How much energy is required for the production of aluminum?

The energy required for the production of aluminum is substantial. Producing one ton of aluminum typically requires around 15-25 kilowatt-hours of electricity, largely due to the process of electrolysis, which is used to extract aluminum from its ore, bauxite. This high energy consumption is a significant factor in aluminum production costs and environmental impact. The energy required can vary based on the efficiency of the smelting process and the source of electricity used.
