Abstract
The security of energy supply has again become a similarly hot topic as it
was during the oil crises in the 1970s, not least due to the recent historical oil price
peaks. 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.
