The International Youth Conference on Energy (IYCE) had three successful previous editions in 2007 and 2009 in Hungary and 2011 in Leiria, Portugal, organized by the Student Association of Energy (SAE), providing a good opportunity for young experts working in different fields of energy- and power engineering to present their work in an international forum and make contacts for their future. The fourth edition of this conference will take place in Siófok, Hungary, on the southern shore of Lake Balaton, the largest lake in Central Europe.
