Haagse Stroom is a non-profit citizens initiative. We work together with various organizations including 070Energiek, Groene Regentes, Duurzaam Den Haag, the municipality of The Hague and the Province of South Holland.

With 070Energiek we are looking for solar roofs, but we are also working on saving energy through the organization of EnergyParties.

Haagse Stroom is a member of om | nieuwe energie

Like many other local energy cooperatives, Haagse Stroom is a member of the national energy collective om | nieuwe energie, the largest and the greenest in the Netherlands.

Scoring a 10 om| nieuwe energie was voted the greenest energy supplier in the Netherlands for the fifth time in a row, in the annual independent research conducted by the Consumers’ Association, Greenpeace, Nature & Environment and WISE. With that score om | nieuwe energie outdoes not only the large energy companies but also a number of well-known green suppliers.
