Tesla moves beyond electric cars with new batteries

San Francisco

TESLA Motors Inc CEO Elon Musk has unveiled a suite of batteries to store electricity for homes, businesses and utilities, saying that a greener power grid furthers the company's mission to provide pollution-free energy.

"Our goal here is to fundamentally change the way the world uses energy," he said at an event on Thursday at the company's design studio in Hawthorne, California. "We're talking at the terawatt scale. The goal is complete transformation of the entire energy infrastructure of the world."
