How Windmills as Wide as Jumbo Jets Are Making Clean Energy Mainstream

At the northern end of Denmark’s Jutland peninsula, the wind blows so hard that rows of trees grow in one direction, like gnarled flags.

The relentless weather over this long strip of farmland, bogs and mud flats — and the real-world laboratory it provides — has given the country a leading role in transforming wind power into a viable source of clean energy.

After energy prices spiked during the 1973 oil crisis, entrepreneurs began building small turbines to sell here. “It started out as an interest in providing power for my parents’ farm,” said Henrik Stiesdal, who designed and built early prototypes with a blacksmith partner.

The initial windmills made by small operations had quality problems. Blades — then just 15 feet in length — would break or fall apart.

Now, they are giants, made by global players pulling off enormous feats of engineering.

There is nothing to see when I click the link other than a pop-up from the NYT trying to sucker me out of ten bucks.

Dean,

I just checked the link and I saw the article. You are only allowed 10 free articles a week at the NYT, so I guess you went over your limit. 

Bob, that is something to keep in mind. You might want to post more of the article, since I run into this issue a lot, too.

Perrie,

I don't see any way to seed the videos, which are the coolest part...

Yes I see that... the NYT is very sneaky about hiding their codes so you have to pay for the service. You can use the permalink located on the upper right corner, after you scroll a bit.

I don't see the link you're talking about, but I'm a subscriber and I'm on an android tablet.
