This paper is an attempt to forecast the production, consumption, and net exports of energy resources used as primary energy sources in Poland. Due to the fact that a new energy policy of Poland is under development, the authors relied on the available domestic and foreign documents, the most important of which include the Energy Policy of Poland until 2030, adopted in 2009, and the Forecast of fuel and energy demand until 2050 developed by the Polish National Energy Conservation Agency (KAPE). A draft of the Polish Energy Policy until 2050, together with the most important prognostic analyses used during its development, was also taken into account. The article criticized the forecast of the Polish National Energy Conservation Agency for numerous errors, including not taking into account decreasing energy prices in world markets, ignoring the possible increases in prices of CO2 emission allowances in the European Union, or setting too low renewable energy target for Poland. The authors of the paper are also sceptical about the possibility of launching the first nuclear power plant in Poland in the middle of the third decade of the current century. The forecasts for production, consumption and net exports of bituminous coal and lignite, crude oil, and natural gas in Poland in the perspective of 2040 are presented in the following sections of the article. Special attention has been paid to the projected decrease in the level of coal mining in Poland, especially in the case of bituminous coal, which will increase the import of this raw material to Poland. In the case of natural gas, it is planned to increase the output to 8.5 billion cubic meters in 2040. However, in the coming years Gazprom will continue to be the main supplier of natural gas to Poland, while the demand will be supplemented by the LNG terminal in Świnoujście. From the point of view of energy security, the situation is even more complicated when it comes to the supply of crude oil to Poland. Until 2015, as much as 88% of domestic demand for oil was covered by supplies from Russia (REBCO oil) (the Polish Oil Industry and Trade Organisation; POPIHN 2017). In 2016, this share decreased significantly to 81% despite the contracts with Russian companies; currently, a quarter of the raw material delivered to Grupa LOTOS S.A. is shipped from the Gulf countries. In the case of PKN ORLEN, the share of alternative suppliers against supplies from the east is 12% (POPIHN 2017).
