There's a word on the back of the original Lego box:
The ambition of the Lego Group is to make the world a better place for future generations. To achieve this ambition, our goal is to make the production of renewable energy redundant by 2020. As a first step, our parent company, KirkBI A/S, invested nearly 400 million euros in the construction of a German offshore wind farm. LEGO 4002015 1 Borkum Riffgrund 1, the German Borkum Rockboard Marine Wind Power Plant, was launched in 2015 as a set of 359 parts of the Creative Centrator Expert series of maquis。
