Germany is one of the leaders in the development of renewable energy among the EU countries. Natural features and the use of new technologies allow Germany to develop actively certain types of renewable energy in its federal states. The aim of the study is to assess the renewable energy sector in the northern and southern states of Germany. In this work, the regulatory framework for renewable energy was studied; an analysis of the energy potential of the northern and southern federal states of Germany was carried out. A conclusion has been formulated about the predominance of wind energy in the northern lands, and solar and hydropower in the southern lands; about the presence of a number of problems in the renewable energy development.

The article presents the results of an analysis of literary sources. A comparison of the main types of solar collectors has been conducted. Particular attention is paid to the analysis of factors affecting the efficiency of solar power installations in the conditions of the North. The practical experience of implementing solar collectors in Yakutia is considered, demonstrating their operational viability and economic benefits.

The development of Russia's Arctic territory faces a number of challenges, one of which is ensuring reliable and efficient energy supply to isolated settlements. Traditional methods of electricity generation based on diesel plants are characterized by high energy consumption, expensive fuel transportation, and significant environmental impact. Therefore, it is crucial to explore the possibilities of integrating renewable energy sources (RES) into existing energy systems. This article explores the advantages and limitations of hybrid power supply systems that combine traditional diesel fuel with renewable energy, and examines the potential for their widespread adoption in the Arctic region of Russia.

This article presents a systemic analysis of the challenges and strategic priorities for modernizing the energy sector of the Republic of Sakha (Yakutia). The relevance of this research is driven by the unique constraints the region faces, including an extreme climate, protracted fuel supply cycles, a high share of isolated power systems, and increasing fiscal pressure from the need to subsidize inter-tariff cross-subsidies. The methodological framework of the study is based on a systems research approach applied to the energy sector. The article proposes an approach that integrates operational measures for stabilization with a long-term technological transformation. Key strategic vectors identified include: modernizing conventional generation, deploying integrated heat and cold supply systems, actively harnessing renewable energy potential, and leveraging R&D in new materials and predictive diagnostics.
