The city of Brisbane in Australia has the world's largest solar powered Christmas tree which features a sophisticated solar powered lighting system with 16,000 bulbs as well as foliage and decorations.
Speaking to ABC news about the Christmas tree, the city's Lord Mayor Campbell Newman said:// "We have 16,000 low-energy, solar-powered lights, there are solar panels on the top of the tree, on the star, that charge batteries throughout the day and so this tree is totally self-sufficient for its energy needs."~
