LIGHTING-Innovation-Design

Most wind turbines are “horizontal axis,” pointing into the direction of the wind. “Vertical axis” turbines can capture wind energy from any direction, but current designs are less efficient and so get little attention and investment.

Le Parc national des Cévennes, en collaboration avec ses partenaires, a mené deux études pour évaluer l'impact de la pollution lumineuse sur les insectes nocturnes.

Des résultats concluants

La première étude, menée sur le causse Méjean, a comparé l’effet de deux types de luminaires LED : 1 800 K (température de couleur chaude) et 3 000 K (température de couleur froide) sur les insectes nocturnes. Les résultats indiquent une nette différence d’attractivité entre les deux types de luminaires : les lampes 1 800 K attirent en moyenne 30 % d’insectes en moins que les 3 000 K.

La seconde étude, réalisée en milieu urbain dans la « Capitale » des Cévennes, à Alès, a comparé l’impact de l’extinction de l’éclairage public en cœur de nuit (entre minuit et 6h) à une simple diminution de l’intensité lumineuse. Les résultats sont sans appel : l’extinction permet de réduire de 83 % le nombre d’insectes capturés.
