AbstractEnsuring the energy resources needed for the functioning of society as a whole is a major concern for European countries, which must identify solutions in this regard. Measures to be taken individually and collectively aim to ensure a continuous flow of energy resources and to consolidate the energy security. The energy security of European states is quite difficult to achieve due to the energy situation of all states and due to the increased dependence on energy resources outside the European space. Ensuring energy security not only creates the conditions for the development of society, but also strengthens national security, as it eliminates possible sources of tension and contradictions, which can lead to crisis or even conflict. From this perspective, it is clear that the EU is making efforts for energy sources diversification and to reduce the likelihood of malfunctions, but the evolution of the energy situation of the EU bloc shows that this is a long-term approach and concrete measures are very difficult to implement, fact easy to notice from the analysis of the energy situation of the EU between 2014 and 2018.

Saudi Arabia fully depends on fossil fuels such as oil and natural gas to generate its electricity. Fossil fuels may have limited life and a history of fluctuating costs, which will lead to multiple issues that can affect the energy security of this country in the long-term. Critical Infrastructure Protection (CIP) is a concept different to “energy security”, which must consider the solar and wind energy as basic sources of energy supplies in Saudi Arabia. Monte Carlo Simulation (MCS) and Brownian Motion (BM) approaches were employed to predict the future behaviour of solar and wind energy, along with long-term temperature performance, based on 69 years of historical daily data. MCS and BM were employed to provide a wide range of options for future prediction results. A validation exercise showed that the north-western region was the most highly recommended region for deployment of solar and wind energy applications due to an abundance of solar and wind energy resources with low temperature supported by a clearer sky during the year. This is followed by the southern region, which exhibited good solar and wind energy resources. This study can be considered as a roadmap to meet the climate and sustainability goals by providing a long-term overview of solar energy, wind energy, and temperature performance in some countries that have a lack of long-term future prediction analysis such as Saudi Arabia.

Due to the increase in demand for energy resources and the effect of the ongoing events in the region of Jordan. The energy resources are decreasing over time and that also has a negative effect on the Jordanian economy. Providing energy is always a vital and significant problem in Jordan. Jordan on the other hand is a rich in some of the renewable energy resources, which are not fully used until this moment. Therefore, it is essential to find alternative and renewable energy resources. Moreover, there is also a lack in creating a clear and long term future plans in the energy field. In this paper, energy sources and the efficiency of the energy sector in Jordan will be specified, in addition to the determination of the cofounders and sponsors for enhancing and developing the energy sector. The shift in policy that is needed to increase this efficiency will be also investigated.

The paper is devoted to the standing Scientific Workshop “Methodological problems in research on reliability of large energy systems”, which was organized in 1973 in Irkutsk at the Siberian Energy Institute of the Siberian Branch of the USSR Academy of Sciences as a nation-wide workshop. Nowadays it is the International Scientific Workshop named after Academician Yu. N. Rudenko, which is well known in the community of scientists and experts in the energy sector of Russia, the former Soviet republics and other countries. Energy systems (ES) — those based on electricity, gas, oil and oil products, heat, etc., though diverse in terms of their physical nature, structural properties and specifics of functioning, have a certain commonality in the processes of production, transportation, distribution and storage of energy resources. Moreover, the interconnections and interdependence of energy systems within the fuel and energy sector, especially in emergency conditions, make it possible, at a necessary level of abstraction, to use identical techniques and methods of research, and ensure their reliability. All this allowed Yu. N. Rudenko, the organizer of the scientific workshop, to assign the workshop with its cross-sectoral status. In 2018, the workshop celebrated its 45-year anniversary; the workshop had come to the date as a recognized and highly respected international intellectual platform for discussing and solving urgent issues of reliability of energy systems, crosssectoral problems of studying and ensuring reliability and energy security. The paper presents a wide range of problems of ES reliability considered at the workshop sessions, as well as the results of solving the same. Special attention is paid to works initiated by the workshop and fulfilled using the results of studies of the workshop on unification of terminology in reliability of ES and energy security, the development of a concept of reliability in power industry and interstate technology reliability standards harmonized with international standards. The workshop continues to function successfully owing to its activities related to the integration and development of knowledge in the field of reliability of energy systems and energy security.

Fluctuations in fossil fuel prices significantly affect the economies of countries, especially oil-importing countries, hence these countries are thoroughly investigating the increase in the utilization of renewable energy resources as it is abundant and locally available in all the countries despite challenges. Renewable energy systems (RES) such as solar and wind systems offer suitable alternatives for fossil fuels and could ensure the energy security of countries in a feasible way. Zimbabwe is one of the African countries that import a significant portion of its energy needs which endanger the energy security of the country. Several studies in the literature discussed the feasibility of different standalone and hybrid RES either with or without energy storage systems to either maximize the technical feasibility or the economic feasibility; however, none of the studies considered maximizing both feasibilities at the same time. Therefore, we present a techno-economic comparison of standalone wind and solar photovoltaic (PV) in addition to hybrid PV/wind systems based on maximizing the RES fraction with levelized cost of electricity (LCOE) being less than or equal to the local grid tariff where Gwanda, Zimbabwe, is the case study. The methodology suggested in this study could increase the utilization of renewable energy resources feasibly and at the same time increase the energy security of the country by decreasing dependency on imported energy. The results indicate that the PV/wind hybrid system does not only have the best economic benefits represented by the net present value (NPV) and the payback period (PBP), but also the best technical performance; where the maximum feasible size of the hybrid system-2 MW wind and 1 MW PV-has RES fraction of 65.07%, LCOE of 0.1 USD/kWh, PBP of 3.94 years, internal rate of return of 14.04% and NPV of 3.06 × 106 USD. Having similar systems for different cities in Zimbabwe will decrease the energy bill significantly and contribute toward the energy security of the country.
