The recent deluge of low-cost shale gas is already changing the way the country runs. Electric utilities are turning to gas to power their turbines, and chemical companies that rely on the fuel are coming back to the U.S. after years of investing overseas.
But the holy grail is transportation.
Every day, we consume 70% of our oil getting from place to place—and produce more than 30% of our greenhouse gases along the way. If we could run our vehicles on natural gas, it could kill two birds with one stone: Not only is natural gas a lot cheaper than oil right now, but its emissions are much cleaner than gasoline or diesel.
