In Our Element: 90 Years
of Energy Workforce
In 1938, the Association adopted the name Petroleum Equipment and Suppliers Association (PESA) , which grew exponentially in size and influence over decades of operation. The organization solidified its place as the preeminent energy technology and services association with the 2021 merger of PESA and the Association of Energy Service Companies (AESC) — becoming the Energy Workforce & Technology Council.
Through 90 years of challenges and successes the industry remains “In Our Element,” building on the foundations of the past while trailblazing the future of energy.
We were “In Our Element” codifying the first safety standards, and we are in our element today developing and deploying the latest completions technology.
We were “In Our Element” providing fuel to support our allies during WWII, and we continue providing fuel to our allies in Europe today.
We are “In Our Element” answering every call to provide the cleanest and most efficiently produced energy in the world.
All the while, the world lives “In Our Element,” utilizing hydrocarbons to spur advancements in every industry to sustain our modern way of life.
While the industry has transformed over the last 90 years, the spirit of hard work and innovation that defines the individuals of the Energy Workforce has never faded.
That enduring spirit has earned the U.S. energy industry the reputation of reliability, ingenuity and success that powers the world.
