Sustainable Energy Policy

Often when people think of policy for long-term sustainability they think of energy supply and not energy demand. What comes to mind often are new sources of supply on the very edge of technology, such as shale gas and deep-sea oil resources; or it may be renewable energy sources, such as hydro, wind, solar, geothermal and biofuels. But if people focus exclusively or excessively on supply, they are overlooking the demand side. How much energy must we produce in order to meet our human and economic needs? What assumptions are we making about future energy demand? In regard to a particular energy project going through an environmental impact assessment process, how do we evaluate whether the project is necessary?

Evaluating Methods

Der Ausbau erneuerbarer Energien in Deutschland konfrontiert die deutsche Industrie mit einem volatilen Energieangebot. Eine Möglichkeit hierauf zu reagieren ist, den Energiebedarf flexibel dem Angebot anzupassen und niedrige Strompreise zu nutzen. Ergänzend zu den bestehenden Bewertungsmethoden wird eine Vorgehensweise vorgestellt, die eine Beurteilung des Potentials an Energieflexibilität einzelner Anlagen erlaubt. Ziel ist es, anhand einer Voruntersuchung entscheiden zu können, ob diese Anlagen einer intensiven Bewertung unterzogen werden sollten.   With the expanded use of renewable energy sources, German industry will be faced with a volatile energy supply. One way to react is to adapt energy demand to energy availability. In addition to existing evaluating methods, an approach to review the potential energy flexibility of production systems is presented. The objective is to be able to decide, if a detailed evaluation of the energy flexibility of a machine is useful.

Energy Service

The potential of renewable energy resources has been investigated and its is shown that they can in fact fulfill most of the world’s energy demand. In this study renewable energy sources such as biomass, solar, wind, geothermal and hydropower are studied and provided with sustainable energy services, based on the available natural resources. In the past three decades wind and solar power system have developed rapidly in sales, while there was a decline in their capital cost and costs of electricity generated. This study shows that the transition to renewable –based energy systems are increasing and continues to improve their performance characteristic. The enhancement and utilization of renewable energy sources can increase diversity in energy supply market, help to secure long term supportable energy supplies, keeping the environment clean by reducing local and global atmospheric emissions, establish marvelous options too encounter specific energy service needs by helping to create new job opportunities especially in developing countries.

Energy Justice

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.

В статье рассмотрено современное состояние энергоснабжения и перспективы развития альтернативных источников энергии на территории Крайнего Севера. Отмечено, что несмотря на острую потребность во внедрении возобновляемых источников энергии, установленные мощности всех ветряных и солнечных электростанций в регионе не превышают 7-8 МВт. Также в работе рассчитаны технический и экономический потенциал ветровой энергии региона, на основании которых подобрана наиболее эффективная установка. The article discusses the current state of energy supply and the prospects for the development of alternative energy sources in the Far North. It is noted that despite the urgent need for the introduction of renewable energy sources, the installed capacities of all wind and solar power plants in the region do not exceed 7-8 MW. Also, the technical and economic potential of the region’s wind energy was calculated based on which the most efficient installation was selected.

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.

The Europe 2020 Strategy was proposed with a long-term vision to ensure prosperity, development, and competitiveness for the member countries. This strategy is divided into three main areas named “growth”. One of these is sustainable growth. This is an area of sustainability, where the partial targets are referred to as the “20-20-20 approach”, and includes a reduction of greenhouse gas emissions, an increase in energy efficiency, and the sharing of renewable energy sources. However, questions arise, including: How do member states meet these targets? Which countries are leaders in this area? According to these stated questions, the aim of this article is to assess how EU countries are meeting the set targets for sustainable growth resulting from the Europe 2020 strategy and to identify the countries with the best results in this area. We looked for answers to these questions in the analysis of sustainable indicators, which were transformed into a synthetic measure for comparability of the resulting values. Finally, we identified the Baltic states, Nordic countries (European Union members), Romania, and Croatia as the best countries in fulfilling the sustainable growth aims. As sustainable development and resource efficiency are crucial areas for the future, it is important to consider these issues.
