The article compares the management of energy resources in Poland and Ukraine over the period 2000–2017. The analysis took changes in the volume of coal, oil and natural gas resources into consideration. The indicators of supplies of these fuels for Poland and Ukraine have additionally been compared with selected EU countries. In order to assess energy security of Poland and Ukraine, the changes in the primary energy consumption have been analyzed in general in first order, then the possibilities of meeting the demand for natural gas, coal and oil have been determined based on the domestic extraction of individual energy resources. Such a comparison indicates the dominant role of coal in Poland while the extraction of oil and natural gas meets the domestic demand to a greater extent in Ukraine. Over the period 2000-2017, trends in primary energy consumption were different; a 17% increase was noted in Poland, while a nearly 40% decline was noted in Ukraine. The main factors responsible for radical changes in fuel and energy management in Ukraine have been identified: military operations in the east of the country and the annexation of Crimea, demographic changes. These events had a negative impact especially on the volume of hard coal mining in Ukraine; the significant increase in imports from 5.36 to 19.14 million tons in 2011-2017 was necessary for balancing. The balance of foreign exchange for electricity was also compared. Over the past years, this comparison has been favorable for Ukraine, where the dominance of electricity exports over imports is noticeable, which generated revenues of over USD 200 million in 2017.
The paper analyzed the natural gas sector in Ukraine for the period 2000 to 2018. This sector was affected by external factors, such as the crisis which began in late 2008/2009, as well as internal factors, including the situation in Ukraine after 2013 (the Annexation of Crimea). A comparative analysis was also conducted of the natural gas sector in European Union countries and Ukraine – compared the specificity of natural gas consumption in 2018. The analysis (I) examined the demand for natural gas in Ukraine between 2000 and 2018; (II) described changes in sources to cover Ukraine’s gas needs with a particular emphasis on its own production; (III) pointed to the fundamental changes that have occurred in the natural gas supply routes to the Ukrainian sector in recent years; (IV) stressed the growing role of own production in balancing Ukraine’s gas needs; (V) described the role of Ukraine as a transit country for Russian gas to be delivered to EU countries (in recent years, the volume of natural gas transmitted via the Ukrainian transmission system has been around 90 bcm annually); and (VI) looked at the structure of natural gas consumption in the Ukrainian gas sector and how it has changed in recent years. Unlike EU countries, the growing role of own production in balancing Ukraine’s natural gas needs was emphasized, which is consistent with the strategy of the Ukrainian government. Also, attention was drawn to the threats that may significantly reduce the role of Ukraine as an important transit country. The paper also puts forward the most important parameters concerning the underground natural gas storage facilities in Ukraine which is one of the largest in Europe.
The main objective of the article is to assess the changes in carbon dioxide emissions in residential sector caused by the implementation of the plans contained in the Air Protection Programs, anti-smog resolutions adopted in 9 voivodeships and the nationwide “Clean Air” program. The reduction of emissions of pollutants which directly affecting air quality and human health, i.e. particulate matter and benz(a)pyrene, which residential sector is the main source, can also affect the amount of emitted of carbon dioxide. To determine the changes in carbon dioxide emissions in the residential sector, emissions of CO2 in base year of 2017 from various energy carriers were determined, plans for reducing of low-stack emission were reviewed and the future structure of energy carriers used in households was estimated. The processes of increasing the efficiency of energy use through both the replacement of boilers and thermomodernization were also taken into account. The obtained results show that the highest CO2 emission reduction of 6% is achieved in case of “Clean Air” program. In frame of this program in 3.5 million of single-family houses a heating system replacement and thermomodernization is planned. Implementation of plans included on Air Protection Programs and anti-smog resolutions can lead to a relatively small (approx. 1%) reduction of CO2 compared to base year 2017. The detailed results of future fuel consumption and CO2 emission for individual voivodeships and for the whole of Poland was presented.
Polska od lat zmaga się ze złą jakością powietrza, co bezpośrednio przekłada się na zdrowie ludzkie. Badania wskazują, że największy wpływ na przekraczanie poziomów dopuszczalnych i docelowych stężeń zanieczyszczeń, szczególnie pyłów oraz bezno(a)pirenu, ma niska emisja, w szczególności z sektora gospodarstw domowych. Powodem takiego stanu jest spalanie złej jakości paliwa w starych, mało efektywnych i wysokoemisyjnych paleniskach. Mając na uwadze powyższe zagrożenia, idąc śladem Krakowa i Małopolski, kolejne województwa, miasta i gminy wprowadzają lub rozważają wprowadzenie ograniczenia spalania paliw stałych na swoim terenie oraz całkowitą likwidację kotłów na paliwa stałe niespełniające wymogów ekoprojektu lub ewentualnie normy 5 klasy emisji spalin.
Określenie wielkości emitowanych zanieczyszczeń do atmosfery ma kluczowe znaczenie w przypadku podejmowania wysiłków i określania działań zmierzających do poprawy jakości powietrza. W Polsce ruszyły ambitne programy zarówno na poziomie rządowym, jak i regionalnym, które mają na celu wymianę kotłów i pieców w kilku milionach domów. Na przykład szacuje się, że prawie pół miliona kotłów należy wymienić w ramach realizacji uchwały antysmogowej w województwie małopolskim. W artykule zostały przedstawione opracowane współczynniki emisji zanieczyszczeń mających bezpośredni wpływ na lokalną jakość powietrza tj.: współczynniki emisji pyłów, bezno(a)pirenu, tlenków siarki i azotu, tlenku węgla. Zostały wskazane zakresy stosowanych i prezentowanych współczynników emisji dla różnych technologii oraz różnych paliw. Wskazane zostały również standardy emisji obowiązujące dla nowych kotłów oraz ilości zużywanych paliw w gospodarstwach domowych w Polsce.
Przedstawiono możliwe zmiany wielkości emisji w przypadku likwidacji starych kotłów i używania nowoczesnych urządzeń do spalania biomasy oraz węgla w gospodarstwach domowych oraz przeprowadzenia termomodernizacji.
