GLASTONBURY, England, June 24 (Reuters) - A giant spider breathes fire into the cloudy night sky over Glastonbury's Arcadia stage as thumping beats from electronic music duo the Chemical Brothers excite hundreds of fans. The colossal metal arachnid, made from recycled military hardware, has been a fixture at England's world-famous music festival for years, but this time Arcadia and all the other stages at Glastonbury are being powered entirely by renewable energy sources, organisers say. This year, all its generators, including those that power its main Pyramid stage will run on hydrotreated vegetable oil, a renewable substitute for diesel made from waste cooking oil, organisers said. But for their part, organisers are trying to mitigate the overall impact as much as possible. This year, a temporary, 20-metre wind turbine - another source of renewable power - towers over a section of Worthy Farm, powering food stalls with enough energy to run 300 fridges a day.
