Conservation

Energy conservation is good for the environment and our business.

At U. S. Steel, we know energy reduction saves our environment and benefits our business. Our innovative research coupled with our reliable steel offers our customers and consumers energy-efficient solutions. We use empirical data to continually develop and implement energy-efficiency projects. Our employees apply innovative cost savings methodologies to our energy-efficiency project to increase efficiencies and reduce energy use. Energy reduction projects are a key component to meeting our 2030 20% GHG emissions intensity reduction goal, especially at our mining, steelmaking, and finishing operations. Energy reductions can lead to Scope 1 emission reductions (less combustion of natural gas or carbon) as well as Scope 2 emission reductions (reduction in purchased electricity).

Besides capital improvements, we can also improve energy efficiency through process innovations, such as the Blast Furnace Thermal Control Model or-hot Strip Mill Thermomechanical Control Model and our relationships with different university consortia and U. S. Department of Energy projects.




 

2020 TOTAL ENERGY USAGE





 

The graphs below show energy use from 2016 – 2020. Our use is reported in megawatt-hours, while our intensity is megawatt hours normalized by raw steel production. Note: Similar to our greenhouse gas emission reportion, for our energy consumption we included not just our steelmaking operations, but also our stand-alone mining and finishing operations.

GARY WORKS

NATURAL GAS REDUCTION

An expert control system was commissioned to reduce variations in iron production at the plant’s blast furnace operations. The result: Natural gas consumption dropped approximately 2%.


U. S. STEEL KOŠICE

ELECTRICITY REDUCTION

In 2017, U. S. Steel Košice started a program to replace high-energy/high-maintenance fluorescent lights with LED technology. Through 2019, the facility has reduced electricity consumption by 3,690 MWh per year, achieving a reduction of 1,100 tonnes of greenhouse gas emissions annually.
