The European Commission has adopted the European Green Deal strategy, which aims to achieve climate neutrality in the EU by 2050. To achieve this goal, it is necessary to shift the economy toward the use of green and renewable energy. Critical raw materials (CRMs), Li, Co, REE, Te, Sc and others, are used in renewable energy sources (RES) production. The EU lacks its own CRM deposits, and additionally, the access to already identified deposits is limited, which is making the EU countries search for alternative CRM sources. One such source of CRMs may be mining waste generated on the Indonesian island of Bangka as a result of processing cassiterite-bearing sands. Studies of the mineral composition of the waste using the XRD method reveal rich contents of xenotime (0.79–17.55 wt%), monazite (1.55–21.23 wt%), zircon (1.87–64.35 wt%) and other minerals, carriers of valuable metals, such as Sn, Ti, Nb, Ta. The point mineral chemistry analyses were performed using EPMA. Xenotime is the main carrier of heavy rare earth elements (HREE), especially the “most critical” HREEs: Gd2O3 (1.42–7.16 wt%), Dy2O3 (2.28–11.21 wt%), Er2O3 (2.44–7.85 wt%), and Yb2O3 (1.71–7.10 wt%). Xenotime is characterized by a complex internal structure resulting from metasomatic processes occurring during their formation. In SEM-BSE imaging, they show zonation of internal structure, which is the effect of an HREE, Y, Si and U substitution in the crystal structure. On the other hand, thorite ThSiO4 and uranothorite (Th,U)SiO4 inclusions are present in xenotimes. The ICP-MS/ES studies of tailings reveal very high contents of HREE + Y (up to 7.58 wt%), U (up to 0.11), Th (up to 0.75 wt%) and Sc (132 ppm). A CRM source diversification is part of the strategy to ensure the security of raw materials for countries of the European Union and the green transformation of the continent. Bilateral EU–Indonesia cooperation in the geological exploration and development of primary and secondary sources may contribute to an increase in the supply of HREEs to the global market.

The paper’s main purpose was to identify and present the current situation and changes in energy consumption in agriculture in the European Union (EU) countries. The specific objectives were the determination of the degree of concentration of energy consumption in agriculture in the EU countries, showing the directions of their changes, types of energy used, and changes in this respect, establishing the correlation between energy consumption and changes in the economic and agricultural situation in the EU countries. All member states of the European Union were deliberately selected for research on 31 December 2018 (28 countries). The research period covered the years 2005–2018. The sources of materials were the literature on the subject, and data from Eurostat. Descriptive, tabular, and graphical methods were used to analyze and present materials, dynamics indicators with a stable base, Gini concentration coefficient, concentration analysis using the Lorenz curve, coefficient of variation, Kendall’s tau correlation coefficient, and Spearman’s rank correlation coefficient. A high concentration of energy consumption in agriculture was found in several EU countries, the largest in countries with the largest agricultural sector, i.e., France and Poland. There were practically no changes in the concentration level. Only in the case of renewable energy, a gradual decrease in concentration was visible. More and more countries developed technologies that allow the use of this type of energy. However, the EU countries differed in terms of the structure of the energy sources used. The majority of the basis was liquid fuels, while stable and gaseous fuels were abandoned in favor of electricity and renewable sources—according to which, in the EU countries, the research hypothesis was confirmed: a gradual diversification of energy sources used in agriculture, with a systematic increase in the importance of renewable energy sources. The second research hypothesis was also confirmed, according to which the increase in the consumption of renewable energy in agriculture is closely related to the economy’s parameters. The use of renewable energy is necessary and results from concern for the natural environment. Therefore, economic factors may have a smaller impact.

Purpose The purpose of the paper is to provide estimation results for feasibility of renewable energy source (RES) deployment in Turkey, the Western Balkans and North Africa. From these results, the potential for cooperation in renewables production between the countries and the European Union (EU) is assessed and evaluated, in a mid- (2030) and long-term (up to 2040) perspective. Design/methodology/approach The authors focus on the quantitative assessments undertaken on the extent to which RES cooperation can create mutual benefits, identifying costs and benefits for both sides, but in particular with respect to RES target achievement (2020 and 2030) at EU level. The potentials for RES generation in Turkey, North Africa and the Western Balkans are calculated under different policy pathways, taking into account different levels of economic and non-economic barriers that could occur. Findings Overall, the authors found that increasing RES deployment in the three analysed regions and initiating or intensifying cooperation with EU28 Member States leads to mutual benefits. Concretely, these benefits become apparent in terms of the EU Member States importing renewable energy sources for electricity with a good resource quality and adding on to their targets for RES deployment. At the same time, substantial savings occur for the EU, in turn leading to income and investments in the cooperating regions. Originality/value The assessment underlying this paper is the first of its kind to the authors’ knowledge that opens up the geographical spread in comparison to merely assessing cooperation between Europe and the Middle East and North Africa. Furthermore, the multitude of policy parameters analysed provides detailed and robust insights concerning a broad variety of different possible scenarios.

The article analyses the EU policies of promoting renewable energy sources (RES), including the role of state subsidizing and the change of EU policy in 2013. First EU actions in this area were implemented in late 1990s. In mid 2000s the European Commission developed integrated approach of the encouragement of renewables. Promotion of RES was integrated with other areas of the EU energy policies in the framework of the Climate and Energy Package in 2007. The paper evaluates EU achievements and development of particular types of RES in the EU in 2000s. A comprehensive comparative analysis of the cost of different types of RES and the use of incentive measures in the European Union and EU member states is carried out. The conclusion is made that despite the impressive technological progress the renewable energy, with rare exception, is still uncompetitive with the traditional sources of energy in terms of costs. A large-scale state support was the reason for the rapid development of renewables in the EU. Article investigates distorting effects of RES subsidies on the market price of electricity. Feed-in tariffs, investment grants, quotas and tax benefits were the most widespread forms of direct and indirect RES subsidies in the EU. During the economic crisis, these subsidies have become a heavy burden for the budgets of the EU countries and population. Now the EU is modifying its strategy on RES in order to reduce the volume of subsidies. In 2013 European Council substantially changed the priorities of the EU energy policies: instead of «sustainable energy» it accentuated the need to provide a “competitive energy”. Strategic decision to reform the existing methods of RES subsidizing and to develop an «economically reasonable» support scheme was made. The reduction of subsidies will inevitably lead to a sharp reduction in the rate of growth of renewables and the failure to achieve previously agreed EU targets.

Purpose Following the issuance of the Renewable Energy Directive in 2009, the European Union (EU) is explicitly pushing for member states to cooperate with third countries to meet their EU 2020 targets. So far, no single joint project is planned or in place yet. This paper aims to look at the opportunities for and barriers to possible RE exports from North Africa into the EU through the concept of a SWOT (strengths, weaknesses, opportunities and threats) analysis. Design/methodology/approach Thus, the SWOT for a possible implementation of Article 9 projects are analyzed using expert and stakeholder knowledge. A qualitative assessment was undertaken using data collected through one stakeholder workshop in North Africa, in-depth interviews and a qualitative literature review. The analysis was structured within a three-tier analyzing concept distinguishing between macro, micro and acceptance parameters. Findings From the SWOT analysis, some lessons are drawn, future possible measures are identified and conclusions for policymakers are discussed. The authors find that no easy solutions exist as most parameters can be both a strength and a weakness or a threat and an opportunity at the same time depending on future developments and the specific ideological perspective. Originality/value This paper provides new information and analysis of renewable energy sources projects in North Africa – application of the SWOT method on Article 9 cooperation projects – application of a three-tier analysis to cope with the complexity of the topic – taking into account often neglected socio-political aspects such as public acceptance.

AbstractThe policy of renewable energy sources has gained more importance over recent years. The European Union is facing serious challenges regarding greenhouse gas emissions and energy sustainability, followed by the supply security, import dependence and competitiveness as well as the effective implementation of the internal energy market. The energy policy of the European Union is the most effective response to the new situation the member states of the European Union are facing. The EU energy policy aims to cause a new industrial revolution and the growth of the economic energy efficiency with low emissions of carbon dioxide. In order to achieve this, targets have been set for the future. Among them is the increase in the share of production and consumption of renewable energy in the total energy balance.

The article is devoted to the analysis of the development of environmental diplomacy of the European Union. Today environmental diplomacy has become an important way for states to promote their course of environmental diplomacy, to protect their environmental rights and interests, to promote their own economic and environmental development. The most striking example of the application of green diplomacy on a regional and global scale is the environmental policy implemented by EU member states. Within the EU there is a huge number of environmental programs for the development of renewable energy sources, protection of flora and fauna, as well as combating pollution of water and land resources. To implement its own environmental diplomacy, the EU has adopted a number of important regulations, which are analyzed in the article. The most thorough legal act in the field of environmental diplomacy was Council Directive 85/337 / EEC of 1985 on the assessment of the effects of public and private projects on the environment. This directive reflects the EU’s desire to draw the attention of government agencies and the public to environmental issues and to encourage their collective solution. EU environmental diplomacy is carried out through diplomatic missions, missions, delegations, as well as at the individual level. It involves European politicians and officials who are able to influence international public opinion, employees of foreign ministries and diplomatic missions. The EU also involves third countries as partners to discuss the most pressing environmental issues and their future solutions: climate change, biodiversity conservation, soil depletion, forest and water resources, and renewable energy. Environmental protection is one of the priority areas for European integration. States wishing to join the EU must meet its environmental standards and implement key principles of environmental legislation. It is noted that the EU countries are trying to transfer the economy to clean technologies and diplomatically encourage others to take measures to improve the environmental situation.

Certainly, the renewable energy sector in Poland should be the beneficiary of the European Union enlargement. It results from both the energy policy and EU law. Poland should adopt national law to the EU requirements in the field of renewable energy sources. Polish legislators may rest on other countries' experiences in this subject. We especially should take into consideration Spanish and German measures. Spanish and German mechanisms of support for renewable energy sources at the national level are very interesting solutions. Those measures are intended to help to attain objectives such as meeting the commitments given on climate change, environmentally sustainable security of supply, and promotion of renewable energy sources. The article is an analysis of Spanish and German support systems in view of the modification of Polish law in the field of renewable energy sources.

Energy plays a crucial role in the modern world. The acquisition and consumption of energy is unfortunately associated not only with economic development or the facilitation of everyday life, but also with a negative impact on the environment. To prevent these, measures are being taken which are part of a broad programme referred to as sustainable energy development (SED). A special place among energy consumers is occupied by households, as access to energy is a fundamental factor affecting the quality of life. The aim of this paper is to look at and assess the current situation of the household sector in the EU energy market in the context of SED and to point out similarities and differences between EU countries. The analysis considers factors based on SED indicators: final energy consumption per capita, energy prices offered to households, and the share of renewable energy in household energy consumption. The k-means method was used as a research tool. The results obtained indicate first of all that the EU countries are highly differentiated in terms of the analysed factors. It can be said that these differences result not only from the wealth of a given country, geographical location, or natural possibilities to use renewable energy sources, but mainly from the energy policies implemented in individual countries.

This article is part of the concerns generated by the need to increase the consumption of renewable energy, so that in the European Union (EU) countries, its share in the final energy consumption, to reach 32% by 2030, increases. In the context in which, in the specialized literature, the analysis of renewable energy consumption by activity sectors is approached very little, such an analysis has high utility. The variables of interest are the share of renewable energy in the final energy consumption, and the share of renewable energy sources in the final energy consumption in transport, electricity, and heating and cooling. The study performs a comparative analysis of the evolution of these indicators for the period 2004–2019 for Romania and the EU, an empirical estimate of the evolution of indicators using time regression and autoregressive models, a forecast of the share of renewable energy consumption in the final energy consumption and by the main sectors (transport, electricity, and heating and cooling) for the 2030 horizon, providing appropriate scenarios for achieving the EU established goals, as well as an analysis of the interdependence between the indicators. Through the results obtained, the paper can contribute to improving the framework for the sustainable development of energy consumption.
