The energy industry doesn't really care much for romance. Numbers and copper are her profession. But if she wants to make her customers dream, all she needs is the word self-sufficiency. To be king of my own island – who wouldn't indulge in that?

The technology for this is available, from the solar system to the diesel generator. And at the latest since the country has been debating gas storage, blackouts and energy-saving appeals, the idea that it is its best supplier has been en vogue. Even the most expensive battery storage system sells itself, because many are united by the feeling: We can no longer trust the organizers of this system, everything is getting more and more complicated, we are at the mercy of the energy policy volts of politics. They think they are in greater safety without a mains connection, but equipped with energy technology right up to the ridge.

But there is a problem. Because real island life, without connections to the neighbor, does not make everyday life safer. It is certainly not resource-saving and economically sensible, at least if everything is to run as reliably as in the German or European interconnected grid. This is complex, it can get stuck, it needs intelligence and double bottoms, no question. But the more connected and larger a system, the better it can compensate if it is disturbed at one point, and the faster it recovers, for example from a power failure.

Energy supply is a joint task. If you want to contribute something, for example with solar power from your own roof, this should be made as easy as possible. But to suggest that consumers' energy worries will dissipate if they only isolate themselves to the maximum is unfounded. Such an island life can become lonely.
