Texas leads the nation in energy production. More than one-fifth of the domestically produced energy used in the United States comes from the state of Texas. The state also leads the nation in crude oil production, a fact unchanged since 1970. And the state is actively pursuing more renewable energy: In 2019 Texas generated more electricity from renewable energy sources than from coal. Texas currently has the largest number of employees working in the energy sector than any other state in the nation—607,000 employees working in the fields of fuel production, transmission, distribution, storage, and energy efficiency.
