62 Energy from renewable sources in 2012, Central Statistical Office, Warsaw 2013. solutions combining the development of renewable energy sources with the development and modernization of the power grid. Standardizing the interpretation of regulations and modifying the RES support system towards greater grid development would also contribute to faster commissioning of new RES. The development of renewable energy in Poland requires measures to promote renewable energy in Poland (action 31), based on the Polish Energy Policy, the National Renewable Energy Action Plan (NREAP), as well as periodic reports on progress in promoting and using energy from renewable sources in Poland (prepared pursuant to Article 22 of Directive 2009/28 / EC). The aim of the program will be to work out specific actions ensuring the implementation of the indicative development path of individual RES technologies specified in the NREAP, and as a result achieving at least 15% share of energy from renewable sources in gross final energy consumption by 2020. The program should contain solutions covering economic, social and environmental issues, so as to ensure the sustainable development of this sector of the economy. Considering the national potential of renewable energy sources, biomass may play a special role. For energy purposes, biomass from by-products, residues and waste from agriculture and agri-food processing should be used in the first place. These raw materials should be used locally in distributed generation units.
