Energy Use

The manufacture and processing of steel is an energy-intensive process.

For example, significant quantities of coal for the blast furnace, natural gas and electricity to reheat and roll steel slabs into thin sheets, and electricity for coating and painting a range of downstream steel products, are used.

BlueScope Steel's global energy consumption has remained relatively constant over recent years. In the fiscal year 2004/05, 139.7 petajoules of energy was used to manufacture 5.72 million tonnes of steel.

The Company uses an energy intensity index to calculate how efficiently we use energy compared to a base year. A number lower than 1 shows an improvement in energy efficiency. This year the energy intensity index remained relatively constant at 0.93.
