While at the World Energy Innovation Forum on Tuesday, Tesla CEO Elon Musk continued to map out his vision for the future of the planet by stating that the world will need many Gigafactories in the future.  Hundreds of them - just like the one the EV maker is planning to complete itself in 2017.

The demand for these gigafactories will come primarily from two sources; initially from the automakers who will look to these super plants to churn out lower cost batteries at a higher rate, and secondly from the world's increasing power storage needs as the grid's energy profile changes.

Tesla's first "gigafactory" will be located in one of four five US states; Arizona, Texas, New Mexico, Nevada as well as newly re-introduced California (as per the company's last financial update).   Tesla expects the savings on volume production of cells to be in the neighborhood of 30%

“I think we can probably do better than 30 percent,” Musk said yesterday at the company’s Fremont, California, plant according to Bloomberg.  As carmakers increase demand for batteries “there’s going to need to be lots of gigafactories. Just to supply auto demand you need 200 gigafactories.

Tesla themselves plan to not only build batteries for their cars, but as part of renewable green energy storage solutions (such as solar and wind power) with partners like Elon Musk-related company SolarCity.
