The correlation coefficient between the share of positive responses to this proposition and support for nuclear energy is even higher than in the case of energy source diversification; it is of 0.91 in 2005 and 0.86 in 2008. Most nuclear countries (with the exception of Estonia) can be found in the upper right-hand square indicating both high degree of awareness of the GHG avoidance advantage of nuclear power and high degree of support for nuclear generation. Importantly, one half of non-nuclear countries in Europe are found in the upper right-hand square that can be characterised as a section of improved public acceptance with improved knowledge about the strengths of nuclear energy.
