"We are seeing the biggest changes in our energy and transport systems since
industrialisation. By 2026, global renewable energy generation is expected to
match total fossil fuel and nuclear output. Building the wind and solar farms,
batteries and electricity networks we need to run our system on renewables will
use a huge array of mined minerals, known as “transition minerals”.
The numbers are staggering. The International Energy Agency estimates a sixfold
increase in demand for these minerals by 2040 to meet climate targets of well
below 2℃ of warming. We could need 21.5 million tonnes for electric vehicles
and battery storage alone.
Transitional minerals include metals such as lithium, cobalt, copper, graphite,
magnesium and nickel. They also include rare earths like neodymium,
praseodymium, dysprosium and terbium.
Currently, mining provides almost our entire supply. The scale of demand for
these minerals could result in almost 400 new mines by 2035.
To put this in perspective, Australia has around 350 operating mines. More than
50% of the world’s lithium and much of its copper, cobalt, nickel and rare
earths come from our mines.
Australia is hosting the World Mining Congress this week. A key issue for the
industry is how we can ensure the minerals needed for the energy transition are
sourced responsibly."
