Energetyka – Społeczeństwo – Polityka

2018

nr 2(8)

88--103

The strategy of Polish energy sector should assume systematic change of the roles of individual energy generation sources. We observe the increasing role of the distributed sources of energy. The conventional coal based energy sources should, under Polish conditions, gradually assume the role of a guarantor of electricity supply. In order to implement such this type of strategy, it is necessary to create a fundamental expertise, that could serve as an Energy Constitution. It could be the basic document for all the strategic changes occurring in the Polish energy system.

One of the most important dilemmas faced by the European Union is the decision on acceptable scale of using fossil fuels – in particular coal, in covering the demand for energy in member states. Currently, there are numerous discussions concerning the restriction of the use of this highly emissive energy carrier by the EU countries, which, as a result, is to reduce air pollution on a global scale. The article presents the use of energy carriers in traditionally coal based regions and forecasts regarding the economics of new investment in coal fired power plants against investment in renewable energy. Comparison of levelised cost of electricity from coal and solar (PV) energy and it’s impact of electivity prices in Poland up to 2040 was done. The conducted analyzes indicate that a hypothetical PV investment alternative could reduce generation costs by 1.5-2% in the long term.
