The LEGO Group’s parent company just announced that it is investing over half a billion dollars (3 billion Danish krone or 400 million euros) on an offshore wind farm off the coast of Germany.

The wind farm will have nearly 80 turbines, and will provide more power than LEGO’s production facilities will be projected to require in 2020, thereby enabling the company to become effectively energy self-sufficient within the next eight years.

This news follows LEGO’s announcement last summer that they are reducing LEGO packaging box sizes and obtaining their wood products from sustainable sources.
