By switching to Ostrom, you are **driving the energy transition in Germany**. Currently, the share of renewable energies in the German electricity market is only about 50%, meaning a mix of fossil and green electricity. The electricity from your socket is therefore referred to as "gray".

However, **Ostrom only ever feeds electricity from renewable sources into the grid**. In addition, your money automatically goes to the promotion and maintenance of renewable energies and generation plants — instead of continuing to support electricity generation from fossil fuels.
