Brown coal deposits are currently mined in the Konin area, and form the basis for the province's power industry (the Pątnów-Adams-Konin coal-fired power stations account for more than 10% of the national electricity production). The region also has significant quantities of peat deposits; it is calculated that there are ca. 886 thousand hectares of land covered with an average thickness of 1.5 m of peat. An abundance of raw materials used in the production of numerous medicines was recently discovered in the muds of Błażejewo, Oderbank and Mechnacz. In addition, very large deposits of brown coal have been discovered in the vicinity of Kościan, these however are not currently being extracted and probably never will be extracted, due to the expense that would be incurred in adapting the site to build a coal mine and the need to resettle thousands of people.
