摘要:Economic and environmental aspects of generating energy from renewable sources in various forms: thermal, electric and mechanical have been presented in this article. Utilization of those resources and their promotion has been imposed on us by the climate convention but substantial level of pollution in large cities of our country contributed to that as well. RES share in the production of electricity and heating in Poland is regulated centrally by the directive of Minister of Economy. RES utilization is gradually becoming more rational in our country. It levels the prices of biomass for energy sector which has a visible impact on the level of round wood prices in Poland.
