 Due to France's very low-carbon power electricity grid, the carbon dioxide emissions from charging an electric car from the French electricity grid are 12 g per km traveled.This compares favourably to the direct emissions of one of the most successful hybrid electric vehicles, the Toyota Prius, which produces carbon dioxide emissions at the higher rate of 105 g per km traveled.The nuclear fusion project ITER is constructing the world's largest and most advanced experimental tokamak nuclear fusion reactor in the south of France.
