In 1994, Jeff Bezos famously spotted a stat that made him leave his high-paying PE job to start Amazon: 💡 The Internet was growing 2300% per year. What are the generation-defining stats of today? I'll post a few to kick things off...

That's why in charts like the one I tweeted last night you'll see that our need for graphite for our future gigafactories is actually GREATER than our need for lithium. Look at the height of the bars! But cathodes are sexier than anodes so no one pays much attention
Replying to @EdConwaySky
There’s a simultaneous race for battery materials. Doubtless you’re already aware of this but the scale is nonetheless mind-boggling. This chart shows you how much the UK will have to increase its supplies of lithium/cobalt/graphite by 2030. Lithium/graphite up by 9,000%!

The Humber Refinery in NE England.
This place looks and smells like a ghost of fossil fuel history. It's where they turn crude oil into petrol, jet fuel & many other petrochemical products.
It won't seem the obvious place to start a thread abt batteries.
But bear with me

Yesterday I rented a boat and took the leader of one of Flexport's partners in Long Beach on a 3 hour of the port complex. Here's a thread about what I learned.

In 1965, nuclear power generated slightly more electrons than renewable power. That gap widened for 40 years, tightened for 15, and now Renewable Power > Nuclear. bp.com/en/global/corporate/e…

(3/4) ‘In the 60 years before the Civil War, the daily amount of cotton picked per enslaved worker increased 2.3% a year. That means that in 1862, the average enslaved fieldworker picked not 25% or 50% as much but 400% as much cotton than his or her counterpart did in 1801.’

(4/4) ‘Overseers closely monitored slaves’ picking abilities and assigned each worker a unique quota. Falling short of that quota could get you beaten, but overshooting your target could bring misery the next day, because the master might respond by raising your picking rate.’
