This YouTube channel is the European Union official video channel where it publicises its work.  There are many video clips covering all aspects of this, so some do not cover economics.  However, there are some good educational clips on subjects like central banking (Economia and Inflation Island), or financial services,  which look at economic principles relating to the EU.  These may form teaching materials for classroom debate.
