Wind power is a source of renewable energy produced by harnessing the kinetic energy of the wind. Wind energy is converted into electricity using wind generators or wind turbines installed in wind farms. It is linked to the kinetic energy of the wind, which is produced when air moves. The energy can be used to create mechanical motion, such as the rotation of the rotors of a wind turbine. To harness wind energy, wind turbines or generators are installed to convert the kinetic energy of the wind into electricity. A...

Georgia's positioning in the context of the European Union's foreign energy policy has become the subject of discussion in the context of the threats coming from the current Russia-Ukraine war. At the same time, determining the effectiveness of the country's energy policy is related to the seventh Sustainable Development Goal - affordable and safe energy. In 2016, Georgia signed the protocol of joining the Energy Community, which determines the conditions for the introduction of EU energy legislation in Georgia in...

The present research explores the integration of a photovoltaic system for an educational building through a comparative analysis using the PVsyst and Simulink platforms. The building, intended for university education, is located in Cluj-Napoca, Romania. Considering the building-s location and specific climate, the feasibility of installing a photovoltaic system was analyzed with the aim of reducing electricity consumption from the electrical grid. The study began with a PVsyst simulation, which indicated that a ...

In light of the pressing need to achieve climate neutrality in the energy sector, the European Union seeks to identify strategies that will enhance and diversify its green energy supplies. As a renewable energy source, green hydrogen promises to offer a viable alternative to fossil fuels where green electricity may be insufficient or inaccessible. This is why the production and supply of this innovative energy carrier is becoming a significant focus in EU politics and research. This article examines and compares p...

Hydrogen-based energy production involves the use of fuel cells or the direct combustion of hydrogen (a particular case being hydrogen combustion in internal combustion engines). Direct hydrogen combustion is still in the testing phase, with challenges arising from its energetic properties, which continue to be a difficult factor. For instance, hydrogen has a low calorific value (about three times lower than methane) in its gaseous phase, which is the phase where combustion occurs, a very high combustion speed (ab...

Biomass is the first form of energy used by man at the same time with the discovery of fire, means all the products of animal and vegetable origin used in present in the production of energy. Actually, the biomass approximately half (44-65 %) of the total renewable energy sources used in the EU, and occupies a third place as a primary energy source in the world, after coal and oil. At the same time represents a sustainable alternative to reduce carbon emissions. The experimental territory is located in the middle ...

Based on the principles of prevention, the employer must seek to eliminate risk at source and, in order of priority, to replace hazards through non-dangers, to separate or isolate areas where there are hazards, ensuring adequate collective and individual protection. However, workers from high and very high voltage power substations continue to be exposed to occupational hazards, suffering accidents at work and occupational diseases with significant repercussions on their health, on colleagues or National Power Sys...

Hybrid electricity storage systems are becoming essential for efficiently managing renewable energy sources and enhancing the stability of power grids. As the adoption of renewables expands, these systems are crucial for balancing supply and demand, mitigating intermittency issues, and ensuring grid reliability. This paper offers an in-depth review of different system configurations used in hybrid storage systems, emphasizing the significance of understanding and optimizing their intricate designs. Recent technolo...

The SWOT analysis of the energy resources of hydrocarbons comes in the context in which the possibility of a black-out is very likely, and the lack of energy resources can cause major damage through enormous financial losses, which through the domino effect can spread economic and national insecurity. In this context, the SWOT analysis energy resources become an essential issue of national security and makes this paper of real interest. The authors consider that the security supply with energy resources of hydroca...
