Nuclear is (about) 80% of French electricity production;
and about 18% of total energy use.
Royal should have said 17% of energy, not of electricity, but she was a lot righter than Sarkozy who appears to have picked his number on a sort of 50-50 basis, like, I've got half a chance of being right and half of being wrong.
I've been particularly fond of Royal's bold efforts against nuclear power. This is something the French actually did right, has major international implications (her position vis-a-vis Iran) and yet she is willing to oppose, from an ecological standpoint, in order to encourage renewables.
Whatever happened to nuclear waste, anyway?
