Energy — Approach
Alcoa has emphasized energy efficiency since the early days of the company. In 1900, the electrical energy requirements to make a kilogram of aluminum from alumina were more than 55 kilowatt hours (kWh). By 2000, our electrical energy requirement was reduced to 15 kWh per kilogram. Today, our best performing plants can produce the same quantity of primary metal using only 13.3 kWh per kilogram. Each smelter has created an Energy Committee whose mandate is to increase energy efficiency through various measures, from simple changes in work processes all the way to technology innovations.
