Having lived in California at the moment of the so called 'energy crisis' of 2000 has made it abundantly clear to me that letting private company deal with such a strategic resource is a very dangerous game. California is still paying for that folly.
That being said, rejecting ANY participation of the private sector in EDF seems a bit like a knee jerk reaction to me. I'm not a financial analyst, but it seems to me that injecting private money could help EDF compete worldwide and be a good investment opportunity for the people. As long as it's done right and the government retains a clear majority, i don't really see a problem with that.
