Reducing our coal dependence

According to the coal industry, greenhouse gases generated from coal through such activities as mining and power generation globally contribute around 25 per cent to the enhanced greenhouse effect. In Australia, around 90 per cent of coal's greenhouse gas emissions arise from power generation.

This is why Australia’s dependence on coal is alarming – a dependence that was highlighted earlier this week.

First, in New South Wales, we have the state government giving the green light to two 2000- megawatt power stations at Mount Piper, near Lithgow, and Bayswater, near Muswellbrook in the Hunter. This has raised concerns about an even bigger increase in greenhouse gas emissions, especially if coal is used. Even if both power stations use gas, emissions will rise by about 13 million tonnes, a 20 per cent increase. There are claims that this will ruin the state’s renewable energy industry.

There is a similar situation in Victoria, where brown-coal-fired electricity is to continue operating for decades with the announcement of a long-term power deal for Alcoa's controversial aluminium smelters. The implications for greenhouse gas emissions and the future of the renewable energy industry are immense. As Environment Victoria spokesman Mark Wakeham told the Sydney Morning Herald:
“In a time of climate change it is insane to power aluminum smelters with brown coal. Locking this behaviour in until 2036 defies belief.”
