> Gigafactory 1 battery production reached an annualized run rate of roughly 20 GWh

Kind of interesting...the typical laptop has a 50 Wh battery, and there are about 160 million laptop sales per year. A typical smartphone has a 5 Wh battery and there are about 1.5 billion smartphones sales per year. So that one factory makes just about enough batteries for all the laptops and smartphones.
