The project PEACE_Alps, through the regional Park Chasseral, gave impetus to the organization of the first night festival in Fontaines, one of the villages of the municipality of Val-de-Ruz. This evening was the kick-off of a 6-month test phase of the shutdown of public lighting, from midnight to five o'clock. If the experience is conclusive, the measure will be extended to all villages in the municipality with impact on energy savings and starry nights, for residents and nocturnal animals.

On October 20, in a festive atmosphere, the inhabitants rediscovered the beauty of a dark night sky, 110 years after the arrival of electricity in the village. Schoolchildren have been actively involved in offering songs and supplies for the 400 people who wandered from one animation to the next: fire jugglers, owls’ songs or magical tales, and to guide the crowd in the dark, a lady on stilts, adorned with lights...

If, on the whole, the measure is a priori well received, the night-time extinction of public lighting is seen by some as a step backwards. Others fear traffic accidents involving pedestrians or feelings of insecurity. However, according to statistics, cutting off public lighting would not increase either crime or accidents. An alternative solution is to modulate the light intensity during the night.
