Australia should revisit the possibility of more nuclear power after South Australia's blackout, senior Liberal Eric Abetz says.

It has been more than a week since the lights went out in South Australia and there has been fierce debate about what the blackout means for Australia's energy security going forward.

There has also been a discussion about Australia's transition to renewable energy, given South Australia generates about 40 per cent of its power from wind.

Senator Abetz said one potential power source was being overlooked.

"We should be opening the door to considering nuclear power," he said.

"South Australia itself sits on about 25 per cent of the world's known uranium reserves."

The politically-charged debate has been discussed for years, with a royal commission earlier this year raising the possibility of storing nuclear waste in SA.

Storage no longer an issue: Abetz

A major problem has always been public concerns about storing nuclear waste.

Senator Abetz said global technology had evolved, and it was safe to store the waste.

"The waste product would be at a minimum, and what's more we've got the stability of a land mass which is geologically stable, is secure, and would enable us to secure it quite safely," he said.

The call comes a day after state and federal energy ministers met in Melbourne and agreed to an independent review of the country's energy security.

Federal Labor called for a greater investment in renewable energy.

Senator Abetz said the recent problems in South Australia proved a different approach to energy supply was needed.

"With great respect to solar power and wind power, they cannot and will not provide secure base load and that has now been shown in South Australia in a manner that is devastating," he said.

Warning public acceptance will take time

Nigel McBride from Business SA recently travelled through Europe to observe nuclear energy generation in countries like Finland and France.

He said the first step in any nuclear development was winning over public opinion.

"They're talking 10 to 15 years for social licence and community consent as a process," he said.

"Now even if we did it extraordinarily quickly using their experience, it's probably a five-to-10-year process.

"Australians haven't grown up anywhere near a nuclear industry and to move them towards it will be probably glacier-like, and so maybe now is the time to at least start to socialise some of the ideas and test the waters.

"But people should be understanding they will be in for a long haul."
