AbstractSudan is an agricultural country with fertile soil and ample water resources, as well as livestock and forestry resources, and agricultural residues. Energy is one of the key factors in the development of Sudan's national economy. We present an overview of the energy situation in Sudan, with reference to its end uses and its regional distribution. We separate energy sources into two main types: conventional energy (biomass, petroleum products, and electricity) and non-conventional energy (solar power, wind energy, hydro-electric, etc.). Sudan has a relatively high abundance of sunshine and solar radiation, and has moderate biomass, hydro-electric and wind energy resources. Exploiting the available new and renewable energy sources to provide part of the local energy demand, as alternatives to conventional fossil energy, has become a major issue in Sudan's strategic planning of future energy policies. Sudan presents an important case study with respect to renewable energy, as it has a long history of meeting its energy needs by use of renewable sources; Sudan's portfolio is broad and diverse, due in part to the country's wide range of climates and landscapes. Like many African frontrunners in the utilisation of renewable energy, Sudan has a well-defined commitment to continue research, development, and implementation of new technologies. Sustainable low-carbon energy scenarios in the new century emphasize the importance of exploiting the untapped potential of renewable resources. Sudan's rural areas in particular, can benefit from this transition. The increased availability of reliable and efficient energy services will stimulate the development of new alternatives. We conclude that using renewable, environmentally friendly energy must be encouraged, promoted, implemented, and demonstrated by full-scale energy plants or collection devices, in particular for use in remote rural areas.

Sudan is an agricultural country with fertile land, plenty of water resources, livestock, forestry resources, and agricultural residues. Energy is one of the key factors for the development of national economies in Sudan. An overview of the energy situation in Sudan is introduced with reference to the end uses and regional distribution. Energy sources are divided into two main types; conventional energy (biomass, petroleum products, and electricity); and non-conventional energy (solar, wind, hydro, etc.). Sudan possesses a relatively high abundance of sunshine, solar radiation, and moderate wind speeds, hydro, and biomass energy resources. Application of new and renewable sources of energy available in Sudan is now a major issue in the future energy strategic planning for the alternative to the fossil conventional energy to provide part of the local energy demand. Sudan is an important case study in the context of renewable energy. It has a long history of meeting its energy needs through renewables. Sudan’s renewables portfolio is broad and diverse, due in part to the country’s wide range of climates and landscapes. Like many of the African leaders in renewable energy utilisation, Sudan has a well-defined commitment to continue research, development, and implementation of new technologies. Sustainable low-carbon energy scenarios for the new century emphasise the untapped potential of renewable resources. Rural areas of Sudan can benefit from this transition. The increased availability of reliable and efficient energy services stimulates new development alternatives. It is concluded that renewable environmentally friendly energy must be encouraged, promoted, implemented, and demonstrated by full-scale plant especially for use in remote rural areas.

Offshore Wind Energy

The elaboration of a methodology for accurately assessing the potentialities of blue renewable energy sources is a key challenge among the current energy sustainability strategies all over the world. Consequentially, many researchers are currently working to improve the accuracy of marine renewable assessment methods. Nowadays, remote sensing (RSs) satellites are used to observe the environment in many fields and applications. These could also be used to identify regions of interest for future energy converter installations and to accurately identify areas with interesting potentials. Therefore, researchers can dramatically reduce the possibility of significant error. In this paper, a comprehensive SWOT (strengths, weaknesses, opportunities and threats) analysis is elaborated to assess RS satellite potentialities for offshore wind (OW) estimation. Sicily and Sardinia—the two biggest Italian islands with the highest potential for offshore wind energy generation—were selected as pilot areas. Since there is a lack of measuring instruments, such as cup anemometers and buoys in these areas (mainly due to their high economic costs), an accurate analysis was carried out to assess the marine energy potential from offshore wind. Since there are only limited options for further expanding the measurement over large areas, the use of satellites makes it easier to overcome this limitation. Undoubtedly, with the advent of new technologies for measuring renewable energy sources (RESs), there could be a significant energy transition in this area that requires a proper orientation of plans to examine the factors influencing these new technologies that can negatively affect most of the available potential. Satellite technology for identifying suitable areas of wind power plants could be a powerful tool that is constantly increasing in its applications but requires good planning to apply it in various projects. Proper planning is only possible with a better understanding of satellite capabilities and different methods for measuring available wind resources. To this end, a better understanding in interdisciplinary fields with the exchange of updated information between different sectors of development, such as universities and companies, will be most effective. In this context, by reviewing the available satellite technologies, the ability of this tool to measure the marine renewable energies (MREs) sector in large and small areas is considered. Secondly, an attempt is made to identify the strengths and weaknesses of using these types of tools and techniques that can help in various projects. Lastly, specific scenarios related to the application of such systems in existing and new developments are reviewed and discussed.

Abstract Recently, more and more attention is paid to renewable energy. Recently, green energy or renewable energy is increasingly beginning to squeeze traditional energy based on the combustion of fossil fuels: coal, oil, and so on. Basically, the development of renewable energy sources comes from wind energy and solar energy. However, as recent situations in Germany, the United States and others have shown, wind energy has its drawbacks. This is, first of all, the instability of the power supply, as well as the difficulty of converting variable wind energy into direct alternating current for industrial use. Solar energy also has its drawbacks. This is the need for large areas, the need for just such sunny areas and the cleaning of solar panels from snow, dust and other precipitation. Today, there is a search for renewable energy sources in all directions, the most insignificant options are being considered, such as, for example, at the junction of fresh water, salt water, some kind of energy is released. The paper considers a method of obtaining energy using the temperature difference between day and night. At any point in the world, the temperature is always higher during the day, and always lower at night. This so-called temperature drop can be from 3 to 12.15 and more degrees, for example, in Urengoy in winter it can reach 60 degrees. It’s the same on the planets: on the moon, especially on Mars. There, the temperature difference between day and night is about 60-80 degrees, since Mars has no atmosphere.

In parallel with the rapid increase in energy consumption today, it is known that conventional energy resources will be exhausted in the near future. Renewable energy sources are becoming more important today with decreasing available fossil resources and increasing energy needs. Wind energy is a clean and renewable energy source and has a remarkable importance. Wind energy is one of the most important renewable energy sources, whose technology and use have developed rapidly and their economy has become competitive with fossil energy sources. The systems that convert the energy in the wind into electrical energy are wind turbines. Wind turbines are classified according to their rotational axes, revolutions, powers, number of wings, wind effect, gear characteristics and installation locations. Energy has become one of the most important problems of the world countries today. Energy demand, as in many countries, is increasing with each passing day in Turkey. For this reason, solutions are sought to provide the energy needed in a timely, sufficient and reliable manner. The energy needed in these solution suggestions should be provided from domestic production opportunities and local energy sources as much as possible. In this study, usability of wind energy is tried to be revealed in Osmaniye province and its surroundings. When the wind map studies in Turkey are examined, in Osmaniye Province it has been found that the presence of wind potential, it is necessary to increase the number of WPP to benefit more from the potential of wind energy.

A major challenge for developing countries is access to electricity in rural area for accelerating its growth. There are significant impediment from the utilities to extend either improved service to the rural user or provide extended hours of supply through conventional grid supply. In developing countries, the most significant challenges are technologies used to upgrade and methods for electrification, which results in poor reliability of supply and high distribution losses, leading to hindering both economic and social development, so energy planners have suggested a hybrid energy system for the electrification of rural areas. This study investigates green energy based integrated generation for rural loads. This proposed system can orchestrate with the grid as well as with the renewable energy-based generator. The wind energy has a natural variance, to satisfy the energy demand during the nocturnal and overcast period a complementary renewable energy generator is critical, or an energy storage mechanism is needed to meet the energy demand. This type of pooled exploitation and interconnection is used to improve the reliability and resilience of the grids. The integration of distributed and clean energy resource like wind generation will reduce fossil fuel emissions and provides electricity in areas which are limitedly served by unified electrical infrastructure. Hence, it is expected to develop/modify technologies available for harnessing renewable energy sources. A MATLAB/Simulink is used to build a model for a grid-wind based integrated generation. Results obtained from MATLAB/Simulink are a close match with a practical system.

Sources of energy for conventional power generation are limited and depleting ceaselessly owing to rising demand of power because of the social modernization, rising industrial growth, quick rate of infrastructure development and also technological innovation. Several developed countries have started the employment of renewable energy sources considerably to attenuate the greenhouse gases effects within the atmosphere and harmful emission. The rising demand of the power without any harmful and damaging issue, forces the eye of researchers towards renewable sources (like wind and solar) of energy. Therefore, it's minimum impact on the atmosphere. Renewable Energy sources are becoming the key contributors in the present society due to the increasing cost of oil products and decrease in the price of RES. By using natural resources energy sources like Solar and wind are providing green energy. Renewable Energy penetration is increasing worldwide day by day. Renewable power generation will introduce noticeable power quality challenges when integrated to power grid. From the aspect of RES, renewable energy generation is intermittent and non-dispatchable because of varied nature of RES. The most common PQ challenges on RE integration are frequency and voltage fluctuations in the power system caused by noncontrollable atmospheric condition and Harmonics that are introduced because of power electronic converters used in RE power generation. This paper presents an intensive literature review, conducted on emerging PQ issues owing to Solar and Wind energy systems integration and existing mitigation methods.
