"huge amount of minerals". ....... no different to coal oil or gas except it doesn't increase GHG emissions.
as I've been saying for years not all energy storage is lithium batteries. take a look at flow batteries as another example.
for 9 years investments like this were discouraged because the Libs didn't have a plan, refused to set targets for emissions reductions and were still trying to abolish the renewable energy efforts established by the Gillard mob. now at last we are getting investment.
did you have a look at the CSIRO GenCost assessments for future energy production costs? I invited you.
