Why wind is cutting energy costs
The most common critique of wind energy, and renewables in general, in the mainstream media and anywhere the issue is discussed is that it is expensive.
The problem is, this is only half true. Or at least, it only tells half the story. While the levelised cost of energy from wind farms is higher than that of baseload coal and gas, the deployment of wind energy here and overseas is having a surprising impact on energy market prices: it is causing them to fall.

The true productivity of solar PV A review has found that the government's carbon price negotiations are founded on emissions data for solar PV that may underestimate its cost effectiveness by up to a factor of 10.
The Australian PV Association (APVA) has done analysis of the recent Productivity Commission report being used by the government, Greens and independents in negotiations about a carbon price. The APVA findings show that solar PV could be between four and 11 times more effective as a way to cut greenhouse pollution than the Commission has calculated.
The Commission claims that the cost of emissions reduction achieved via solar PV is $432-$1043/tonne CO2. According to the APVA, the true figure is $90-$95/t CO2, depending on the installation location. This discrepancy is explained by the following errors in the Commission report:
