Tesla to build two or three more US Gigafactories
Tesla CEO Elon Musk has said that he will open "two or three" Gigafactories in the US over the next few years, but refused to be drawn on details. Musk anticipates most new cars in the US to be electric vehicles (EVs) within a decade, and EVs to virtually dominate the market in 20 years, prompting the need for a network of global Gigafactories to keep up with demand for batteries.
Tesla will open '2 or 3' more Gigafactories in the US It has to keep up with electric car demand on its home turf.

It's no secret that Tesla wants to open Gigafactories around the world to keep up with demand for electric cars and storage batteries, but how many of those will open in the US? Now we know: Elon Musk has confirmed that "2 or 3" additional factories will open in the US over the "next few years." He's not offering a firm timetable, to no one's surprise (the first factory isn't even finished yet), but the news makes it clearer than ever that Tesla expects plenty of demand.

Musk was definitely strategic with the announcement. He was speaking in front of the National Governors Association, which is full of politicians looking for economic opportunities -- he's no doubt hoping that governors will jockey for a Gigafactory (and offer incentives) in their state. At the same time, though, it may be a realistic forecast. Musk expects most new cars in the US to be EVs within 10 years, and to virtually dominate the market in 20. If Tesla doesn't have enough factories in place, it risks losing business as electric transportation hits the mainstream.

The talk also saw Musk weigh in on a few other topics. He's not opposed to self-driving car regulations, but he believes they should expire as technology evolves. Also, he believes that car security is a high priority. He notes that Tesla cars already have "special encryption" that protects vital systems like the powertrain and brakes, and he's entertaining the idea of a kill switch (of sorts) that no hacker could touch. Don't count on governors heeding his regulatory advice, but it won't be surprising if future Teslas are better-equipped to deal with online threats.
