How do you reduce energy consumption and avoid polluting the environment, while maintaining a high standard of living and staying economically viable? France has decided, for now, that the answer is nuclear energy. It is the most nuclear country in the world: almost 90 percent of the country’s electricity is produced in 19 nuclear plants. But as Europe and the rest of the world moves away from nuclear, how will France keep up?

I went to Lorraine, in the east of France, bordering Belgium, Luxemburg and Germany. It used to be a center of the coal mining industry. It's also home to a nuclear plant as well as sources of renewable energy. It’s an ideal region to look at the past, present and future of energy in France.
