Denmark is reconsidering its 40-year ban on nuclear power in a major policy shift for the renewables-heavy country.

The Danish government will analyse the potential benefits of a new generation of nuclear power technologies after banning traditional nuclear reactors in 1985, its energy minister said.

The Scandinavian country is one of Europe’s most renewables-rich energy markets and home to Ørsted, the world’s biggest offshore wind company. More than 80% of its electricity is generated from renewables, including wind, biofuels and solar, according to the International Energy Agency.
