The $2 billion recapitalisation of the Clean Energy Finance Corporation has revived debate about the future of Australia’s government-owned green bank, with renewable advocates calling for lower investment return hurdles while the Coalition has attacked taxpayer financing of green energy projects.

The CEFC has supported more than $70 billion worth of renewable and low-carbon projects since it was created by the Gillard government 13 years ago. Last week the Albanese government injected a further $2 billion into the fund to accelerate further investment.
