Of all the ways to meet the world’s expanding energy needs, efficiency and conservation are the cheapest and most beneficial to the environment. Using energy more efficiently helps preserve our finite natural resources, lower energy costs and reduce carbon emissions.
using energy more efficiently
Chevron continues to find new ways to use energy more efficiently in its own operations. From 1992 through 2012, we used our Chevron Energy Index (CEI) to track energy use performance across all operations and measured a 34 percent improvement. The CEI measured our operational energy intensity based on estimated technological improvements and operational performance. As our assets have grown in size, complexity, and diversity, we recognized that energy efficiency could be measured better and ultimately improved.
We achieve energy savings in big and small ways. Chevron employees and contractors make energy efficiency a constant priority through everyday acts such as maintaining our equipment so that it runs smoothly, and through complex projects, such as building high-efficiency power plants. Chevron’s Pipeline & Power organization collaborates with the company’s Upstream and Downstream businesses to help lower their energy costs, test new technologies, achieve efficiency gains, manage emissions and improve power reliability.
We have five metrics to track energy performance:
- Upstream Energy Intensity
- Manufacturing Energy Index (Refining)
- Non-Manufacturing Energy Index (Oronite, Lubricants, etc.)
- Pipeline Energy Intensity
- Shipping Energy Intensity
The metrics are not only easier to understand than the CEI, but their segment-specific nature of these new metrics also helps drive energy performance improvements.
Cogeneration is a fuel-efficient process that produces steam and electric power simultaneously, generating electricity and thermal energy more efficiently than traditional power plants. Chevron operates cogeneration units at some refineries, Upstream production facilities and other sites worldwide. In 2017, our cogeneration units had a combined generating capacity of 1,075 megawatts, enough to power approximately 870,000 U.S. homes for a year.
Chevron’s Upstream operations manage energy efficiency by identifying, evaluating and implementing projects that will conserve energy. An example of success in reducing energy consumption within Upstream operations is our San Joaquin Valley business unit. Since 2014, this business unit’s energy management projects have resulted in a mitigation of approximately 180,000 metric tons of GHGs, or the equivalent of the GHGs from the electricity used by approximately 22,000 U.S. homes for a year. Another example of success is in the Gulf of Mexico, where power generation is optimized through the use of predictive analytics tools. Similarly, in our IndoAsia business unit, we reduced energy intensity by more than 27 percent between 2014 and 2016. This improvement was achieved in part through the establishment of the Integrated Optimization Decision Support Center, which monitors the day-to-day energy performance of surface facilities and provides recommendations for optimizing energy efficiency.
energy efficiency – green buildings
We strive to reduce the environmental footprint of our facilities by following frameworks such as the Leadership in Energy and Environmental Design (LEED) certification process, an internationally recognized system that certifies a building’s environmental sustainability. Chevron has a number of LEED-certified buildings. In 2008, Chevron’s office building in Covington, Louisiana, was the first in the state to earn Gold certification in the LEED program. In 2018, Chevron achieved LEED Gold certification in New Construction for its campus in Midland, Texas.
energy efficiency partnership
Chevron is a leadership sponsor of the Energy Efficiency Center (EEC) at the University of California at Davis. This partnership provides us with insights from the EEC’s research efforts and from participants in different sectors of the energy efficiency industry. In 2009, Chevron provided a $2.5 million endowment for a permanent chair to head the EEC.
