The French Ministry of ecology, sustainable development and energy announced that from July 1st a new law will come into effect that will require all non residential buildings to turn off all unnecessary lighting during nightime. Office buildings, shops, malls and other commercial buildings will be required to turn off interior and window lighting as well as lit signs every night from 1 am until 7 am.
Office buildings will also be required to turn off all interior lighting one hour maximum after closing time.
According to French Ministry of ecology, this new law will save enough energy to power 750,000 households, save 250,000 tons of CO2 emissions and €200 million in electricity bills.
Certain touristic areas such as the Champs-Élysées in Paris and 40 other townships will however be allowed to keep the lights on.
