Energy efficiency
ExxonMobil constantly strives to improve performance and streamline our processes in order to improve energy efficiency and reduce environmental impact.
Executing at scale
Deploying proven technology to reduce emissions
Technologies allow us to reduce, reuse and recycle energy throughout our operations. Running large upstream, refining and chemical operations to provide the products consumers rely upon generates tremendous amounts of excess heat. To ExxonMobil engineers, that lost heat offers opportunity.
With cogeneration we capture the waste heat and utilize it for our manufacturing processes, resulting in a reduced need for boilers, not to mention the fuel saving that goes with those boilers. Due to its inherent energy efficiency, the use of cogeneration leads to reduced greenhouse gas emissions. Our cogeneration facilities enable the avoidance of approximately 6 million metric tons per year of greenhouse gas emissions.
~ 5,400 megawatts
of gross cogeneration capacity in more than 100 installations, which is equivalent to the annual electricity needs of 4.3 million U.S. homes
A leader in cogeneration
Over the past decade, we have added about 1,000 megawatts of cogeneration capacity and continue to develop additional investment opportunities.

Producing power efficiently for our own operations
There’s nothing flashy about cogeneration, and in a hashtag environment, the term is rarely trending. But what cogeneration lacks in headline-grabbing cache, this emission-reducing technology makes up for by producing concrete results.

What an energy efficient grid could look like
Two years ago, ExxonMobil and the U.S. Department of Energy’s national laboratories – including the National Renewable Energy Lab (NREL) and National Energy Technology Lab (NETL) – expanded their work together to research advanced technologies with the potential to help societies achieve a lower-carbon future. Within the partnership’s purview is a project on how to optimize the energy grid to meet future energy demands while lowering emissions with the most cost-effective approach.
