The push to net zero by 2050 is expected to require a boom in solar energy - but all those solar panels need aluminium, and Australian experts say the projected aluminium demand is itself a global warming risk. They say that by 2050, some solar roadmaps predict we will need around 85 times the current solar energy production. The team say this means the annual demand for solar power by 2050 will require more than 40 per cent of the current global aluminium production. Additionally, the researchers point out a key concern for this large aluminium demand is its large global warming potential.
