This is like hijacking a Tesla thread to say it's distracting us from talking about "clean diesel" gas cars.
Natural gas is not a sustainable energy source. Fracking, which is what makes it cheaper, has tons of environmental problems. Sure, it's better than worse fuels, so go ahead and upgrade. But please don't hijack threads about a sustainable planet.
That is a misleading mischaracterization. The article refers exclusively to biogas, not fracked natural gas which is the basis of your claim of "cheaper, more plentiful and cleaner than gasoline".
And it's not even sustainable if we were to purposefully scale its production (it still emits CO2), which is why the article prefers the lesser term "renewable".
