There is approximately 308.794 trillion cubic feet of untapped natural gas and roughly 57 billion barrels of oil yet to be refined in North America alone. Internal combustion engines aren't going anywhere in the foreseeable future. They've been trying to make electric cars a feasible alternative since the crude invention of them between 1832 and 1839 (the exact year is uncertain). I'm all for alternative fuel sources to decrease American foreign oil dependence, but they're looking in the wrong place.
