With the Paris climate talks just around the corner it is timely to consider what effective policies to cut emissions might look like. Nationalisation and direct public investment are key policies that have historically been “bread and butter” political demands both for socialists and for the more radical voices within social democratic parties. Climate activists from the Greens and Labor Environment Action Network should revisit these ideas, as they are a useful alternative to the dead end that is carbon trading. Direct public investment

Right now, there is an opportunity to slash Australia’s carbon emissions by 5 million tonnes a year in one stroke. The city of Port Augusta in South Australia has all the right conditions to make it Australia’s first baseload renewable energy hub. The two coal-fired power stations at Port Augusta are getting old. Industry experts say they may be forced to close as soon as 2015.

More than 300 people of all ages gathered in Adelaide on September 24 calling for concentrating solar thermal (CST) technology to replace Port Augusta’s ageing coal fired power stations. The action was organised by several environment groups, including the Australian Youth Climate Coalition, the Climate Emergency Action Network, the Socialist Alliance, Resistance and the Young Greens. The crowd met in Adelaide’s Rymill Park and took to the streets in a colourful, rhythmic parade, featuring a moving solar thermal tower.
