Nationwide green-energy provider with fully English website, app and live chat. Pay a flat €6 basic fee, get renewable power at cost, monthly cancellation and no hidden mark-ups.

Utilities

Ostrom supplies 100 % renewable electricity across Germany and lets you manage everything in English—from sign-up to meter readings—via its app or web portal. A flat €6 basic fee means the company earns the same from a studio as from a villa, so it actively nudges you to save power instead of selling more.‍
