Bornholm, the picturesque Danish island in the Baltic Sea, is about to take on a key role in Europe's energy supply. With an ambitious project, the 588-square-kilometre high seas island wants to exploit the full potential of renewable energies and thus not only supply the whole of Denmark with electricity, but also transmit a considerable proportion of the electricity generated to Germany.

Green electricity in abundance
The centrepiece of this visionary large-scale project is the planned offshore wind farms that will soon line the coast of Bornholm. With an expected capacity of 3 to 3.8 gigawatts, these wind farms will generate enough green electricity to supply around three million households. This is about three times the capacity of conventional wind farms.

The rise of wind power
The impressive numbers continue: The Danes want to install a total of 150 wind turbines, each reaching an enormous height of 268 metres above sea level. These gigantic turbines are not only impressive in their size, but also in their efficiency: a single rotation of a wind turbine can supply enough energy to charge 1,600 smartphones.

Sporty schedule: Bornholm's energy transition by 2030
The timetable for the energy island is ambitious: The offshore wind farms are to be fully constructed by 2030. The aim is to initially bundle the electricity generated on Bornholm and then transmit it to the Danish mainland and Mecklenburg-Western Pomerania via submarine cables.

Pioneer: Belgium looks enviously to Bornholm
But Bornholm is thinking even further ahead. The surplus electricity produced by the wind farms is to be used to produce green hydrogen - a key component for the decarbonisation of various sectors such as transport and industry. The project on Bornholm has attracted the attention of experts around the world. Belgium has already expressed interest in following the Energy Island's example. It is clear that Bornholm not only marks a turning point in the energy transition, but also paves the way for other regions to make the transition to a more sustainable energy future.
