Today marks a year since the Abbott government shattered investor confidence by launching its unnecessary and ideological review of the Renewable Energy Target, and Greens Leader Christine Milne says its time for the uncertainty to end.

"The Liberals need end their attack on the Renewable Energy Target and stop destroying jobs to protect their mates at the big end of town," said Senator Milne.

Senator Ricky Muir has this afternoon said in the Senate he will support exemptions for heavy industry and the inclusion of electricity generation from burning native forests within the Renewable Energy Target.

"Exemptions for heavy industry and inclusion of energy generated from burning native forests in the Renewable Energy Target would be a disaster. It would do even more to destroy confidence in Australian clean energy," Greens Leader Christine Milne said.

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.

Hydro Tasmania’s record profit announcement today highlights what a fantastic boost the carbon price and Renewable Energy Target (RET) have been for Tasmania, Australian Greens Leader Christine Milne said.

“Hydro Tasmania has made a record profit thanks to the carbon price and RET, but the Abbott government has deliberately destroyed future profit potential,” Senator 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. 

Renewable energy is pushing the price of electricity down. Palmer’s plan to cut the RET is nothing short of a hand out for big business, payed for by households and small business.

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.
