Abstract

In this note the present and future concentration of the European gas import is shown with the help of the Herfindahl Hirschmann Index. This may be considered as one of the aspects of the European energy dependency. A high HHI implies that for its gas supply the EU depends on relatively few large suppliers. A low one indicates that the supply is coming from a large number of relatively small suppliers. Generally speaking a large number of small suppliers means that these suppliers have less power to influence EU policies than a small number of large suppliers. Consequently a high HHI is an indication of more potential external influence on EU-policies.
