vestas produced green jobs before they were trendy. >> we learned that energy dependence is somethingou should take very, very seriously. >> vestsa' ceo learned that the danes get almost 30% of their electricity from the wind, more than any other developed nation. by 2020, they pledge to get half of their electricity from wind power. and by 2050, they promise to be completely fossil fuel-free. >> it's not about what is possible from a technological point of view, it's all down to leadership and determination. >> samso is a sign of what's possible. it's a sleepy island between the north sea and the baltic sea where you might see as many cows as people. but don't let the rustic setting fool you, the island is on the cutting edge of energy efficiency. all of its electricity comes from the wind and overall samso actually has a negative carbon footprint. farmers like yan are clean energy entrepreneur, owning a share of the island's wind turbines. >> the wind turbines on the sea they produce 18 million kilowatt so that's the biggest export from the island that's electricity. >> the u.s. cou

he also points out that vestas has run into trouble. it plans to cut number 4,000 jobs in 2012, including one-fifth of its u.s. workforce and wind power overall, he points out, is still more expensive than the cheapest fossil fuels. >> as long as it's not competitive, i still think we should say let's invest more in getting the next generations of wind turbines to be cheaper rather than putting up lots and lots of them that we know are inefficient right now. >> but people say the only way you get the cost curve down is deploying large amentsz of existing tech nothing in scale. >> it's still more expensive even after we produce lots of it. >> another big challenge, storing wind power. to use when the wind isn't blowing. in fact, all of the world's current battery capacity can store only ten minutes' worth of the world's annual energy demand according to bill gates. one idea, take the excess energy that you can't store from the wind turbines and use it to charge the batteries for electric cars. one company called better place already has

the united states and downgrades of demand and earnings from alcoa and chevron are depressing and vestas and that's not even helped by the latest beige book report which showed that had ten out of twelve fed districts showed moderate growth in august and september over in europe we're also seeing a pretty gloomy mood at the close that says uncertainty. the remains of the spade and greece and in the currencies market we're seeing a drop of the dollar against the euro deepening after that beige book reports but that's actually a positive sign and the russian ruble as you can see that was stronger against both currencies the russian market was also down despite high oil prices they would take you know for that pessimism from elsewhere. and i'm afraid that's all we have time for at this hour coming up next on out so we talked to andy greenberg from forbes magazine and he says that despite the u.s. war on whistle blows truth advocacy is on the rise to say. this machine kills secrets is the title of a new book that chronicles the history and future of information leaks ranging from the pentago
