Yesterday’s Commentary suggested that Turnbull’s attack on the role played by Shorten as head of the AWU was no more than a start in restoring the Coalition’s polling. Today, Andrew Bolt argues that such a strategy is counter-productive (see article below). He rightly points out that Turnbull’s existing policy on the renewable target will still produce bad results in the form of higher electricity prices – and no benefit in terms of reducing world temperatures. In fact, the current target of 23 per cent by 2020 would not only add further to electricity prices even if it were to be achieved, which is widely regarded as highly unlikely. It would also mean that Australia would be imposing on itself higher costs than in most other countries at a time when US President Trump is likely to include in his policy the abandonment of usage of renewable, or their minimal use.
