Greens Leader Christine Milne says Clive Palmer's backflip on supporting the Renewable Energy Target on ABC's RN Breakfast this morning shows the Palmer political party cannot be trusted and will say and do anything on a whim.

"The Palmer political party is saying whatever it thinks it needs to for electoral gain. This backflip is disgraceful and will sound the alarm not only in Western Australia but with everyone who supports renewable energy," Senator Milne said.

The Australian Greens say the Abbott government's RET review is a thinly veiled attack on solar and wind energy in favour of coal energy.

"Reducing our clean energy quota will not make electricity cheaper, it will just make it dirtier," Greens Leader Christine Milne said.

"All this hyperventilating we are seeing about energy prices is despite the fact that renewable energy has actually driven down wholesale prices in Australia.

Greens Senator for WA Scott Ludlam, former Australian Greens Leader Bob Brown and NZ Greens spokesperson for Energy Gareth Hughes MP united with key members of the WA renewable energy industry today to warn against an attack on renewable energy policy following Saturday's Federal election.

"Every time Tony Abbott opens his mouth he is costing WA jobs and investment," Scott Ludlam, Greens Senator for Western Australia said at a joint press conference.

The Australian Greens will today launch a plan for energy and water efficiency upgrades to social housing that will improve the lives of one million Australians.

Greens housing spokesperson Senator Scott Ludlam said ‘Repowering Social Housing' will bring down the cost of living for those who need it most.

"The Greens' plan will put solar panels on the roof of every social housing home, will cut power bills for those who need it most, and will improve quality of life for the one million Australians living in social housing," said Senator Ludlam.

Greens Senator for Western Australia Scott Ludlam was in Collie today talking with locals about the Greens' plans for Collie as a renewable energy generation hub.

Senator Ludlam, who earlier this year released Energy 2029 - a costed, technical plan for how WA's main electricity grid could switch to 100% renewable energy generation - said Collie should be one of five regional Renewable Energy Zones as it had key attributes that made it the right place to generate renewable energy.

"Tony Abbott has cast huge uncertainty over the whole renewable energy industry and if he gets control of both houses of Parliament he will kill clean energy investment in its tracks," Australian Greens Leader Senator Christine Milne said.

"People have a clear choice they can vote for the Greens and a renewable energy future or they can vote for Tony Abbott and the ongoing support of coal fired generation and gas.

Greens Senator for WA Scott Ludlam will join protestors rallying in Fremantle tomorrow - Saturday 17 August - against the controversial method of underground gas extraction known as fracking.

"The WA Parliamentary Inquiry into hydraulic fracturing or ‘fracking' announced this week is a good idea given the Barnett Government's plans to massively ramp up this industry in the Mid-West, Kimberley and elsewhere in WA," Senator Ludlam said.

Debate around gas and oil development and the implications of Labor's Northern Territory tax plan misses the main question about Western Australia's energy future, The Greens said today.

"While the Premier attacks the Prime Minister for supposedly threatening his gas ambitions, and Kevin Rudd talks about making Perth an oil and gas headquarters, both Labor and the Liberals are ignoring Western Australia's huge solar potential," said Senator for Western Australia Scott Ludlam.

The Australian Greens have welcomed the WA Government's more reasoned approach to solar feed-in-tariffs, while warning Mr Barnett must recognise that renewable energy is the way forward for WA.

"Congratulations to the thousands of Western Australians who stood up to Mr Barnett and made him realise that he couldn't break a promise to electricity customers," Greens Senator for WA Scott Ludlam said.

"Now it's time for Mr Barnett to see the bigger picture.

Senator for Western Australia Scott Ludlam has taken a strong stand against the Barnett Government’s solar swindle today, launching The Greens’ plan for an Energy Savings Agency to deliver Fair Pay for Solar in WA.
