The article presents a legal analysis of the features of contractual regulation in the use of renewable energy sources in the Russian Federation and foreign countries. It is noted that in the modern period, the sphere of contractual regulation of relations arising from the use of renewable energy sources remains insufficiently studied, which is why it is necessary to conduct legal research in this area, study the experience of contractual regulation in the field of electricity abroad. For the purposes of developing legal regulation, the author proposes a conditional classification of contracts on various grounds.

In this paper, a completed review of recent researches about modern power converter based electrotechnical systems (ETSs) has been carried out. In particular, power electronics (PEs) based ETSs have been investigated. The literature review consists of a standard classification of PEs-based ETSs, along with a survey on strengths and weaknesses of these devices impact on renewable energy sources. Dans cet article, une revue complète des recherches récentes sur les systèmes électrotechniques basés sur les convertisseurs de puissance modernes (ETS) est réalisée. En particulier, les ETS basés sur l'électronique de puissance (PE) sont étudiés. La revue de la littérature consiste en une classification standard des ETS basés sur les PE, ainsi qu'une étude sur des forces et les faiblesses de ces dispositifs sur les sources d'énergie renouvelables.

In September 2015 the United Nations (UN) accepted the Sustainable Development Goals (2016-2030) for mankind, including 17 Goals and 169 detailed Targets. Sustainability is understood in the wider sense by the document, considering society and economy not just as conditions for environmental sustainability, but as equally important pillar of the „building of sustainability”. Fulfilment of these goals and targets needs active participation of present and future generations, hence education of these tasks is inevitable. The aim of the research is to specify those goals and detailed targets in which renewable energy sources are involved. The latter is just one aspect for bringing the whole complex closer to the adults and youngsters to educate. This topic, however, is characterised by three features that make this aspect appealing: renewable energies are (i) fast developing, (ii) future oriented by saving the environment and (iii) they represent relatively new pieces of knowledge, so contemporary information should not fight with older learning. Before turning to these goals and targets, a reasonable classification of the 17 goals, listed without any systematic order in the UN document, is provided. The presented classification of the goals recommends the following groups: (i) Primary needs of humans (Goals 2, 3, 6 and 7) (ii) Equality between humans (1, 4, 5 and 10), (iii) Efficient, sustainable production (8, 9, 12 and 13), (iv) Landscapes in danger (11, 14 and 15) and (v) Worldwide cooperation (16, 17). From these Goals, No. 7 (affordable and clean energy) and No 13 (climate action) are in full synergy with the aim of extended renewable energy utilisation, but No 2 (zero hunger) might be in contradiction with extensive land use for bio-energy. If consumption of timber for bio-energy continues to be intense than No. 15 (life on land) may also contradict to other goals of sustainable development. Six further targets are identified as related to renewable energies without relatedness of the complete goals. So, we may consider 14 targets belonging to 9 goals to be related to energy sources. The recommended classification of the goals and quotations of the energy-relevant targets are illustrated by some world-wide and Hungarian indicators. Being acquainted with these objectives is useful for all youngsters, presented at their level of knowledge, and it provides a good basis to refresh one’s activity expressed in the environmental education. Keywords: climate change, environmental education, renewable energy, sustainable development.

Climate change and awareness of the need to care for the environment have resulted in a global increase in the interest in renewable energy sources. The European Union (EU) is active in this respect and requires Member States to fulfill specific plans in the transformation of their energy systems. We employed hierarchical cluster analysis in an attempt to distinguish those countries among the new EU Member States that increased their electrical capacity from renewable energy sources to the greatest extent while paying attention to their energy intensity. The analyses were conducted in two scenarios for both 2004 and 2016. The first scenario assumed an analysis of all known renewable energy sources, whereas in the second scenario, only renewable energy sources from wind and solar power plants were included. The division of analyses into these two variants showed the importance of the differences in the energy assessment of individual countries, depending on classification of renewable energy sources. We identified groups of countries where electrical capacity from renewable energy sources increased the most. Conducting analyses using two variants allowed distinguishing countries that based most of their renewable energy on modern renewable energy sources, such as solar and wind power plants. The inclusion of gross domestic product in the analyses allowed us to identify countries with the worst energy efficiency value.

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.
