Denmark's wind energy failure

OK. That's been done — by the establishment think tank CEPOS, and you can read it here. The answer is that the president's (repeat) claim that "Denmark produces almost 20 percent of their electricity through wind power" is false. Denmark actually produces much less of its own electricity from wind, as low as 4 percent depending on the year, with the recent average of 9.7 percent. This despite a massive buildout of what they flatteringly call the "wind carpet," on some of the most hospitable terrain for wind power in the world.
It is also in return for its households paying the highest eletricity rates in Europe. With a substantially lower per-capita energy use. That means, to get half of what Obama seeks, the U.S. would have to carpet itself twice over — which means lots of windmills where birds fly and Kennedys live — and pay Danish-style rates.
Oh. Wait. That still won't do it. Apparently Denmark's experience isn't even scalable to Scanadanavia. It turns out that, if the Norwegians and Swedes tried to replicate Denmark's expensive folly, well, it would blow the system up. Here's why. Denmark took advantage of long-since-paid-for interconnectors between Jutland and Norway, and the island on which Copenhagen sits and Sweden. It made a political decision that windmills would be their "national champion" industry, and as you will hear to no end throughout the Copenhagen COP, a big part of their national identity. So they built a lot of windmills, and started a mythology.
