Are Electric Vehicles the Answer?

People always ask me, "Are electric vehicles the answer?" The truth is as long as you don't want to haul anything or go too far, they sure are. Remember -- I'm for anything American, and that includes electric vehicles.

But an electric battery won't power an 18-wheeler. Just like 18-wheelers, locomotives can't move on a battery. Neither can a barge or a ship. Big users require a combustion engine, and combustion engines run on one of two fuels: imported diesel or domestic natural gas. That's why I'm pushing America to switch to cleaner, cheaper, domestic natural gas.

I want our air to be cleaner, our fuel costs to be lower, and our money to stay here.

In this video, I discuss the role electric cars can play in transportation and the opportunity we have with domestic natural gas for reducing our dependence on OPEC oil.
