The financial benefits of these various low-carbon support mechanisms accrue either to the big utilities, in the case of offshore wind and nuclear, or to wealthy investors, in the case of onshore wind, solar and the rest. The cost is borne by the ordinary energy consumer.

When Huhne claims his policies will protect consumers from undue price rises on the international gas and oil markets he commits the cardinal sin of believing price forecasts that suit his argument. In fact the global gas price is likely to fall under pressure from growing competition across Europe, abundant supplies of liquefied natural gas, and the promise of shale gas in the US. Huhne is determined to talk down the potential of shale, but all geologists know that it is a long-term game changer.

And if that depresses you, remember this: Britain met its Kyoto target because of the dash for gas.
