The technical problem for Australia is that insufficient development of geothermal and solar power (ESAA 2007), and limited opportunities for more hydropower (Australian Government 2004), requires a significant reliance on wind energy as a viable and proven technology. If a near total reliance on wind resulted over the next decade at least, this would imply increasing Australia’s amount of some 563 wind turbines (comprising 42 wind farms) to some 4500 (ESAA 2007), which poses some difficulties construction-wise. Even if this latter figure turns out to be an over estimate, by 2007, a further 87 wind farms were proposed, and were either at the planning or approvals stage (Tennant-Wood 2007), an amount that in itself constitutes a major expansion that will increase with the new Renewable Energy Target (RET) to be operationalised in 2010.
