Poland is one of the largest coal-mining countries in Europe. However, more and more energy comes from renewable resources. That is why PGE, the largest national energy group in Poland, decided to raise public awareness of eco energy. To show how eco energy works, we used water and only water to create an impressive image of local nature by removing dirt from the surface of the Solina Dam. We wanted to pay tribute to the local nature and present the symbols of Bieszczady region.
