In this paper, we analyze the energy security situation of the G7 countries using a statistical risk indicator and empirical energy data for the years 1978 through 2010. We find that Germany’s energy supply risk has risen substantially since the oil price crises of the 1970s, whereas France has managed to reduce its risk dramatically, most notably through the deployment of nuclear power plants. As a result of the nuclear phase-out decision of 2011, Germany’s supply risk can be expected to rise further and to approach the level of Italy. Due to its resource poverty, Italy has by far the highest energy supply risk among G7 countries.enDiscussion Paper / SFB 823;28/2012energy supply risk indicatorHERFINDAHL Index310330620Measuring long-term energy supply risksA G7 rankingworking paper
