Alcoa's plans for energy use
Friday, January 10, 2003
When the energy use of new energy efficient smelters is considered one can expect numbers close to 14,300 kWh/ton aluminium produced. According to the International Aluminium Institute http://www.world-aluminium.org/iai/stats/es002.html the average electrical power used per ton of primary aluminium produced in 2001 in Oceania (old and new smelters) was 14,791 kWh/ton. We would expect leading new smelters from environmentally progressive companies to improve considerably on this. Thus the assumption of 14,600 kWh for each ton aluminium produced used in Landsvirkjun´s profitability estimate appears much to high.
