Wind Energy Is Extraordinarily Expensive And Inefficient

Quem diria ... [bolds meus]

London, 6 August: The Global Warming Policy Foundations has warned policy makers that wind energy is an extraordinarily expensive and inefficient way of reducing CO2 emissions. In fact, there is a significant likelihood that annual CO2 emissions could be greater under the Government’s current wind strategy than under an alternative Gas scenario.

[...]

The necessary investment for this Wind scenario would amount to about £124 billion. The same electricity demand could be met from 21.5 GW of combined cycle gas plants with a capital cost of £13 billion – the latter option is cheaper by an order of magnitude.  According to Professor Hughes, “the average household electricity bill would increase from £528 per year at 2010 prices to a range from £730 to £840 in 2020 under the Mixed Wind scenario. These figures amount to increases of 38% to 58% in the average household bill relative to the baseline under the Gas scenario. The equivalent ranges for the other scenarios are 29-46% for the More Onshore Wind scenario and 40-62% for the Future Offshore Wind scenario."

 "The key problems with current policies for wind power are simple. They require a huge commitment of investment to a technology that is not very green, in the sense of saving a lot of CO2, but which is certainly very expensive and inflexible. Unless the current Government scales back its commitment to wind power very substantially, its policy will be worse than a mistake, it will be a blunder,"  Professor Hughes said.
