This in turn seems to have contributed to greater overall support for nuclear power generation. Figure 4.13 illustrates the shares of positive and negative responses to the proposition “the use of nuclear energy enables European countries to diversify their energy sources” (on the vertical axis), and the share of support for nuclear energy (on the horizontal axis), the correlation is examined for nuclear and non-nuclear countries. The correlation coefficients are 0.87 for 2005 and of 0.78 for 2008. Relatively high correlation coefficients suggest that the role of nuclear power in the diversification of energy sources is one of the key drivers behind increasing public support for nuclear generation.
