Expect: EXplainable Prediction Model for Energy ConsumpTion

With the steady growth of energy demands and resource depletion in today’s world, energy prediction models have gained more and more attention recently. Reducing energy consumption and carbon footprint are critical factors for achieving efficiency in sustainable cities. Unfortunately, traditional energy prediction models focus only on prediction performance. However, explainable models are essential to building trust and engaging users to accept AI-based systems. In this paper, we propose an explainable deep learning model, called Expect, to forecast energy consumption from time series effectively. Our results demonstrate our proposal’s robustness and accuracy when compared to the baseline methods.

Use of Hydrogen as Fuel: A Trend of the 21st Century

The unbridled use of fossil fuels is a serious problem that has become increasingly evident over the years. As such fuels contribute considerably to environmental pollution, there is a need to find new, sustainable sources of energy with low emissions of greenhouse gases. Climate change poses a substantial challenge for the scientific community. Thus, the use of renewable energy through technologies that offer maximum efficiency with minimal pollution and carbon emissions has become a major goal. Technology related to the use of hydrogen as a fuel is one of the most promising solutions for future systems of clean energy. The aim of the present review was to provide an overview of elements related to the potential use of hydrogen as an alternative energy source, considering its specific chemical and physical characteristics as well as prospects for an increase in the participation of hydrogen fuel in the world energy matrix.

Research on the Anthropogenic Impact on Climate Change

The article is a presentation of the results of studies and calculations of climate parameters associated with anthropogenic thermal pollution of the environment. They indicate that the increase of atmospheric concentrations of carbon dioxide, methane, and nitrous oxide cannot be a cause of climate warming. The article provides information about the working principle of the natural mechanism of automatic maintenance of temperature climate parameters. The authors show that all of the gases molar mass of differs from the molar mass of nitrogen are the working bodies of the procedures for moving heat from the stratosphere to space. Water vapor is the only greenhouse gas, and to deal effectively with water vapor in the atmosphere is impossible. However, the work contains an assessment of the feasibility of some ways to assist the natural mechanism of removing heat to space. Some methods and tools of world energy development are suggested in the article. These methods could lead to a substantial reduction of anthropogenic thermal pollution of the planet.

PV Based Automatic Irrigation System

In Because of the lack of rains and scarcity of land reservoir water, proper irrigation methods are critical in the field of agriculture. The continuous extraction of water from the earth is lowering the water level, causing a lot of land to slowly come into the unirrigated zones. Another important reason for this is because of unplanned water use, which wastes a significant amount of water. This automatic plant irrigation system is used for this purpose. Solar energy is used to power the system via photovoltaic cells. As a result, there is no need to rely on erratic commercial power. In this digital age, we demand that everything around us be automated, reducing human effort. Electronic circuits are becoming more prevalent, making life easier and simpler in today's world. Energy and water scarcity are two major issues that everyone is dealing with these days. As a result, energy and water conservation are required. The goal is to create a solar-powered prototype that will automatically irrigate the field. Consider how convenient it will be to be able to focus on your next task while your field is being irrigated automatically and at a low cost. No worries about underirrigation or over-irrigation, water waste or expensive electricity, or your busy schedule.

Global trends and target indicators of economic development of industrial gas production complexes in the Arctic

The current stage of development of the world energy sector is characterized by high turbulence and dynamism of changes. The volatility of demand and prices for energy resources, increased competition in the global market, the evolution of the energy balance, the decrease in the role of traditional hydrocarbons and the progressive development of technological innovations significantly affect the efficiency of the implementation of the Russian gas complex in the Arctic. However, in addition to economic benefits, large-scale production of natural gas in the Arctic encompasses a wide range of issues: ensuring domestic needs for hydrocarbons and stable exports, minimizing environmental damage, organizing complex science-intensive industries and loading industrial capacities, developing transport and social infrastructure, creating new high- tech work places. In these conditions, long-term prospects and assessment of the development efficiency of complex industrial gas production complexes are determined taking into account environmental, economic, technological and social aspects. The analysis of the factors of instability of the world energy system and their influence on the efficiency of the development of gas fields in the Arctic zone was carried out. Target guidelines for the development of the Russian gas industry have been formulated in the context of national interests and priorities of socio-economic development and environmental safety. Indicators of economic development of industrial gas production complexes are proposed, takinging to account trends in the global energy market and the specifics of field development in the Arctic.

The Eastern Mediterranean in UAE Foreign Policy: Goals and Principles

The Eastern Mediterranean in recent years has become an arena of growing activity of regional states causing tensions among them. The importance of this region from political and military point of view combined with its strategic value in the world energy markets underpins the growing involvement of the UAE, a non-regional actor that lately has become deeply engaged in the regional agenda. Due to the fact that the UAE has taken up a quite active foreign policy course outside of its traditional Gulf circle only recently - with the Eastern Mediterranean becoming a new area of Emirati activities - the volume and scope of Russian and foreign research on this topic is rather limited. The existing works that in some way cover issues of the UAE foreign policy do not reflect the increasing influence of this small Gulf state in the Middle East and North Africa and beyond. For this reason, there is a need for complex research on the matter. This paper is based on analysis of existing works on topics related to some aspects of Emirati foreign policy and tensions in the Eastern Mediterranean, as well as analytical articles and statistics. The dramatically increased interest of the UAE in the Eastern Mediterranean is part of significant transformations in the monarchys foreign policy that have been taking place since early 2010s. These transformations manifest themselves in new goals and purposes of Emirati foreign policy, its expanding scale and new instruments for its implementation. Not only is the UAE policy in the Eastern Mediterranean consistent with its general goal of containing Turkey and fighting the threat of Islamism, but it is also a part of realizing Emirati global ambitions of becoming a leader in energy and logistics and ensuring its international status as an influential actor.

Forecasting the Mix of World Energy Needs by mid-21st Century

The logistic function is used to forecast energy consumed worldwide. The logistic substitution model is used to describe the energy mix since 1965 presenting a picture significantly different from the one covering the previous 100 years. In the new picture the share of heavy pollutants, i.e. coal plus oil, keeps declining systematically in favor of natural gas and renewables (wind, geothermal, solar, biomass, and waste), the share of which grows rapidly. The shares of these three energy sources are poised to reach around 30% each by mid-21st century. Nuclear and hydroelectric energy, both with rather stable shares, are responsible for the remaining 10%, which goes mostly to hydroelectric; Zooming into the composition of renewables we find that today’s dominant wind power is about to begin losing share to solar energy, which will overtake wind after 2024 and account for more than 90% of all renewables by mid-21st century, by which time geothermal, biomass, and other sources of energy will have dropped to insignificant levels. Forecasts in exajoules are given for all energy sources up to 2050.
