Galveston County is located in the energy capital of the world.

According to the Greater Houston Partnership, “Houston is the energy capital of the world and the “brain trust” for virtually every segment of the oil and gas industry, including exploration, production, transmission, marketing and supply with a growing focus on renewable forms of energy technology.”

Houston employs nearly a third of the nation’s jobs in oil and gas extraction. Houston is home to 4,800 energy-related firms and is at the forefront of foreign investment in energy.

Additionally, Houston’s petrochemical sector is experiencing record levels of growth with $50 billion dollars of facility construction underway.

Petrochemical Powerhouse

The Texas Gulf Coast has 25% of the nation’s refining capacity, capable of refining 4.8 million barrels of oil per day.

Houston has 40% of the nation’s base petrochemical and manufacturing capacity.
