Riding on the crest of its success with the recently passed carbon pricing scheme, the Australian Green Party stepped up Wednesday its campaign of seeing through the country to be wholly functional using renewable sources of energy.

Aiming to reduce overall carbon emission by 80 percent over the next four decades, Greens Senator Christine Milne called on her colleagues to leap a bit further and gradually adopt measures that would transform Australia as a bastion for alternative fuel sources such as sprawling wind farms and solar panels.

"We need to get to 100 per cent renewable energy as quickly as possibly in this country," the Greens deputy chief was reported by The Australian as saying.

Her declaration, however, was viewed as a radical turnaround by other members of the Australian Parliament, with Prime Minister Julia Gillard immediately distancing herself from the Greens' stand following months of collaborating with the party to win its support for the Clean Energy Future Package.

Ms Gillard stressed that her dealings with the Greens had culminated Tuesday when the carbon tax was approved by the Parliament and gave assurance that no future discussions will be held with Green leaders regarding the expansion of the government's new energy policy.

"There will be a diverse range of energy sources. We believe coal-seam gas will be part of the energy mix of the future ... The scheme that's gone through the parliament will be the scheme," the Prime Minister was quoted by media reports as saying.

Also, Climate Change Minister Greg Combet recalled that the Greens leadership were fully aware that the government was adamant on allowing the forces of market mechanism to play out its role in determining the country's environmental and energy policies.

"The Greens' policy was for 100 per cent renewable energy while the government has put together a package that would allow investors to make the decisions on the use of fuel sources or renewable technology based on the market mechanism," Combet reminded Milne.

In a statement, Greens environment spokeswoman Larissa Waters clarified that the party was not shifting its gear at all in terms of articulating its stand over Australia's preferred source of energy in the decades ahead.

Waters, however, asserted that "we will continue to push for renewables to power Australia and for us to be exporting that technology to the world."

"There have been studies done that show Australia could be powered by 100 per cent renewables within a decade using today's technology. We have the ability; we simply lack the political will," the Greens senator added as reported by The Australian.

The party's new stance, however, was scored by the country's business community, which also underscored that Greens' policies have considerably hurt the domestic economy.

Australian Chamber of Commerce and Industry economics director Greg Evans rejected the Greens suggestions that the nation would remain economically viable while relying on renewable energy full time.

"The Greens' aspiration for 100 per cent renewable energy as soon as possible is plainly a ludicrous pipedream ... and such claim shows the carbon price was just the beginning of the crusade and they will continue to advocate highly interventionist, costly and extremely damaging policy responses," Evans pointed out.
