Policy for reducing carbon dioxide emissions now appears to be double-barrelled with a target for renewable sources for electricity generation with government subsidies and a carbon tax in the form of an emissions trading scheme. Neither approach appears to be realistic, possible or even plausible.
The Federal Government has a target of 20 per cent renewable electricity by 2020. This requires about 6,000MW of additional deliverable power for a projected total energy demand of 260,000GWh in 2020.
It is difficult to imagine any carbon free technology readily deployable and able to provide this except for nuclear power and wind. Since the government will not consider nuclear power, wind power is the technology of choice.
