A visionary Mayor! Bernard Laget the mayor of Châteauneuf believes in green energy and he proves it. With electricity coming from its very original wind trees and photovoltaic panels, it is in the production of green hydrogen that the former professor of the ÉNISE, the National Engineering School of Saint-Étienne has embarked on. Completely self-sufficient in energy, the Château du Mollard demonstrates the relevance of his ideas, which many municipalities are observing with interest.
