Our work needs lot of energy (machines, dryers and kilns). The energy we use is produced by our water mill, then, when we are not obliged to stop our water mill because of dry season or fish regulations... we use this "green" electricity.
It means this electricity made with water doesn't produce CO², and is not using earth ressources.
This is a 100% safe energy that doesn't arm environment.
