DARLINGTON Borough Council's efforts to use "greener" sources of electricity have been recognised.

The council made a commitment last year to procure all its electricity from natural sustainable sources, fed into the National Grid from wind farms and hydroelectricity sites.

The authority struck a deal with npower, aimed at reducing carbon emissions in its buildings and from street lights, traffic lights and road signs.

Yesterday, npower representatives awarded certificates to the council for taking up the initiative.
