We’re shocked: disturbing reports today* revealed that AGL plans to charge up to an extra $434 for new solar meters in the ACT and NSW. These unfair charges will make it harder for thousands of households to take control of their electricity bills and go solar.
SIGN AND SHARE: Tell the NSW and ACT energy ministers to stop these outrageous and unfair charges.
Recent polling shows that 71% of people think Australia should put more emphasis on solar power ahead of all other forms of electricity generation**. What’s more galling is that only last month, AGL launched extensive TV and digital advertising pushing its expertise in solar products with the tagline “Not all solar is created equal” – now they want to make it harder for Australians to go solar!
AGL has actively campaigned to cut the Renewable Energy Target and is now putting the proverbial boot in to everyday consumers by ratcheting up these enormous charges.
These increases will create a huge disincentive to the many thousands of people who want to go solar in New South Wales and the ACT – not to mention the huge precedent this could set for other big power companies to try and charge solar owners more. People switching to solar are making the sensible decision to generate cheap, clean electricity from the sun. This decision should be easy, but AGL wants to price ordinary people out of the solar market.
For a fair, sun-powered country,
Dan, Campaigns Director

Dear friends,
Pope Francis just made history. He’s taken the climate debate to a new level — more than an environmental issue, he’s declared a clear moral imperative to protect our planet, and it’s front page news.
Our Prime Minister has made dozens of excuses not to act on climate change, but a call from the head of his own church could be the tipping point. And it can’t come soon enough — Abbott’s deciding Australia’s climate targets right now!
Let’s help our PM ‘see the light’ on climate. If we flood the PM’s office with calls while the encyclical is in the headlines, we can amplify Pope Francis’ message and get Abbott to commit to targets worthy of the Pope’s call.
Phone the PM’s office now:
(02) 6277 7700
Here are some talking points to help with your call. Don’t forget to let the PM’s office know if you’re Catholic!
Remember to be polite and succinct — the PM’s staff will take a note of your message and pass on your comments.
Tell us how the call went:
https://secure.avaaz.org/en/pope_encyclical_abbott_call_in/?bhPqncb&v=60566
The Pope’s encyclical is a demonstration of faith, love and hope for a brighter future in which we all act to protect our climate. There’s still a chance for Australia to show the leadership we’re capable of and present strong targets at the Paris summit this year.
Make a call to ensure the messages from the Pope’s encyclical reach the politicians that are deciding our climate targets right now:
(02) 6277 7700
Our movement is a source of determination and inspiration in the fight against climate change. We’re always looking for key moments to shift the dial towards a pollution free future in Australia and around the world. This is a moment — let’s seize it together.
With hope,
Emily, Oli, Nic, Iain, David, Mais and the whole Avaaz team

Boulder, Colorado, USA –The “wheat belt” and “gold fields” of southern Western Australia are associated with a regional acid saline groundwater system. Groundwaters hosted in the Yilgarn Craton there have pH levels as low as 2.4 and salinities as high as 28%, which have greatly affected bedrock and subsurface sediments. This is manifested above ground as hundreds of shallow, ephemeral acid saline lakes.
In the June issue of GSA Today, Kathleen Benison of West Virginia University and Brenda Bowen of the University of Utah write that the limited volume of groundwater, in combination with its acidity, salinity, and high concentrations of some metals, make southern Western Australia a difficult place for human habitation.
The overarching question addressed by this study is “How did the extreme acidity form here?” The authors discuss the combination of processes that make up these shallow lakes and the groundwater that feeds them, which is not only dependent upon the host rock lithology, mineralogy, climate, weathering, organisms, and time, but also on mining and agriculture in the region.
Benison and Bowen write, “In the twentieth century both agriculture and mining had local influence on acid brine groundwater. A government-sponsored effort to turn the semi-arid eucalypt forests of inland southern Western Australia to crop and ranchland promoted the deforestation of the ‘wheat belt’ region. With fewer trees to soak up the acid saline groundwater, the water table rose. Ranchers realized that cattle and sheep did not thrive with acid brines. Farmers found the only successful crops were grown high above the water table and irrigated with desalinized seawater piped a distance of hundreds of kilometers.”
Mining efforts have also used desalinized seawater pipelines. Both mining and agriculture import fresher water to the groundwater system and may be responsible for changing the volume of groundwater slightly, as well as potentially causing dissolution of some subsurface halite and other chemical sediments, and, perhaps in turn, increasing groundwater salinity.
Looking forward at further research areas, the authors write, “Extreme acid brine environments similar to those in southern Western Australia have been recognized on Earth and Mars. In particular, some mid-Permian continental environments hosted extremely acid saline lakes and groundwaters that deposited redbeds and evaporites. The temporal and geographic extent of these Permian acid brine settings, and their relationship to Permian climate change and the end Permian mass extinction, are open scientific questions. Understanding the origin, evolution, and maintenance of modern natural acid brine environments may lead to more informed paleoenvironmental, paleoclimatic, and paleobiological interpretations about ancient acid brines.
