I think a mixed approach is necessary, when you consider the potential economic damage of sea level rise alone to the EU, any investment in energy production should be tailored towards technologies that can be implemented within a short timeframe.

While I think investment in Nuclear power is critical, I feel that the potential for renewables to rapidly become more productive (pv, geothermal, wave, tide). A mixed approach is best, but the bottom line, we need a big rise in energy R+D funding.
