It's interesting to see how the French government are looking to resolve the issue of energy security. The government are buying the remaining 16% of EDF that the don't already own and are renationalising the sector. It's how they are keeping energy prices low, relative to the UK, but does this represent a good use of government money - to be effectively subsidising the sector. 

And are there other factors about private sector ownership that make keeping the electricity sector in private hands a more efficient decision? I suspect that the case for this is now harder to make than it was a few years ago.
