Germany's government says it will shut down its nuclear power industry by 2022. It promises to reduce carbon emissions at the same time. To keep both promises through a combination of increased domestic output from renewable sources and lower demand for energy looks just about impossible.

Quite what that achieves in terms of reducing the risk of nuclear accidents and diminishing global emissions of greenhouse gases would be hard to say.
