Elon Musk: "majority" of vehicles will be electric by 2030 [w/video]

The oft-outspoken chief executive officer of Tesla Motors, Elon Musk, is chomping at the electric bit again.

While speaking at the TechCrunch Disrupt conference in San Francisco recently, Musk, a 40-year-old billionaire recently profiled by Bloomberg Risk Takers, shared an enthusiastic vision of electric cars and solar energy with the room-filling crowd.

Musk said that, "Starting a company is like eating glass and staring into the abyss of death." Even so, that's the attitude it'll take to solve the big problem of the 21st century, one of which will be sustainable energy. Musk even detailed his vision of the world 20 years from now, claiming:

On the energy side, I think by the mid-point of the century solar power will be the single largest source of energy. Maybe not a majority, but the largest single source.

Perhaps it shouldn't be a surprise, but Musk was also incredibly optimistic about EVs, stating that electric vehicles will make up the majority of new vehicles within two decades. Yes, that's over 50 percent by 2031. This is way beyond other estimates, and shows that Tesla's CEO, a man who's quite possibly one of the leading innovators of our day, is a true believer in electric vehicles.
