The Polish Wind Energy Association (PWEA) is Poland’s largest organization promoting alternative energy sources, mainly onshore and offshore wind power. It is actively involved in consultations on strategic documents and acts of legislation related to the market of renewable energy sources, alternative fuels, and the energy transition. By working together with decision-makers at the EU, national, and local government levels, it aligns various interests to promote Poland’s sustainable development. It organizes events bringing together representatives of the sector and decision-makers, including the annual PWEA Conference – the largest such event in Central and Eastern Europe ( http://konferencjapsew.pl/en/) devoted to prospects for the development of onshore and offshore wind energy in Poland. The Association initiated the establishment of the RE-Source Poland Hub Foundation ( http://resourcepoland.pl/en/), which shows businesses how they can become part of the trend towards the green transition and sustainable development. It promotes pro-environmental attitudes and knowledge of the environmental, economic, and social benefits of wind energy in the media, on social media (such as https://www.facebook.com/psew.pwea and https://twitter.com/PSEW_PWEA), and during the “Summer with the Wind” family summer picnics (Lato z wiatrem) held at the Baltic Sea.
