We would thus expect that the way they analyse the role played by nuclear energy in improving the security of electricity generation is directly or indirectly based on simple, but also perhaps incomplete or biased, indicators that need to be elucidated in order to understand the public attitude towards nuclear energy in ensuring security of supply. They also seem to be fairly knowledgeable of the energy dependence rate of their country. The 2007 Eurobarometer highlights the fact that there are some false beliefs concerning the energy dependency of the European Union. The import ratio for the countries of the OECD Pacific and Europe remains higher than the other regions in terms of import dependency (around 50% by 2007).
