Co-Founder & CTO
JB Straubel, Co-Founder & CTO of Tesla Motors, had a segment at the 2015 EIA Energy Conference. The main topics were Tesla Motors, electric cars, energy storage and solar.
According to JB, Tesla already employs 13,000 people.
There are over 65,000 Model S delivered worldwide (maybe even 70,000 as of today), although the presentation states 60,000+.
By 2020 Tesla expects to have 1,000,000+ EVs on the roads with 70 GWh of batteries and 10 GWh of controllable charge load. Hopefully they get there as the company will need to deliver a lot of cars in less than 5 years to achieve that goal. The current plan for the whole 2015 is 55,000.
