EDMONTON Talk about sweet, sweet irony. An array of 1,860 solar panels was just installed at The Ice Cream Depot, a 30,000-square-foot deep freezer in Nisku, Alta., south of Edmonton. The privately funded setup generates 500kW, or half a megawatt, of electricity and will help the storage warehouse and distributer reduce its carbon footprint by 512 tonnes each year. According to president Mike Rogiani, it ll save the company tens of thousands throughout the year. We wanted to lower our carbon footprint because we re a power pig, he told CTV News Edmonton. Our energy costs continually go up. We want to be able to mitigate those costs.
