Excerpt from Redneck USA by Dominik Lawson UK Sunday Times
"...Nevertheless, there is one great merit in being a follower rather than a leader in renewable energy: we can see how other European countries have fared in the experiment. Germany has long been subsidising wind power to the extent of almost €5 billion a year. Yet recent German Green party internal e-mails leaked to Der Spiegel magazine show this has not led to a reduction of a single gram of CO2 emitted on the continent of Europe. The much-vaunted emissions trading system is one reason: Germany’s unused certificates were snapped up at negligible cost by coal producers in countries such as Poland and Slovakia, which were thus able to increase their output of greenhouse gases.
There is a second reason, which would remain even if the European emissions trading system were to be scrapped. Because the wind blows intermittently, and may be at its calmest at times of freezing weather, Germany has not been able to close a single one of its conventional power stations, despite its vast investment in wind power.
Indeed, Paul Golby, who runs the British operations of E.ON, Europe’s biggest wind-power producer, has told the government that a 90% fossil fuel or nuclear back-up will be needed for any of the National Grid’s future wind-power capacity. As Martin Fuchs, his German boss, pointed out: “The wind, sadly, does not blow where large quantities of power are required . . . on September 12 last year wind power contributed 38% of our grid power requirements at all times, but on September 30 the figure went down to 0.2%.”
The powerful wind-turbine lobby in Germany constantly harps on about the number of jobs “created” by its subsidised investment, quite ignoring the number of jobs destroyed by high-cost energy, or indeed the greater number of jobs that could be created if the same amounts were invested in more profitable activities. This is why the Bremen Energy Institute argues that “wind energy macro-economically has a negative employment impact”.
Given the run-down state of our conventional generating capacity, it is easy to see that the government’s suspiciously round number of a “£100 billion” expenditure on installing 7,000 offshore steel structures, each the height of Blackpool Tower, at a projected rate of more than two every working day over the next decade, does not begin to cover the real cost. This is why the overall price of wind energy is a multiple of that incurred by nuclear power, which is equally carbon-free but does not appeal to the moral vanity of politicians..."
