If the world's renewable energy resources were a power station, the plant would be millions of gigawatts in size. To put that into perspective, Australia produces all of its electricity from just 70 gigawatts.
There's enough pollution-free, renewable energy out there to power humanity for the entire Anthropocene. That's the age of humans, just as the Mesozoic was the age of dinosaurs.
But the markers of our era won't be Tyrannosaurus teeth or asteroid craters. They'll be giant landfills of single-swig, plastic water bottles, effectively fossils the moment they're made.
We have no idea how long the Anthropocene will last. But if we don't stop warming our planet, it will be geological history's shortest era.
Hydrogen offers us a colossal opportunityThe solution is hydrogen.
Hydrogen is the most common element in existence. In fact, the universe is 75 per cent hydrogen by mass — so we'll never run out of it.
It's also the simplest. To make it, all you need to do is run electricity through water.
That's green hydrogen, the purest source of energy in the world — and one that could replace up to three quarters of our emissions, if we improve the technology and had the scale.
