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.

In this study we aimed to determine the extent to which changes in the share of renewable energy sources, their structural complex, and the level of energy security in Eastern Europe, Caucasus and Central Asia (EECCA) countries in the medium- and long-term are interconnected. The study was performed through modeling and determination of the structural characteristics of energy security in the countries. The methodology of the approach to modeling was based on solving the problem of nonlinear optimization by selecting a certain scenario. For the study, the data of EECCA countries were used. The ability of EECCA countries to benefit from long-term indirect and induced advantages of the transformation period depends on the extent to which their domestic supply chains facilitate the deployment of energy transformation and induced economic activity. This study provides an opportunity to assess the degree of influence of renewable energy sources on the level of energy security of countries in the context of energy resource diversification. The high degree of influence of renewable energy sources on energy security in the EECCA countries has been proven in the implementation of the developed scenarios for its increase. Energy security is growing. At the same time, its level depends not only on an increase in the share of renewable sources but also on the structure of energy resources complex of countries, and the development of various renewable energy sources. Therefore, today the EECCA countries are forced not only to increase the share of renewable energy sources but also to attach strategic importance to the structural content of their energy complex.

Although Indonesia’s electrification ratio reached 99.2% in 2020, it has shown stagnating electrification since 2018. This is because most of the remaining areas that need to be electrified are remote and have unique characteristics that hamper implementation of microgrids for providing energy access. Furthermore, not only the deployment but also the long-term sustainability of microgrids is crucial for ensuring continuity of energy access. This paper aims to investigate the scaling and sustainability challenges of remote microgrid development in Indonesia by analyzing microgrids in the Maluku and North Maluku provinces. This study is a two-part publication; the first part focuses on identifying challenges in Indonesia’s remote microgrid development, while the second part focuses on potential technology solutions. In the first part, an assessment of energy access within a multi-tier framework was conducted, which was then analyzed using a multi-dimensional (institutional, social, technical, economic, environmental, and policy) approach adapted from the literature. The framework was expanded by mapping the challenges onto specific phases of the microgrid development, which is intended to be helpful for the parties involved in specific phases. It is shown that the challenges related to unclear land status, lack of social engagement, preliminary survey, technical and practical knowledge, and O&M procedures—especially for remote microgrids with renewable energy sources—are the most prominent issues. Additionally, issues caused by electrical events and environmental conditions such as relatively humid and high-temperatures, and uncontrolled vegetation, rodents, insects, and lizards are often found. Furthermore, a high-level technological outlook to address some of these issues is presented.

The paper presents technical and economic data on the development of photovoltaic electricity in Bulgaria over the last 10 years. The mix of different types of conventional and renewable energy sources in the country's electricity system is shown. The changes in the installed photovoltaic capacities and the price of electricity generated by them for the studied period are shown in tabular and graphical form. The number of photovoltaic power plants and their distribution by groups of individual powers are given. Brief technical and economic data for some of the largest photovoltaic power plants in Bulgaria are provided. Data analysis shows a short period of rapid development of highcapacity photovoltaic power plants construction after the introduction of high feed-in tariff for the purchase of photovoltaic electricity, as well as the influence of the installed photovoltaic capacities on the market change of the feed-in tariff over time. Feed-in tariff cost decreases remarkably with the increase of the installed photovoltaic capacity and even shows removal tendency for larger-capacity photovoltaic power plants. Examples of the economic profitability of grid-connected and autonomous photovoltaic systems in Bulgaria are given. The analysis and conclusions of the paper could be useful in determining new government policies and setting new market conditions to promote the development of renewable energy sources in Bulgaria and other countries.

The article deals with the key aspects of the problem of determining the “carbon footprint” of industrial production. Rapidly increasing greenhouse gas emission within the past two centuries can cause irreversible changes in the Earth’s climate. Various manufacturing industries including “production and consumption of energy” create more than half of the “Earth’s carbon footprint”. The authors present a brief analytical overview of the “carbon footprint” problem in the context of solving a significant issue of global warming. They suggest references to current research and publications of Italian, Chinese and Spanish scientists. For example, Italian researchers proved that social innovations as well as transition to low-carbon technologies can be of good effect in reducing the “carbon footprint”. Chinese researchers (by analyzing 45-year-long data on the quantity of developed natural resources, energy consumption and population growth, “carbon footprint” and carbon dioxide emissions in the USA) proved that in the long-term perspective consumption of natural resources and renewable energy sources can improve the quality of the environment while population growth and consumption of non-renewable energy sources can contribute to its deterioration. Spanish researchers explored the connection between the “carbon footprint” and national peculiarities of people’s life. They listed the basic features of current energy transformation of the global economy (towards increasing the volume of renewable energy sources). The authors considered basic methods of regulating the “carbon footprint” of industrial production: by means of legal prohibition or improvement of pricing mechanism. They introduce the “Strategy of long-term development of Russia with low level of greenhouse gases till 2050”. The article contains information on reporting of greenhouse gas emissions in Russia.

Towards the end of the previous century, the humanity understood very clearly two facts – first, the World supplies of fossil fuels (coal, oil, gas, uranium) are limited, and, second, industrial development and classical generation of electrical energy seriously endanger the environment. Renewable energy sources (sun energy, wind energy, bio fuels, etc.) are based on the use of natural fluxes of energy (Masters,2004). That is why they are considered to be inexhaustible. In specific cases of implementations, for example in lighting, a direct generation of electrical energy using photovoltaics is outlined as a long-term one.

Power is a significant cause of economic growth and crucial to the sustainability of the economy. Energy consumption is an indicator of a nation's economic growth. Economic growth is focused, among other aspects, on the long-term acquisition of affordable, existing resources, and their use does not pollute the environment. Industrialization serves economic growth and consumes energy. In 2018, 68% of total capital power was consumed by largest energy-intensive areas. When fossil fuel is the primary source of energy, energy consumption is positively correlated with ecosystem cleanliness. Fossil fuels account for more than 70% of the decent energy expectations of India and other economies. In this chapter, problems related to non-renewable energy sources are discussed, and emphasis is given to use more renewable sources.
