Internal energy source? Hardly. However, I entirely agree on the need for a policy on replacement -- which in my view would be a stronger promotion of renewables. (I note what I observed in prior diaries here on ET: in Germany over the past few years, the growth in renewables balanced the fall in nuclear, but this was masked by the growth in net exports matching growth in gas.) *Lunatic*, n. One whose delusions are out of fashion.
You don't import electricity generated by power plants buring imported gas or coal, either... *Lunatic*, n. One whose delusions are out of fashion.
