Hofer creates the world's smallest eco-power plant

A potato and a handful of wired metal plates: That's what potential large customers of Energie Wasser Bern are receiving these days. With the potato mail, compiled by Hofer, they are encouraged by the Bernese energy supplier to build their own mini eco-power plant and invited to the Forsthaus energy center by handwritten/personal card. In this way, the mailing playfully spans the arc from the mini power plant to Bern's flagship of sustainable energy production and at the same time draws attention to the customized energy solutions for large-scale consumers.

Potential business customers who will not be able to choose their electricity supplier until a later date will also be contacted. Here, Energie Wasser Bern is using a brochure to raise awareness at an early stage.
