Australia produced enough renewable energy to power 70 per cent of households last financial year, new data shows, but advocates warn the booming industry will flounder unless the Turnbull government commits to a clean energy target.

The government is sharply divided over whether to adopt the target, the central recommendation of Chief Scientist Alan Finkel's review of the national electricity market.

Sunverge chief executive Ken Munson said Australia's high penetration of rooftop solar, where one in five homes use power from the sun, put the country at the forefront of the transforming energy industry.

New data to be released on Monday shows Australia produced enough renewable energy to power 7.1 million homes, or 70 per cent of households, in the year to June.

This avoided carbon pollution equal to removing 8.1 million cars from the road for a year – more than half the cars in Australia.
