France to turn off office and shop lights at night

PARIS Wed Jan 30, 2013 6:15am EST

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 on Wednesday.

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 1 am.

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

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

Environment Minister Delphine Batho said it would also make France a pioneer in Europe in preventing light pollution, which disrupts ecosystems and people's sleep patterns.

The unit is “terrawatt-hours”, product, not quotient. It’s not terrawatts per hour.

They are turning the lights out in France because the economy is collapsing. Not because they want to help out star-gazers.
