Mark Landler. “Sweden Turns to a Promising Power Source, With Flaws”. New York Times. November 23, 2007 – In Denmark, which pioneered wind energy in Europe, construction of wind farms has stagnated in recent years. The Danes export much of their wind-generated electricity to Norway and Sweden because it comes in unpredictable surges that often outstrip demand.
In 2003, Ireland put a moratorium on connecting wind farms to its electricity grid because of the strains that power surges were putting on the network; it has since begun connecting them again.
Matthew Wald. “Wind Energy Bumps Into Power Grid’s Limits”. New York Times. 26 Aug. 2008 – When the builders of the Maple Ridge Wind farm spent $320 million to put nearly 200 wind turbines in upstate New York, the idea was to get paid for producing electricity. But at times, regional electric lines have been so congested that Maple Ridge has been forced to shut down even with a brisk wind blowing.
That is a symptom of a broad national problem. Expansive dreams about renewable energy, like Al Gore’s hope of replacing all fossil fuels in a decade, are bumping up against the reality of a power grid that cannot handle the new demands.
The dirty secret of clean energy is that while generating it is getting easier, moving it to market is not.
