The North American continent is the only continent in the world without electrified rail.  Rail is the most energy efficient means of transporting goods yet we use trucks to do the bulk of our transport in this country.

     Tesla is about to turn this into not a bad thing with their new electric truck (semi tractor trailer).  Capable of doing 65 up a 5% grade with an 80,000 lb load and a 500 mile range with the same load, and a half-hour charge time so your truck can charge while you take a meal break.
