The South Caucasus is often depicted as the main doorway to the energy rich Caspian region in the energy security narratives of the European Union and of other Western actors in the region. But what are the views from the South Caucasus countries Armenia, Azerbaijan and Georgia concerning their own energy security? This CASCADE working paper seeks to shed light on energy security notions from South Caucasus governments and energy companies, as well as of citizens and consumers. It finds that there are significant differences in the perceptions of the different actors in the energy sector within each South Caucasus country that could lead to political conflicts over energy security strategies.
