With aluminum, it's all about give and take. Aluminum production consumes a great deal of electricity, but the material itself gives back as a major component of power transmission systems. The metal has been the material of choice for electrical transmission applications for more than 100 years for investor-owned utilities, rural electric authorities and electrical cooperatives, said Ian Hewett, president of the Alcan Cable unit of Alcan Inc., Montreal. Aluminum cable accounts for the vast majority of the 212,000 miles of existing transmission lines that exceed 230 kilovolts in North America, Hewett said.
