В данной работе приведены некоторые данные оценочных расчетов энергетического потенциала рек Казахстана и кратко изложено состояние вопроса малой энергетики Казахстана. Рассмотрены современное использование энергетических ресурсов и перспективы их дальнейшего освоения в различных странах, в том числе в Казахстане, определены основные трудности освоения и развития малой гидроэнергетики и состояние данного вопроса в Казахстане. Приведённые факты, анализ перспективного электропотребления позволяет сделать вывод, что применение дизельных станций потребует дополнительного завоза десятков тыс.т. жидкого топлива и это усложняет топливоснабжение этих станций и несомненно является тормозом дальнейшего подъема экономики Республики. This paper presents some data of estimated calculations of the energy potential of the rivers of Kazakhstan and briefly describes the state of the issue of small-scale energy in Kazakhstan. The current use of energy resources and the prospects for their further development in various countries, including Kazakhstan, are considered, the main difficulties of the development and development of small hydropower and the state of this issue in Kazakhstan are identified. The given facts, the analysis of prospective power consumption allows us to conclude that the use of diesel stations will require additional import of tens of thousands of tons. liquid fuel and this complicates the fuel supply to these stations and is undoubtedly a brake on the further economic recovery of the Republic.

AbstractHydropower plants in Poland currently use only 19% of the river’s energy potential. Development of hydropower is limited by environmental regulations as well as by economic grounds. From the environmental point of view, it is desirable to build small hydropower plants integrated into the local landscape. This paper presents results of the research aimed at estimating the amount of energy that could be produced in the case of small hydroelectric power plants on weirs existing on the Tyśmienica River. There is also a legal framework that should be adapted at hydropower development. It was calculated that the technical capacity of the small hydropower plants that could be built on 4 existing weirs, is 0.131 MW. These power plants could produce 786 MWh of electricity per year. The economic efficiency of this production is currently difficult to assess, because a new support system for renewable energy sources is currently being implemented, which will be a decisive factor for entrepreneurs. It should be borne in mind that potential investments will be made in protected areas within the Natura 2000 network, which may limit their constructing or impose the obligation to assess their impact on selected environmental elements. Location within the protective area does not eliminate such investments, especially when solutions with the least possible environmental impact are used.

This chapter presents in a consolidated manner the step-by-step methodology to estimate the electrical energy potential of industrial wood residues considering the dependency of the efficiency of the power plants with their size. A function of the overall efficiency with power was obtained from a best curve fit of real data both taken from the literature and from Brazilian biomass-fired power plants. The methodology was applied to the determination of the electrical energy potential of wood industry residues in the State of Pará (data collected in 2004). Two cases were analyzed: one where a constant electrical efficiency of 25% was considered (independently of the amount of residues generated) and another where the proposed function of efficiency with power was used. Results show that in the State of Pará, the existent 675 sawmills generated 2.95 × 106 t in dry basis. When the dependency of efficiency with plant size is not considered, the electrical energy potential and average installed power (3140.4 GWh and 2 MWe) are overestimated in comparison to the herein proposed methodology (1868.8 GWh and 1 MWe). The present methodology, considering the efficiency as a function of the power, results in an average efficiency of 12.3% (lower than 25%).

Community energy (CE) and grassroots innovations have been widely studied in recent years, especially in the UK, Germany, and the Netherlands, but very little focus has been placed on Sweden. This paper describes and analyses the development and present state of several types of community energy initiatives in Sweden. The methodology uses interviews, document studies, analysis of previous studies, and website analysis. The results show that fewer initiatives have been taken in Sweden than in other countries, but that even with a rather ‘hostile’ institutional setting CE has emerged as a phenomenon. Wind cooperatives are the most common form of initiative, with solar photovoltaics cooperatives and eco-villages also prominent. The various types of initiatives differ considerably, from well-organized wind cooperatives that have grown into professional organizations to small-scale hydroelectric power plants owned by a rural community. The initiatives may have modest impact on the energy transition in quantitative terms, but they are crucial in knowledge sharing and as inspirations for future initiatives.

The Village

This paper provides survey results of an electricity system that has been carried out from isolated village of Alue Keujrun, South Aceh, Indonesia. The village has a central photovoltaic power plant and a micro hydro power plant. Various problems in the field such as operation errors, lack of maintenance of the electric power system, low voltage and frequency have been found. Power plant operators have also never received any formal training from any institution. The village is located next to the Kluet river which has a very large potential to become a hydrokinetic power plant energy source. Therefore the Kluet river flow velocity was also measured during the survey and described within this paper. Based on the interviews results with local operators, the village power plant does not have an operating permit. Thus, we consider that it is important to review the types of permits required to establish a power plant in Indonesia, including small-scale power plants.

Technical And Economic Indicators

In our country, a lot of attention is paid to the development of the energy sector. A lot of work is underway to modernize existing capacities and commission new capacities. At the same time, the unit capacities of units and power plants also increase, which ensures faster commissioning of capacities in the power system and an increase in the efficiency of power plants. Attention is also paid to the development of power plants based on renewable energy sources (hydraulic, solar, wind, etc.). One of the most important tasks in the power industry is to cover peak minimum and maximum loads, which is becoming increasingly important in connection with the growth of the power system's capacity. As is known, according to world indicators, the maneuverable capacities should be about 25% of the total power of the EPS. The most promising maneuverable capacities are hydroelectric power plants. However, in our country, hydroelectric power plants account for about 14.3%. This task will become more complicated with the introduction of capacities based on solar and wind energy and the commissioning of new hydroelectric and thermal power plants in the Republic. This is because RES capacities have a significant discontinuity even during the day, and the water resources in the Republic are primarily for irrigation and drainage purposes and are significantly variable during the season. One way to solve these problems in the world is the creation and use of pumped storage power plants (PSPP). The peculiarities of the creation and use of pumped storage power plants in our region are that the available hydro resources of our region are mainly of water management importance, while the task is also to increase the energy efficiency of existing reservoirs. Based on the foregoing, we can say that the development of methods for determining the economic efficiency of pumped storage power plants, taking into account direct and indirect effects, taking into account the peculiarities of their use in energy and water management systems of Uzbekistan is the main task for the present time. To solve the set tasks, a new methodology and program for substantiating the technical and economic indicators of pumped storage power plants in Uzbekistan's energy and water management systems have been developed. The schemes of using pumped storage power plants at four energy and water management facilities, that is, the Tuyamuyun hydro subunit, Arnasai, Talimarjan, and Khodjikent reservoirs, were considered, and for these facilities, based on the developed methodology and program, their technical and economic parameters of the pumped storage power plant were determined. Based on the results obtained, it can be said that using the PSPP in four facilities, it is possible to generate a total of about 418 MW of capacity and more than 930.0 million kWh of electricity, as well as to save 139 thousand tons of fuel equivalent per year, with this, the annual economic efficiency will be about 700.0 billion sums.

The Republic

Cuba is traditionally considered a country with an underdeveloped industry. The share of the mining and metallurgical industries in the gross industrial production of the republic is small – about 3 % of GDP. The development of deposits and the extraction of nickel ores is an important sector of the economy of the Republic of Cuba, since the largest reserves of nickel and cobalt on the North American continent are located on the territory of the country. The development of the country energy system can serve as a growth factor in this sector of the economy. Due to climatic features and impossibility of integrating new capacities into the energy system through the construction of hydroelectric power plants, solar energy is a promising direction. Determining the feasibility of using solar tracking systems to increase the generation of electricity from solar power plants is one of the main challenges faced by engineers and renewable energy specialists. Currently, there are no solar tracking systems in Cuba that can provide information to assess the effectiveness of this technology in the country. The lack of the necessary technologies, as well as the high cost of developing solar power plants with tracking systems, limit the widespread introduction of such complexes. Hence follows the task of creating an inexpensive experimental model that allows assessing the effectiveness of tracking systems in specific weather conditions of the Republic of Cuba. This model will allow in future to increase the efficiency of electrical complexes with solar power plants, which provide power supply to the objects of the mineral resource complex and other regions.

"The article presents an overview of the technical, economic, and environmental arguments in favour of wider use of the gigantic energy potential of sea tides to solve the most important climate problem today – the reduction of anthropogenic pollution of the Earth's atmosphere with carbon dioxide. The main idea of the considered solution is the replacement of carbon fuels for thermal power plants and transport with ""green"" hydrogen. The production of such hydrogen is carried out by electrolysis using the energy of carbon–free renewable sources. Tidal hydroelectric power plants are the cheapest, largest and most economically safe electricity supplier for the production of green hydrogen today. Until now, this direction of the energy sector has not become widespread due to the high capital intensity, as well as due to the geographic remoteness of the places where tidal energy is concentrated from large centres of electricity consumption. The explosive growth in global hydrogen demand in recent years alleviates the problem of very expensive transport and large losses in long distance transmission of electricity. Hydrogen can be transported without loss and relatively cheaply by pipelines and sea tankers over unlimited distances. The use of the energy of the highest tides and flow in the Pacific Ocean for the production of ""green"" hydrogen is proposed in the revived project of construction of the world's largest Penzhinsk Tidal Hydroelectric Power Plant (the Sea of Okhotsk’ north–east, Russia)."

The article considers the specific features of public services delivery in the Republic of Kazakhstan and other countries where public services are provided with the involvement of different models of electronic government. Today, state provision of public services to citizens is becoming one of the most important spheres of the functioning of government authorities. The notion of public services has become an object of focused scientific research relatively recently in the Republic of Kazakhstan, while in developed countries, the relationship between the state and society, where the state is viewed as a service provider, developed in the 1980–1990s. The aim of this paper is to analyze the current state of the sphere of public services provided to the population of the Republic of Kazakhstan and to study international experience in this area. The authors view public services delivery as a process of information interaction between the state and society, which, at the current stage of IT development, is increasingly taking an electronic form. The authors explore historical and theoretical prerequisites for the creation of the modern system of public services, the current state of the corresponding organizational and legal framework in the Republic of Kazakhstan, and international experience of development and implementation of successful patterns of public services delivery. Besides, the authors study the specific features of legal regulation pertaining to handing public services over to a competitive environment. The article assesses the possibilities of further use of advanced technologies to address the tasks for which this important element of government control has been developed. The results obtained by the authors consist in the validation of the conclusions about the assessment of the public services sphere and its organizational and legal grounds, as well as the potential for its further development. The paper includes several suggestions for improvement of the organizational and legal framework of public services delivery. The novelty of this article consists in the fact that the authors suggest ways of further development of the interaction between the state and society based on thorough analysis of world practices of public services delivery
