Conservation

Energy conservation is good for the environment and our business.

At U. S. Steel, we are committed to reducing our energy usage because it is good for the environment and good for business. Data is our guide as we look for ways to improve our energy efficiency and then develop and implement projects to capture those efficiencies. Our employees apply innovative cost savings methodologies to our efforts, pinpointing non-value adding activities, defects, and waste in order to maximize our energy conservation opportunities.
