The executive order would require retrofitting all federal and postal vehicles to run on natural gas. And use post offices as filling station locations for those vehicles and retrofitted private vehicles. Our abundance of clean natural gas is larger than all of the oil in OPEC. This step could save billions of barrels of oil, provide jobs, and reduce fuel costs, eliminate the need to rely on OPEC.
Every year we encounter human and habitat disasters from oil and derivatives. Old refineries explode and oil spills and leaks destroy eco-systems. It would reduce CO2, CO, and NOx in the atmosphere by billions of tons per year.
