A council in Wales has approved a plan to reduce its carbon footprint. Wrexham will put in place energy-efficient bulbs instead of all its residential street lights. The Welsh Assembly Government has pledged £280,000 towards the scheme, which will cost £336,000. Wrexham council will contribute £36,000, with the remaining £20,000 being paid by Offa Community Council. Work must be completed by March 2011 to qualify for the assembly government grant. There are no plans to switch off any lights.
