Over 90% of Uganda's power is generated from renewable sources. Standardised Implementation Agreements and Power Purchase Agreements create a long-term relationship between Generating Companies and the state-owned off-taker guaranteed by Government. The COVID-19 pandemic and measures to curb the spread of the virus have triggered the scrutiny and application of force majeure (FM) clauses in these agreements. This article reviews the FM clauses and considers their relevance. The authors submit that FM clauses are a useful commercial tool for achieving energy justice by ensuring the continuity of the project, despite the dire effects of the pandemic. Proposals are made for practical considerations for a post-COVID-19 future which provides the continued pursuit of policy goals of promoting renewable energy sources and increasing access to clean energy, thus accelerating just energy transitions.

The article is aimed at developing strategic directions and introducing regulatory measures for the formation of Ukraine’s energy policy on the principles of energy saving and the development of renewable energy industry. On the basis of scientific works, the main organizational-economic vectors of energy industry sector development are systematized, which are associated with the formation of a favorable socio-political climate regarding the priority of using renewable energy sources in the fuel and energy complex; development of effective methods of both the State-based and the market-based regulation by the world community; coordination of the strategy of sustainable development of the world economy. It is determined that the energy saving policy should be based on a flexible combination of the State-based regulation and the market environment for the formation of the most acceptable stimulation mechanisms in the specific economic and political situations, which allows for the greatest economic benefit. It has been found out that the implementation of energy saving processes is impossible without the mass use of renewable energy carriers, which are a universal resource for processing to the right types of energy, are marked by energy independence related to obtaining economic benefits and contribute to the creation of an ecological friendly environment. In the perspective, the energy saving processes, the transition of the national economy to wide implementation in the production of high-tech technologies and the use of renewable energy sources should become the determining factors of Ukraine’s energy strategy.

Sustainable development, as a generally accepted concept of modern society, implies the protection of the environment as one of the basic goals. This goal is achieved, among other things, through the use of renewable energy sources and energy efficiency. The improvement of energy efficiency and application of renewable energy sources should be incorporated while preserving the economic interests of the state. In order to harmonize these interests, the state must introduce the policy in the field of energy, which will simultaneously take care of both the environment and the economy. Among the most important instruments of such a policy are legal regulations. The Republic of Serbia has an extensive and thoroughly structured system of regulations in the field of energy efficiency. The mere existence of regulations in this area is not enough. It is only a necessary precondition for their consistent application, as well as control of the application by inspection bodies.

The article aims to develop a set of objective criteria for assessing the state of energy security in decentralised remote regions of the north, Arctic zones and autonomous energy supply complexes. The authors assessed the potential of renewable energetics, which determines the effectiveness of decentralised energy complexes based on renewable energy sources, in improving the energy security of such entities. The indicators for assessing the energy security of research objects were developed on the basis of an analysis of the ratio of the most significant threats, as well as territorial and situational factors of the autonomous energy of the north and Arctic zones. A study of the security of the research objects allowed the development of a set of criteria for territorial segments and autonomous electrification objects, forming an objective assessment of the energy security of isolated hard-to-reach areas. An analysis of the possibilities of renewable energy sources in achieving certain positions (resource sufficiency, environmental acceptability, technological attainability and reliability) of the energy security of the considered level was conducted. Groups of properties and processes within the territorial framework of a decentralised region, separated by the directions of monitoring the energy security of local energy zones are proposed as objects of indicative analysis. The differentiation of the developed criteria by the levels of the energy zone and decentralised energy complex allowed consideration of all the specific features of these objects and cover the factors of mutual influence with accompanying systems in the formation of the state of energy security. When considering a possible option for the participation of renewable energy sources in the structural and resource provision of autonomous electricity supply, it was found that such diversification will affect both the improvement of some criteria of energy security of the considered level, as well as the deterioration of others.
