new definition of the scarcity price and a different focus on the energy planning scheme.

Many countries worldwide support green energy production on large scale mostly by solar or wind energy subsidizing manufacture and operation of such systems. During the last two decades, there has been significant increase in wind energy production globally. Statistics show continuously growing investments in the development and installation of wind turbines and farms. Currently, wind energy is the second most important source of renewable energy after water energy. By 2016 global cumulative installed wind capacity surpassed 432 k MW [GWEC]. In last several years, most dynamic growth in wind power generation investments was recorded in Asia. Europe, in comparison, has less impressive but steady growth in wind power plants through the years. In this article, authors present global demand on energy in comparison to efficiency of wind power plants in relation to the local and global location as well as to the scale of installed system. Authors also present statistical data concerning wind power plants development. General classification, using number of criteria (ex. power output, construction size, rotor axis orientation and other) of wind to electric power converting devices is presented. Various types of devices, which authors describe in this article, can perform conversion of wind blow energy to the electric energy using different yet similar methods.

The concept of building autonomous energy regions is a new, innovative proposal to build self-sufficient regions in terms of energy in highly developed countries. The idea behind the formation of autonomous energy regions is to ensure energy security and the use of local resources for the construction of the energy mix. Because of the role and importance of energy for the development of economies and societies, in order to ensure the competitiveness of the Polish economy, it becomes necessary to start working on the construction of innovative energy concepts. The aim of the article is to present the concept of the construction of autonomous energy regions and analyse of the possibility of forming such regions in Poland.
Koncepcja budowy autonomicznych regionów energetycznych (ARE) jest nową, innowacyjną propozycją budowy samowystarczalnych pod względem energetycznym regionów w państwach wysokorozwiniętych. Ideą powstawania ARE jest zapewnienie bezpieczeństwa energetycznego oraz wykorzystanie lokalnych zasobów dla budowy mixu energetycznego, który w sposób pełny wpisuje się w uwarunkowania społeczno‑gospodarcze rozwoju danego obszaru. Wdrażanie koncepcji zmienia strukturę społeczno‑gospodarczą i stwarza nowe szanse rozwoju społeczno‑gospodarczego przy zachowaniu zasad zrównoważonego rozwoju. Z uwagi na role i znaczenie energii dla rozwoju gospodarek i społeczeństw, w celu zapewnienia konkurencyjności polskiej gospodarce niezbędne staje się rozpoczęcie prac nad budową innowacyjnych koncepcji energetycznych, w tym budowy ARE. Celem publikacji jest zaprezentowanie koncepcji budowy ARE oraz analiza możliwości powstawania takich regionów w Polsce.

Opis:
When systems of simple geometry like pipes or regular channels are considered, the mechanical energy loss of the fluid flow can be expressed by local and longitudinal empirical energy loss coefficients. However, in the case of large spatially distributed objects, there are no simple approaches to this task. In practice, general recommendations addressing different types of objects are used, but they usually provide very coarse estimates of energy loss. In this work, a new methodology for determination of mechanical energy loss in steady flowis proposed. This methodology is based on the observation that the magnitude of the power of energy dissipation in turbulent flow can be determined using the averaged flow velocity and turbulent viscosity coefficient. To highlight this possibility, an analysis of the magnitudes of the power of the main and fluctuating components of turbulent flow is presented. The correctness of the method is verified using an example of laminar and turbulent flows in a circular pipe. The results obtained show clearly that the proposed methodology can be used for mechanical energy loss determination in flow objects. This methodology can be used as a basis for mechanical energy loss determination in different types of flow objects.

Improving the energy efficiency of large grinding mills is of great importance to reduce the energy cost of mineral processing. The ratio of SAG mill to ball mill’s energy consumption varies greatly among SABC operations. Thus far, very few research studies have been conducted to demonstrate how the SAG mill or ball mill responses to the change of circuit energy distribution in terms of comminution efficiency. The present study investigated the energy performance of an operating SABC circuit at variable circuit energy distributions. An energy benchmarking model was used to assess the comminution energy efficiency of SAG mill, ball mill, and overall circuit. It is found that the target SABC circuit achieves the highest overall energy efficiency when 37.6% of the total circuit energy is distributed to the SAG mill and 62.4% to the ball mill. The maximum energy efficiency of this SABC circuit is approximately 25% when compared to the minimum practical energy required to carry out an equivalent comminution duty. The study also showed that the ball mill is more sensitive to the variation in circuit energy distribution than the SAG mill.

Opis:
The main objective of the text is to present an analysis that points to the existence of special “energy cultures” in the European Union. The comparative analysis encompassing the results of previous research into “energy cultures” employs statistical methods, i.e. a cluster analysis (Ward’s clustering method and k-means clustering method). The main sections of the text address: (1) the concept and examples of “energy cultures”, (2) a methodology of analysis, (3) aselection of indexes characterising “energy cultures”, (4) an attempt at grouping the European Union member states with the aid of clustering, (5) conclusions. With a view to making the research problem more specific, the present text features the following questions: (1) Is the claim that the European Union manifests special ‘energy cultures’ legitimate?, (2) Did the decade of 2001-2011 witness changes in the field of the European Union ‘energy cultures’, as earlier recognised by the literature?

Opis:
Combustion engines drive motor vehicles, which are commonly used, and their efficiency does not exceed forty per cent. It is hard to accept such a waste of energy nowadays when there is less and less fossil fuel and the ecological norms are being tightened. That is why hybrid power transmission systems and systems for energy recuperation - especially kinetic, so far being lost – are becoming more popular. One of such solutions is a unit to recover energy from a driver's seat vibration in a motor vehicle. It allows changing the kinetic energy of the vibrating seat into the electric one. Such a unit is installed under the driver's seat and supports the gaseous shock absorber. The unit consists of two toothed bars, coupled by two pairs of gear wheels, which drive the alternating current generator rotor. The rotor is joined with a driving shaft by one-way centrifugal clutches. One bar drives the rotor while the seat moves down and the other - while the seat moves up. The rotor is equipped with permanent magnets, which, by rotation, induce the power in the stator's winding. The generated power goes through the voltage stabilizing and rectification systems (4.75-5.25 V) and charges four batteries connected to USB output. The obtained electric energy may be used to supply other electronic devices, e.g. mobile phones. The unit will be installed in a farm tractor. The research checking the unit's effectiveness will be carried out in the near future.

Opis:
One of the basic obligations of the State towards its citizens is ensure energy security, defined as a situation where the economy can cover both the current and predicted consumer demand for fuels and energy in a technologically and economically reasonable manner, while observing requirements of environmental protection. Undoubtedly, in the context of electrical power energy security is understood as the security of supply, i.e. the capability of the power system to ensure the security of operation of the power grid and to balance the supply of electricity with the demand for this type of energy. This primarily depends on the availability of power generation sources of sufficient capacity. To ensure the continuity and stability of electricity supply to all end consumers in Poland in the medium- and long-term perspective, the Polish Ministry of Energy commenced drafting regulations concerning the capacity market as of 2016. These efforts have been aimed at causing an incentive effect in order to encourage making investment and modernisation decisions and to discourage decommissioning of the existing generation sources which determine the security of operation of the National Power System.

Opis:
According to the Energy Performance of Buildings Directive (EPBD), all new buildings must be constructed using technologies that will ensure almost zero energy consumption by the building through renewable energy sources and an energy-efficient thermal envelope. To assess the possibilities of reconstructing an existing building following the requirements of the EPBD in Ukraine, we have presented possible ways to modernise an office in Kyiv using renewable energy sources (biomass, heat pump) at different levels of thermal protection. Based on dynamic modelling results in the DesignBuilder software environment, the technical, environmental and economic aspects of building modernisation using near-Zero Energy Buildings (nZEB) technologies have been investigated. In particular, the authors have analysed the possibilities of using different modes of heat pump operation to provide heat to a building of different levels of thermal protection in the GeoTSOL software environment. The results obtained can be used to assess the benefits of improving the energy efficiency of a building using different types of renewable energy sources.

Opis:
The paper presents technological solutions that make possible to develop supervision systems to control operation of low-power energy generation sources. Operation of currently used control systems depends on technical conditions, needs of the source operator, and the binding energy law. The mentioned conditions do not cover the whole technological potential offered by modern devices that compose the SCADA system. That is why the paper presents new standards of data exchange and equipment that can be applied to develop a supervision system that supplies the required information to both the operator of generation sources and the power system operator with Such a solution makes possible to optimize the source and system operation with the application of various decision criteria.

Opis:
One of the most important sector of the national economy is the energy sector. A number of changes in the sector depends on a number of factors, not only technical and economic, but also social and political. At present Polish energy sector faces serious challenges. High demand on final energy , inadequate level of manufacturing and industrial infrastructure, dependence on the external supply of natural gas and oil, climate protection commitments, give rise to the need to take decisive actions. To achieve the objectives of the proper functioning of the energy system an essential element of the process is continuous observation and prediction of changes in the system in different timeframes. The complexity of the problems of the fuel economy and energy causes computer models to be an essential tool for their analysis. No decision about the introduction of regulations in the field of energy and ecology can do without previous studies of the effects which can be therefore estimated by using models.

Opis:
The study deals with economic and logistical conditions for the obtaining and use of various energy sources in the world. The first part presents the importance of energy in periods of human activity on Earth, from the time of gathering and hunting to modern times. It was pointed out how energy sources evolved based on successive innovations and inventions during subsequent periods of human development. The article presents the importance of individual energy sources in the modern world, indicating their logistical susceptibility in the field of extraction, storage and distribution. The length of periods of availability of non-renewable energy resources having the attribute of depletion was indicated using the Raw Materials Availability Index (RMAI). An analysis was made of the locations of individual energy resource deposits, stating that only a few countries have over 80% of global reserves, which means that other countries and societies depend on raw material monopolists.

Opis:
This article presents problems associated with the development of competition on the Polish energy market in the context of tariffs and pricing. National standards are set against the background of European legislation and the activities of the Energy Regulatory Office. The thesis is that the tariffs concerning distribution should be approved by the President of this authority because it is a natural monopoly, something the authors demonstrate in the following part of the article. However, the tariffs concerning selling should be free from confirmation even for households because this is a typical market. The authors do not ignore legal analysis and practical issues.
Cet article présente les problèmes associés avec le développement de la concurrence dans le marché de l’énergie en Pologne, dans le contexte des tarifs et des prix. Les standards nationaux sont présentés dans le contexte de la législation européenne et des activités de l’autorité de régulation de l’énergie (ERA). La thèse est que les tarifs concernant la distribution devront être acceptées par le Président de l’ERA, parce que c’est un monopole naturel, ce qui sera expliqué par les auteurs dans la partie suivante de l’article, mais les tarifs concernant la vente devront être libre, même pour les ménages, parce que c’est un marché typique. Les auteurs n’ignorent pas l’analyse de la loi et les aspects pratiques.
