"Chinese automaker BYD Co Ltd expects the country’s shift to cleaner new-energy vehicles (NEV) to be complete in just over a decade, an aggressive timeframe that would challenge traditional carmakers in the world’s top auto market.

All vehicles in the country will be “electrified” by 2030, which could range from full electric cars to mild hybrids, BYD Chairman Wang Chuanfu said on Thursday."

BYD has a vested interest in China being 100% electric by 2030. No concrete date has been given yet but it's been assumed that 2040 would be the target date for 100% electric cars in China; the actual date is not yet known. If China made 2030 the date it would be huge for Syrah.

24.38 million car sales in China for 2016 * 40kg of spherical graphite = 975,200 tons of spherical graphite needed per annum if all cars were electric.

(Rather than bickering insert your own figure above to reach your own estimate).

This ignores demand from Europe, the USA, Japan, India and the rest of the world.
