France to turn off office and shop lights at night

PARIS (REUTERS) - French shops and office buildings will have to turn off their lights at night to save energy and reduce light pollution, the French environment ministry said today.

From July 1, all non-residential buildings will have to switch off interior lights one hour after the last worker leaves the premises. All exterior and shop window lighting will have to be turned off by 1am.

Local authorities will be able to allow exceptions for Christmas lighting and other local events.

The new law will save about two terawatt per hour of electricity a year - the equivalent of the annual consumption of 750,000 households, the ministry said.
