Wind energy produces costly, intermittent, unpredictable electricity. But Government subsidies and mandates have encouraged a massive gamble on wind investments in Australia – over $7 billion has already been spent and another $30 billion is proposed. This expenditure is justified by the claim that by using wind energy there will be less carbon dioxide emitted to the atmosphere which will help to prevent dangerous global warming.
Incredibly, this claim is not supported by any credible cost-benefit analysis – a searching enquiry is well overdue. Here is a summary of things that should be included in the analysis.
Firstly, no one knows how much global warming is related to carbon dioxide and how much is due to natural variability. However, the historical record shows that carbon dioxide it is not the most important factor, and no one knows whether climate feedbacks are positive or negative. Also, in many ways, the biosphere and humanity would benefit from more warmth, carbon dioxide and moisture in the atmosphere.
However, let’s assume that reducing man’s production of carbon dioxide is a sensible goal and consider whether wind power is likely to achieve it. To do this we need to look at the whole life cycle of a wind tower. Continue reading here…..
