Energy security and independence is one of the key points in sustainable development. In modern conditions of rapid growth and development of technologies, more and more attention is paid to finding practical solutions for environmentally friendly and inexpensive energy production. For a long time, scientists from various fields of scientific activity around the world have been engaged in the development and use of alternative energy sources. The share of renewable energy sources in the generation of electricity around the world is growing steadily, which indicates an increase in the use of energy obtained from alternative sources, such as, for example, wind and sun. These trends testify to the desire of consumers to abandon the use of fossil energy sources and nuclear power plants as much as possible in order to ensure further sister development. Under the current conditions of the COVID-19 pandemic, the demand for electricity worldwide has decreased, however, as the study shows, this pandemic has not affected the development of renewable energy. The article analyzes modern trends in the development of renewable energy, taking into account the experience of the EU countries and leading countries of the world in this area. As a result, it was concluded that in modern conditions, to achieve sustainable development, transformation processes are needed in such an important area as energy. Various processes in the global economy, which contributed to the intensive development of alternative energy sources, served as a powerful impetus for such changes. Many countries have made significant progress in the development of renewable energy.

Aquaculture Production

The rapid growth of aquaculture production has required a huge power demand, which is estimated to be about 40% of the total energy cost. However, it is possible to reduce this expense using alternatives such as renewable energy (i.e., solar energy) instead of non-renewable energy. Solar energy is one of the cleanest energy sources and is touted as a potential renewable energy source for the world with benefits such as reducing CO2 emissions, reversing global warming by being eco-friendly, and bringing innovation to sustainable aquaculture and potential cost-efficiency for manufacturing. In this review, we present an overview of using non-renewable and renewable energy sources for aquaculture by reviewing several articles and applications of solar energy at many companies in the world. Moreover, this review shows potential and future trends using solar energy for aquaculture.

The fact that the current energy production resources have a tendency to be extinguished rapidly, the raw material prices have increased, their negative effects on the environment and human health, some difficulties in their use have increased the studies conducted on new and renewable energy sources in recent years. Among the renewable energy technologies, even though it is somewhat expensive, the easiest technology in terms of design and installation is the photovoltaic technology which is an application of solar energy. But its real superiority arises from the fact that it is a technology that does not pollute the environment, is environmentally friendly and has low maintenance costs. The use of solar energy has increased considerably with the increase in the use of renewable energy sources in the world and in our country in recent years and the roofs have had the largest share in this regard. Considering that more than 50% of the installed facilities in Germany and Italy, which are the starting point of solar energy in Europe, are on the roofs, the roofs have an important place in the increase of solar energy usage. Turkey is in fortunate situation compared to many countries in terms of the solar energy potential due to its geographical location. South Eastern Anatolia Region is the region that receives the most solar energy, this is followed by the Mediterranean Region. The logistics sector has recently been one of the sectors in which the solar energy is widely used in the world and in Turkey. In particular, significant reductions have been achieved in logistics costs with the solar energy systems installed on the roofs of the logistics warehouses, this event have increased the competitiveness of the companies. In addition, it is known that solar energy has been started to be used in the transportation activities and there are R & D studies for increasing road vehicles and cargo ships working with solar energy. In addition, efforts are being made to improve the solar-powered highways which strengthen the transport infrastructure and the logistics processes and these applications are becoming widespread. In study, the solar energy which is one of the mostly interested one among the renewable energy forms and the photovoltaic technology producing electrical energy using it will be discussed in this context, an then the current situation in Turkey and the World will be presented. Finally, the usage of the solar energy in the logistics sector and the applicaton examples in the world and in Turkey will be included.

Energy security and stability are currently the main issues throughout the world. Applied research is carried out all over the world in order to increase a share of renewable energy sources in the overall task of energy generation. In near future environmentally friendly energy sources should be found that will enable the mankind to cover its energy needs. Renewable energy sources are currently offered worldwide as an environmentally friendly and acceptable solution; however, one may always wonder whether it is realistic to expect such energy sources to be developed at a level sufficient to meet the mankind’s ever increasing energy needs. This caution is caused by the following facts associated with the renewable energy sources available today: the wind energy is not everywhere available in sufficient quantities, solar energy is not sufficiently used, hydropower (we refer to small hydro power plants), is not big enough for this quantity of energy, geothermal energy can be optimally used only at places where thermal energy from the inner core of the Earth is near the surface, tidal energy (energy of the waves) has great potentials but is very little used due to its scarcity and non-accessibility, bioenergy, as a substitute for conventional fossil fuels, is not completely environmentally friendly or acceptable due to the emission of greenhouse gases in the atmosphere. On the other hand, without implementing the adequate policies in the energy sector operation, it is not possible to have any industrial, economic or social progress in the world. Energy security and stability are only one part in achieving the ultimate goals: sustainable economy, clean environment, high standard of living, prosperity and health of the population. In the light of all the above, the paper will investigate the state and perspective of renewable energy sources with a special emphasis on the potential of solar energy.

The article provides an overview of the current state of energy in the world and in Russia, which focuses on the development of renewable energy sources (RES). An analysis is made of the trend in the production and consumption of energy resources, as well as an assessment of the use of renewable energy in Russia. Incentives for the development of renewable energy sources with the characteristics available in the world are determined. Conclusions are drawn about the importance of developing this industry both in Russia and in the Chechen Republic, as one of its regions. An assessment is given of the development of wind and solar energy in Russia. The current power supply structure of the Chechen Republic is considered, where the indicators of maximum electric power, consumed electric power, and also electric power generation of the republic are given. The analysis of the possibility of using wind and solar energy resources, as well as small hydropower of the Chechen Republic. Options for the development and effective use of renewable energy sources are considered, taking into account the fact that the use of energy resources based on modern innovative technologies, the introduction of new promising alternative sources, and the search for ways to stimulate the use of renewable energy sources, where it is supposed to organize and introduce a tariff policy, is one of the main tasks of energy development which give a complete systemic idea of the scale of the problem of transferring the energy system to innovative rails. Some options are proposed for the most expedient development of the energy system of the Chechen Republic, the construction of small pilot plants using renewable energy sources, with the goal of actual (experimental) confirmation of the predicted calculated values, as well as the gradual mass introduction of plants using renewable energy sources in the private sector with the creation of the necessary tariff conditions for use and construction installations on an industrial scale within the framework of energy private or public companies. Priority tasks have been set for the prospective development of the republic’s energy sector by introducing renewable energy sources.

According to the Eurostat database, the percentage of renewable energy sources in the energy mix of the EU is increasing year after year (www.europa.eu/eurostat). In 2018, the values reached 73% in neighboring Austria (48% in Croatia, 42% in Romania, 32% in Slovenia and 21% in Slovakia), Hungary now stands at 8%. Wind energy is the leader in the renewable energy structure of the EU countries (35, 8% in 2018), since the construction of wind farms is prohibited in our country, one of the main objectives of research is to examine our energy structure. Our last position in renewable energy in 2020 prompted the government to develop a new climate strategy (mekh.hu/nemzetienergiastrategia2030). According to the new strategy, Hungary is estimated to be climate and carbon neutral by the end of the decade. Among the alternative sources of energy, solar energy is becoming the favorite, and our article points out why other forms of energy are being overshadowed. Analyzing the changes in the country’s future energy mix, it can be said that it will be based essentially on nuclear power and electricity from Russia’s electricity grid. However, due to the drastic drop in the cost of solar panels in the energy mix of households, solar energy has become a favorite of renewable energy sources. In the climate strategy, the government plans to create 8,000 MW of solar energy by 2050, which will be mainly used in households, municipal buildings, and tourism.

The energy transformation towards renewable energy sources in the conditions of climate change and the accompanying climate risk is a priority for all countries in the world. However, the degree of advancement of activities in this area varies significantly between countries, which is the result of different activities for renewable energy sources in individual countries. The aim of this article is to determine the trends of changes in the area of the use of renewable energy sources in EU countries. The study uses TMD (taxonomic measure of development) methods and dynamic classification, which allowed to distinguish typological groups of objects with similar dynamics of the studied phenomenon. The EU 28 countries were analyzed. Statistics (Eurostat database) are provided for the period 2004–2019. As a result of the research, it was found that the Scandinavian countries and the countries of Western Europe were characterized by the highest stability in terms of the use of renewable energy sources over time. These countries also recorded the smallest increases in TMD. On the other hand, the unfavorable situation in terms of stability was observed mainly in the countries of Southern Europe.

The world energy consumption was about 567-578 EJ in 2017 which is still increasing – in 2017 by 2.2%, and yearly by 1.7% on average since 2006 (BP, 2018, IEA, 2018). Within this, the consumption of residential segment plays a significant role both in the EU (42%) and in Hungary (35%) as well (Eurostat, 2019). The Hungarian population spend 12.8% (35 EUR/capita/month) of their income on energy sources, and this rate is even higher in case of the pensioners, singles and those who have lower income (KSH, 2019). At the same time, the rate of renewables in the energy mix stagnates for years worldwide (14%), it is a bit higher in the EU and in Hungary than the world average (18-18%, IEA, 2018). Thus, the renewable energy sources can also have serious perspectives in the residential cost reduction, in the sustainable energy consumption and in the local income production. Our aim is to analyse the knowledge of Hungarian consumers on renewable energy sources, their willingness to apply them and the socio-demographic factors on these. To execute the research objectives, a national representative survey with 1000 people was started in April 2019 in Hungary. Based on the results of the questionnaire, it was concluded that the information of the inhabitants is below the average in case of every examined renewable energy source, which is especially true for the biomass-based energy sources. The ease is almost as important as the environment friendliness. An excessively high rate of respondents (34 and 27%) is interested in solar panels and solar collectors, 32% of them seclude themselves from the use of these energy sources. It would be justified to extend these consumer researches in the future for more countries. The authors wish to clarify how the differences in location, income status and residential segment and values influence the spread of these energy sources in the EU and by which tools could support the usage of these in the future.
