Wind power is unreliable and requires back-up gas power stations to maintain a consistent electricity supply, a recent think-tank study found.
The study, written by economist Ruth Lea from the think-tank Civitas, uses UK government commissioned estimates of the cost of electricity generation to calculate the most cost-effective technologies.
Gas-fired power is the most cost-effective in the short term, while nuclear power stations become the most cost-efficient in the medium term, more than twice as cost-effective as wind.
The report concludes:
“Wind power is expensive and yet is not effective in cutting CO2 emissions."
"If it were not for the renewables targets, wind power would not even be entertained as a cost-effective way of generating electricity or cutting emissions. The renewables target should be renegotiated with the EU.”
The study attacks UK government claims that wind power is one of the more cost-effective means of generating power. In fact, it says, it is “unreliable and requires conventional back-up capacity”.
The report also says wind power, backed by conventional gas-fired generation, can emit more CO2 than the most effective gas turbines running alone.
No point in wasting my breath telling Julia Gillard and Bob Brown that Wind Power is useless, but Tony Abbott should announce that the coalition no longer supports the government’s insane 20% renewable energy target. Rescinding it and the Carbon (Dioxide) Tax is the only way to ensure retail electricity prices cease their stratospheric rise.
