Polarstern is Munich's independent green energy provider, where households and companies receive exclusively certified tariffs and products with 100% green energy.
Founded as a social business, Polarstern is now a member of the Economy for the Common Good and certified by a B Corp. Because a fair energy transition also requires a different approach to business. For every kilowatt hour of green electricity, green gas, or a special tariff for electric cars or heat pumps sold, we invest heavily in the expansion of renewable energies in Germany. Certified by the Green Electricity label, among others, and awarded multiple times by ÖkoTest, Robin Wood, and Utopia, among others, every switch enables clean energy for families and entire villages in developing countries. After all, the energy transition and climate protection know no national borders.
This is how Polarstern is changing the world with energy. Join us.
