Abstract To tackle climate change and secure energy supplies, many countries invest heavily on wind energy as it is a clean source and is becoming more cost effective with the technological advancement and increased capacity per unit installed. The investigation of the availability of wind resources is an essential step of any feasibility study of a wind farm project and is vital for securing financial resources. With this intent, the main aspects for designing a wind farm at Ajloun (north of Jordan) is investigated and wind energy potential is determined based on available wind data. Based on the site characteristic, the required infrastructure is highlighted, including the turbine array layout and the pattern of connections with the external transmission lines. The investigation of the feasibility of the project includes an appraisal of social and environmental consequences of constructing the wind farm project. The results show that the selected location for the wind farm is encouraging and has a promising profit potential. The findings estimate the annual electricity generation of the wind farm at 379659.51 MWh, with a breakeven selling point of around $30.03/MWh, at a highly competitive price. However, with an estimated selling price of $36.65/MWh on average, it will settle the interest rate demanded by the banks that have an internal rate of return of 7%. No major issues with geotechnical and environmental issues were identified with respect to the project.

Sustainable economic growth and increase in the level of population wellbeing, the diminution of energy dependence of Ukraine from the neighboring countries can only be achieved through the use of different types of biofuels, the practice of which is confirmed by the experience of other countries. One of the most promising types of fuel is agricultural plants, or rather the waste that remains after harvesting. The purpose of this study is to assess the energy potential of agricultural plants in Ukraine on the example of the Lviv region with an idea that it might reduce the energy dependence of Ukraine on Russia and other countries and will become a basis for improving the national energy management system. Assessment of the energy potential of agricultural plants was carried out on the example of the Lviv region. This assessment is based on all three components of the energy potential of agricultural plants (both theoretically and technically feasible and economically justified).According to the results of calculations, waste of wheat, other grain crops and rape has the largest energy potential. In particular, the energy potential of agricultural biomass of the Lviv region makes theoretically possible (maximum) 2.1 million tons of fuel equivalent, technically achievable 0.915 million tons of fuel equivalent (including losses), and economically expedient (optimal) 0.74 million tons of fuel equivalent. The evidence revealed in the study confirmed the fact that Ukraine has sufficient energy potential use of agricultural crops. All these measures correspond to the state strategy for the development of the energy potential of Ukraine. Considerable attention is paid to the need to form an optimal management system for the use of energy potential of agricultural plants in Ukraine. Given the significant economic efficiency of agricultural wastes, the expediency of its use as biofuels has been substantiated. The most effective in energy terms are grain crops (wheat, barley), which should be preferred in the process of biomass creation.

The demand for new energy sources is growing and awakening interest in the use of forest residues. Charcoal was prepared at carbonization temperatures of 500 ºC, 600 °C and 700 °C in order to evaluate the potential use of Pinus sp needles for energy. The anatomical and chemical characteristics of the needles and the charcoal produced were also evaluated. The needles were found to have ash content of 2.32% and gross calorific value of 20.30 MJ/kg. The calorific value increased by 45%, reaching 29.64 MJ/kg, after carbonization carried out at 600 ºC. This value is higher than that for charcoal made from eucalyptus (19.25 MJ/kg) and even coconut husks (23.55 MJ/kg), showing the high energy potential of these needles.

Intisari  — Setiap yang berputar memiliki potensi energi kinetik, tidak terkecuali putaran kubah masjid. Penelitian ini bertujuan untuk mengetahui potensi pemanfaatan kubah putar masjid sebagai penghasil energi listrik skala kecil. Generator yang diuji cobakan adalah generator magnet permanen dan generator DC yang dirangkaikan dengan turbin kubah putar. Pengujian dilakukan di dua lokasi, di Jembatan Musi 2 Palembang dan di perairan Sungsang Kabupaten Banyuasin untuk mengukur besaran tegangan dan arus output yang dihasilkan pada berbagai kecepatan angin menggunakan multimeter dan anemometer. Hasil penelitian menunjukkan bahwa tegangan yang dihasilkan oleh putaran  kubah masjid menggunakan generator magnet permanen mampu mencapai 14,21 V pada kecepatan angin 3,8 m/det dibandingkan dengan generator DC yang hanya mencapai 3 V pada kecepatan angin 8 m/det. Jika ditinjau dari besaran arus, generator magnet permanen menghasilkan arus konstan sebesar 0,3 A sedangkan pada generator DC arus yang dihasilkan tidak terukur karena nilainya yang amat kecil. Penelitian ini menunjukkan bahwa kubah putar masjid dapat dijadikan sebagai turbin angin pada daerah yang memiliki kecepatan angin rendah. Kata kunci  — kubah masjid putar,generator magnet permanen,generatorDC, turbin angin kecepatan rendah       Abstract - Every spinning has kinetic energy potential; the mosque dome is no exception. This study aims to determine the potential use of the mosque's turning dome as a producer of small-scale electrical energy.  Two types of the generator were tested, which were permanent magnet generator and DC generator, which were coupled with a rotary dome turbine. The test was carried out at two locations, at Palembang Musi 2 Bridge and in the waters of Sungsang, Banyuasin Regency, to measure the amount of voltage and output current generated at various wind speeds using a multimeter and anemometer. The results showed that the voltage generated by the mosque's dome rotation using a permanent magnet generator was able to reach 14.21 V at wind speeds of 3.8 m / sec compared to DC generators, which only reached 3 V at 8 m / s wind speed. When viewed from the amount of current, permanent magnet generators produce a constant current of 0.3 A while in DC generators, the current generated is not measurable because the value is minimal. This research shows that the mosque's rotary dome can be used as a wind turbine in areas that have low wind speeds. Keywords - rotary mosque domes, permanent magnet generators, generator DC, low speed wind turbines

Composite maps have previously been applied to paleogeographic reconstructions and as an aid to mineral exploration. However, because they can combine different criteria that are used in risk and feasibility assessment into a single map with equal or weighted input from all the parameters, decisionmaking can be optimized. The methodology is particularly suitable for the evaluation of landslide hazard and susceptibility assessment, as it can combine the unfavourable factors typically associated with mountainous terrains. Composite maps also have the potential to standardize prediction and prevention criteria for different areas. The methodology is described together with an hypothetical example and a real case study in Patagonia, the results of which are compared with a susceptibility analysis of the same area using stochastic methods

The article presents the results of a cadastral fisheries survey of a group of riverbed ponds located within the boundaries of certain municipal districts of the Kursk region in the summer of 2019. The comparative fishery characteristics of water bodies based on a complex of morphometric, hydrochemical, hydrobiological and ichthyological indicators are presented. The question of the potential use of this group of water bodies for pasture aquaculture is considered based on the results of their bonitirovochnoy assessment for a number of fish-breeding indicators.
