Calgary's lights are too bright in space, says city council

Some city council members think Calgarians need to do a better job of turning down their lights literally, and a city council committee agreed by voting to amend planning policies for light pollution in future developments.

Canadian astronaut Chris Hadfield tweeted a picture of Calgary from spaceTuesday,and many of themajor roads were clearly visible.

The view from spaceused to be even brighter before the city switched to energy efficient bulbs for streetlights and pointed them downwards.

Aldermen heardWednesday that light pollution is also affecting the ability of theUniversityof Calgary's observatory south of the city toview the stars.

Ald. Brian Pincott says turninglights downwardsaves money, and is environnmentally responsible, but the city can't force current light polluters to do so.

"Grandfathering is always an issue," he said. "We can't go back and make everybody take their offending lights down, as much as we'd want to. But the moment they have to redo their lighting, they would have to fall within the guidelines."

Calgarians can have their say on the new policy when it goes to city council in April.
