Excerpt from The Monthly re the carbon tax

Let’s be clear: this is the single biggest reason power prices have skyrocketed. According to the federal treasury, 51% of your electricity bill goes towards “network charges”. The carbon tax, despite relentless propaganda to the contrary, is small beer, comprising just 9%. The rest of your bill is carved up between those companies that actually generate your electricity (20%) and the retailers who package it up and sell it to you (20%). The Renewable Energy Target is such a small cost impost, the treasury’s analysis doesn’t even include it; the Australian Energy Market Commission says it makes up around 5%. 
Thanks to the networks’ infrastructure binge, we now pay some of the highest prices in the developed world. The impact has been felt most keenly in New South Wales and Queensland, where the networks are government owned and network charges have accounted for two thirds of the price increases. 
For a Coalition intent on destroying the carbon tax, the price hikes have been a gift – “proof” that the carbon tax is as ruinous as they predicted. Chris Dunstan, from the Institute for Sustainable Futures, thinks that what the networks have done over the past five years may actually be the secret to Tony Abbott’s success. “If electricity prices hadn’t doubled,” he says, “the carbon tax would not have been anything like the issue it was.”
