After the Fukushima incident in 2011, many countries decided to shrink their nuclear power programmes. This article presents recent research on the optimal role of nuclear power in reducing carbon emissions. Phasing out nuclear power would be costly, since it is currently the cheapest low-carbon alternative to fossil fuels. However, these costs would be largely offset by the implicit subsidy to R&D in renewables, which suffers from innovation externalities. Still, carbon pricing and explicit R&D subsidies would be a more efficient way of determining the future of nuclear power.

In recent years, European coal consumption has increased, while natural gas consumption has declined – despite Europe’s commitment to reduce greenhouse-gas emissions. This perverse scenario is partly attributable to EU policies. Subsidies to renewables and energy efficiency targets have the unfortunate side effect of lowering carbon prices, thus partially offsetting their environmental benefits. Raising the EU carbon price would be preferable to employing multiple policy instruments, since it would minimise distortions in energy markets, achieve cost efficiency, and raise fiscal revenues.
