ENERGY STAR Focus on Energy Efficiency in Petroleum Refining

The “petroleum refining focus” is a partnership between EPA’s ENERGY STAR program and petroleum refiners to improve energy efficiency within their operations. Tools are available here to help improve manufacturing energy efficiency, save money, and reduce greenhouse gas emissions.

Annual Petroleum and Petrochemical Refining Focus Meeting; September 2019

Petroleum refiners can get started on a path of saving energy by using the ENERGY STAR Guidelines for Energy Management to build an energy management program, and then work within this petroleum refining focus to learn best practices from the industry. If you are a petroleum refiner who wants to get involved in your industry’s efforts to save energy, contact
