Tesla is an energy company that just happens to make cars, batteries, and solar panels. Or so they would like to be.

If you look a the energy industry now, there's an iron triangle, if you will, between fossil fuel extraction, electric utilities, and the automobile industry. Tesla is aiming to replace all three sides with solar, batteries, and electric cars. A person could use Tesla products and, in theory, not interact with the current energy sector of the market at all. Which, if it works, would be some kind of disruption!
