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.

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.

Zero to 60 on less From advanced engines to better aerodynamics, today’s cars are more efficient than their predecessors. Thanks to these improvements, over the next 20 years, car fuel consumption (including SUVs and light trucks) is slated to average 50 miles per gallon (mpg), up from 30 mpg currently.
