How it works

Our servers run day and night; the sun doesn’t. Here is how we offset every kWh.

By day

The sun is shining: our panels produce electricity. Our servers use a small part of it; the rest — by far the largest share — is fed into the grid and powers our neighbours directly.

The grid as a battery

A server runs day and night; the sun doesn’t. Rather than storing our electricity in batteries — expensive to manufacture, replace and recycle — we feed it into the power grid. During the day, our surplus directly supplies nearby consumers. At night, our servers draw their power from the grid.

Over the year, the balance is clear: our plants produce far more than our infrastructure consumes. Every kWh used by our services is therefore offset by a solar kWh that we produced ourselves, in Switzerland.

What this means for you

Why not run directly on our panels?

Our servers are in a secure data centre, our panels on well-exposed rooftops. The grid connects the two. This lets us build plants where the sun shines best and the roofs are largest, while guaranteeing our servers an uninterrupted power supply.
