Responding to the decision by Keppel Prince to mothball its entire wind turbine division and lay off 100 workers, Greens Leader Christine Milne says the Abbott government has taken a wrecking ball to the industry that holds the best hope of providing future jobs and investment in Australia.

"The Abbott government is destroying jobs now and Australia's best hope of future investment beyond the mining boom in order to protect its billionaire mates in the coal industry," Greens Leader Christine Milne said.

Palmer wants to cut the Renewable Energy Target (RET) by 5% and let big business off the hook.

The Palmer United Party are asking the Government to give the aluminium industry a 100% exemption from the RET.

The aluminium industry is currently required to source just 10% of their electricity from clean energy sources. Palmer is asking that this be reduced to zero. 

At Parliament House this morning Australian Greens Leader Christine Milne stood with students studying for clean energy jobs, urging the other parties not to help Tony Abbott degrade the Renewable Energy Target.

"The Renewable Energy Target must not be tampered with. The only compromise should be getting the Abbott government to move with the times and start shutting down fossil fuels," said Senator Milne.

Australian Greens Senator for South Australia Penny Wright says Prime Minister Tony Abbott must end the uncertainty around the future of the Renewable Energy Target, as South Australia announces plans to raise its target to 50 per cent.

"The Renewable Energy Target is cutting pollution, creating jobs and will bring power bills down," Senator Wright said.

South Australia stands to lose almost $3 billion of investment if Tony Abbott dumps the Renewable Energy Target, says SA Greens Senator Penny Wright.

New figures compiled by Senator Wright show South Australia will suffer more than any other state if the popular RET is scrapped.

“South Australia cannot afford to lose the RET,” Senator Wright said. “If the RET goes, $2.9 billion of investments in clean energy will go overseas instead.

Australian Greens Leader Christine Milne says the Abbott government has today admitted it is undermining renewable energy to protect the old coal-fired generators, after comments by Industry Minister Ian Macfarlane on morning radio.

"The Industry Minister has belled the cat on the RET review. He's made it clear this attack on renewable energy is nothing more than a cynical move to prop up old coal-fired power stations," Senator Milne said.

The Australian Greens say it's no surprise that a review led by a climate sceptic has trashed the Renewable Energy Target, saying both options the report presents will destroy renewable energy in Australia.

"I'm glad this dangerous and ignorant report is finally public, so everyone can see it for the climate denier drivel it is. The outcome was determined long ago," said Greens Leader Senator Christine Milne.

"It's now time to give the industry certainty by retaining and expanding the Renewable Energy Target.

Australian Greens Leader Christine Milne says the Renewable Energy Target has been a major contributor to cutting pollution and energy costs, and must not be scaled down or abandoned.

"Tony Abbott wants to destroy jobs, destroy investment and make power more expensive for consumers all because he wants to protect the old coal-fired generators and gas companies," said Senator Milne.

"Tony Abbott's mates in the big end of town, in the coal industry in particular, can't cope with the competition from renewable energy.
