Jerozolimskie 63, 00-697 Warsaw, Poland; [email protected] * Correspondence: [email protected] Received: 14 June 2020; Accepted: 14 August 2020; Published: 18 August 2020 Abstract: The aim of this paper is to present the state of development of renewable energy sources (RES) in Poland in accordance with the obligations of European Union energy policy. The EU Member States are obliged to adopt different support mechanisms for the development of renewable energy sources, and in consequence to achieve their Directive’s targets. Poland, being a Member State of the EU since 2004, has accepted a target of a 15% share of energy generated from renewable energy sources in final energy consumption, including 19.3% from renewable electricity until 2020. Due to the difficulties with target achievement, the authors found it reasonable to analyze the challenge of RES development in Poland. The article presents energy policy in the EU, as well as the review of measures implemented for renewable energy development. The current state of and perspectives on using renewable energy sources in Poland and in the EU are also depicted. In the article, the authors analyze the relation between reference prices at dedicated RES auctions in Poland and the levelized cost of electricity (LCOE). The paper also provides a description of the renewable energy sources’ development in three areas: electricity, heat and transport biofuels. Its main content, though, refers to the generation of electricity from renewable energy sources. Keywords: renewable energy sources; electricity generation; energy policy; electricity market; Poland; European Union 1. Introduction Renewable energy sources (RES) are currently one of the pillars of energy development worldwide [1]. Their utilization contributes to the process of industry de-carbonization, thanks to much smaller amounts of emitted carbon dioxide (CO2)[2]. However, it has to be remembered that their widespread use also raises many challenges for the electricity sector [3]. According to International Renewable Energy Agency (IRENA), the total installed capacity of renewable energy sources worldwide in 2019 was 2537 GW [4]. Solar photovoltaics (PV) and wind energy are mainstream options in the power sector, with an increasing number of countries generating more than 20% of their electricity with solar PV and wind. Almost half of this installed capacity—1118.969 GW—is located in Asia, including 758.626 GW in China. Europe has 573.266 GW of renewable capacity installed. The International Energy Agency (IEA) predicts the further increase in the new capacity of renewable sources to be approximately 160 GW in 2020, and 190 GW in 2021 [5]. As mentioned previously, Europe is investing heavily in renewable energy sources. This is related to the strategy that the European Union has adopted in the battle against excessive CO2 emissions, at the same time boosting the transition to a low-carbon economy [6,7]. This has also been confirmed Energies 2020, 13, 4261; doi:10.3390/en13164261 www.mdpi.com/journal/energies Energies 2020, 13, 4261 2 of 31 by documents endorsed by the EU Parliament. The transition towards energy generation from low or zero emission sources in the EU was implemented in 1997 with the adoption of the White Paper [8]. Its introduction was aimed at impeding the import of coal, often of low quality, from outside the EU, and also at the introduction of the widely understood de-carbonization of the energy sector. Since 1997, in the scope of the promotion of renewable energy sources, the emphasis shifted from indicative targets (to be achieved in 2010) to legal targets. The aim is to define the basic legal framework for the transition from 2020’s into 2030’s perspectives, including a complex internal energy market mechanism [9]. Meanwhile, due to the dynamic development of renewable energy sources, new or revised support mechanisms for the construction of RES sources have been established. Before 2010, the development of renewable energy was regulated by a legal framework which set indicative targets for each Member State. Directive 2001/77/EC of 27 September 2001 on the promotion of electricity produced from renewable energy sources in the internal electricity market [10] set national indicative targets to be achieved by the EU for the share of renewable energy in electricity production at 21% by 2010. Directive 2003/30/EC of 8 May 2003, on the promotion of the use of biofuels or other renewable fuels [11], set national indicative targets to be achieved by the EU for the share of renewable energy replacing petrol and diesel in transport at 5.75% by 2010. Due to the rather small impact of the introduction of Directive 2003/30/EC, as well as the lack of commitment of Member States to the achievement of the targets for renewable energy sources, at the end of the first decade of the 21st century, the European Commission started working on a new Directive which defined the next step of the development of renewable energy sources in 2010–2020. It introduced provisions setting the mandatory targets and commitments of Member States. The directive was supported by the European Commission, EU Council and European Parliament [12]. In 2009, a new Directive (2009/28/EU) on the promotion of energy production from renewable energy sources was introduced [13]. Its provisions brought about a complete change of approach in the RES sector and in the functioning of the energy market [14]. The introduction of Directive 2009/28/EU unified the regulations and additionally introduced provisions concerning the production of heating and cooling from RES. Therefore, the new regulations allow the covering of all areas for RES development, electricity, heating and cooling and biofuels. Directive 2009/28/EU defines common objectives for the aforementioned areas, while offering the Member States flexibility in the implementation of individual solutions. However, it should be mentioned that the obligation of 10% use of biofuels in the transport sector was imposed.

Table 1 presents targets and their realization in Member States. The EU as whole was, in 2018, on track to achieve the 2020 target, and countries like Bulgaria, Czech Republic, Denmark, Estonia, Greece, Croatia, Italy, Cyprus, Latvia, Lithuania, Finland and Sweden had achieved their targets before the expected date. In the following part of this article, the matter of RES target implementation by Poland is addressed in detail. Table 1. Share of renewable energy in final energy consumption (%) [16,17].

Preliminary data shows that some Member States had already successfully met their targets ahead of schedule, while some may have difficulties meeting them before the end of 2020. The current situation of the COVID-19 pandemic affects the electricity market. With the introduction of the pandemic regime, in many power systems electricity consumption decreased. In March–April 2020, when the COVID virus has started to spread in the European Union, demand for electricity decreased by about 10–30%.

    Varying the Energy Mix in the EU-28 and in Poland As a Step Towards Sustainable Development

    energies Article Varying the Energy Mix in the EU-28 and in Poland as a Step towards Sustainable Development Wiktoria Sobczyk 1 and Eugeniusz Jacek Sobczyk 2,* 1 Faculty of Mining and Geoengineering, AGH University of Science and Technology, 30-059 Krakow, Poland; [email protected] 2 Mineral Energy and Economy Research Institute of the Polish Academy of Sciences, 31-261 Krakow, Poland * Correspondence: [email protected] Abstract: The demand for clean energy is a key global issue requiring global ideas to be implemented through local action. This is particularly important in Poland’s energy transition, since the country produces energy mainly from conventional sources, i.e., coal, gas, and crude oil. Adverse climate change caused by high emissions of the economy based on the combustion of hydrocarbons as well as the growing public awareness have made it necessary to look for new environmentally friendly energy sources. The aim of the paper is to demonstrate that the use of alternative energy sources, biomass in particular, is compatible with sustainable development policy. Eight indicators for the EU-28 and for Poland were analysed in order to verify the progress in modifying the energy mix between 2010 and 2018 in the context of implementing Sustainable Development Goals (SDGs). The analysis showed that both in the EU-28 and in Poland, the aggregated indicator taking into account the positive and negative change in the values of individual indicators improved between 2010 and 2018. In the EU-28, this indicator is higher (180.1) than in Poland (152.3). The lower value for Poland is mainly due to the fact that the main source of energy in Poland remains hard coal Citation: Sobczyk, W.; Sobczyk, E.J.

    Energy Innovation in Poland: Frameworks, Programmes and Strategies

    Policy Paper Energy Innovation in Poland: Frameworks, Programmes and Strategies December 2017 Introduction Innovation is one of the key concepts of contemporary economies. Energy is one of the sectors where efficiency and new solutions are sought for with great interest, but at the same time, where path dependent processes and various technological lock-ins often inhibit swift change. Despite various obstacles, energy innovation is a global trend today and the European Union, as well as its particular member states, are actively shaping innovation strategies at various levels: sectorial, cross-sectorial or inside companies. Globally, the 3Ds are setting a framework for innovation in energy: decarbonisation, decentralisation and digitalisation. Certainly, an important global document guiding innovation in Energy towards decarbonisation is the Paris Agreement of 2016. At the EU level, decarbonisation, and more generally, climate change policies are also the main trends giving direction for innovation in national power sectors. The EU Climate Change and Energy Package of 2009, was the first main package of directives that gave a clear signal for renewable energy development, and at that time, also to work towards the deployment of carbon capture and storage at an industrial scale. And even though CCS is still rather an expensive option for the future than an economic option for industries, EU regulations have given many positive stimuli in the sector of energy efficiency and renewable energy (including photovoltaics). These areas may count on financial support from banks and investment funds. Also, the Europe 2020 strategy gave an impulse for various innovations in European economies, among which one can list smart grid technologies.

Grunwaldzka 53, 50-357 Wroc³aw, Poland Morphological diversity of chernozemic soils in south-western Poland Abstract: Diverse chernozemic soils featured by thick mollic horizon, rich in humus, dark-coloured, structural, and saturated with base cations are relatively common in the loess-belt of SW Poland. It is postulated, that most of these soils may have similar initial (chernozemic) history of thick humus horizon, related to climate conditions and vegetation in the Late Pleistocene and the Neolithic periods. However, these soils exist on various bedrocks and under different moisture conditions that led to the develop- ment accompanying features and variable classification of soils, both in Polish and international soil classifications. The aim of the paper is to presents the most important variants of loess-derived chernozemic soils of SW Poland, in relation to local conditions, which influenced soil transformation and present spatial diversification. 'Typical' chernozems (WRB: Calcic Chernozems), which have a mollic horizon and secondary carbonates, but are free of strong redoximorphic features, are rather uncommon in the region. Whereas, the black earths (WRB: Gleyic/Stagnic Chernozems/Phaeozems), featured by the presence of mollic horizon and strong gleyic or stagnic properties in the middle and bottom parts of the profiles, are predominant loess-derived chernozemic soils in SW Poland. Their most specific forms, developed on the clayey bedrock, are black earths with a vertic horizon (WRB: Vertic Stagnic Phaeozems).

Box 100 A-1400 Vienna, Austria COMPARATIVE STUDIES OF ENERGY SUPPLY OPTIONS IN POLAND FOR 1997–2020 IAEA, VIENNA, 2002 IAEA-TECDOC-1304 ISBN 92–0–112602–6 ISSN 1011–4289 © IAEA, 2002 Printed by the IAEA in Austria August 2002 FOREWORD Poland depends heavily on coal to satisfy national demands for electricity. Currently, over 90% of electricity generation is produced by coal fired power plants. Because of the large dependence on coal and environmental impacts of large-scale coal combustion the country looks for a more diversified energy mix. As ways of diversification, Poland is considering the expanded role of natural gas and, potentially, nuclear power in the future energy mix. This publication describes the analysis of several diversification options for the Polish energy sector conducted by a national team in the framework of an IAEA Technical Co- operation project implemented in 1999–2000.
