Not emitting is not that easy. We are in a transition period at the moment. Electric vehicles are here but we don’t have all the infrastructure needed to support them. Let alone the fact that battery tech is not developing as fast as we need it to.

Right now liquid fuels still have the advantage of greater energy density. If we could move to hydrogen fuels that would be cool, and we could repurpose existing petroleum facilities.

But who knows which way the tech is going to go. The only sure thing is that we are in for a wild ride one way or the other.
