Do you think the government's renewable energy spending is worth its cost?
Barnaby Joyce pressed Tanya Plibersek to reveal the cost of the Capacity Investment Scheme during a live Sunrise interview on Monday, 2 November 2026. Plibersek said some figures are commercially confidential.
Why it matters
The government faces growing pressure to rein in spending ahead of its December budget update. The exchange highlights the political stakes of how renewable energy programs are costed and disclosed to the public.
The Clean Energy Finance Corporation reportedly returns $7 billion a year to taxpayers, while Joyce cited $8.7 billion spent on a climate change department. The cost of the Capacity Investment Scheme remains undisclosed, with Plibersek citing commercial confidentiality.
The players
Tanya Plibersek
Tanya Plibersek is a senior Australian Labor politician who serves as the federal Minister for Climate Change and Energy.
Barnaby Joyce
Barnaby Joyce is a former Deputy Prime Minister of Australia and a senior member of the National Party.
Clean Energy Finance Corporation

The details
Joyce accused Plibersek of failing to provide cost figures she had promised five weeks earlier. Plibersek accused the Coalition, One Nation and the Greens of blocking billions of dollars in savings in the Senate, while noting that subsidies have helped about half a million Australians install home batteries and more than three million households have rooftop solar.
Timeline
Five weeks before the interview: Plibersek promised to provide renewable energy cost figures.
2 November 2026: The on-air clash between Plibersek and Joyce took place on Sunrise.
December 2026: The government's budget update is scheduled, with spending savings expected.
Big Picture
The dispute centres on the undisclosed cost of the Capacity Investment Scheme, a renewable energy program now under scrutiny as the government seeks spending restraint before its December budget update. The argument over cost transparency comes as the government points to earlier savings of $180 billion.
Households with rooftop solar or home batteries may be affected by any changes to the subsidies that have supported those installations. Taxpayers will be watching the December budget update for signs of how renewable energy spending will be restrained.
The takeaway
The dispute shows that cost disclosure is central to public trust in government energy programs. Readers should watch for the December budget update to see whether renewable energy spending is trimmed.
What happens next
The government's December 2026 budget update is expected to set out its spending decisions and savings measures.
