ذهب مع الريح

كوبنهاجن – ان الجهود للحد من الاحتباس الحراري قد ادت الى ايجاد دافع قوي في العالم للاستفادة من الطاقة المتجددة وكنتيجة لذلك فإن استخدام تورينات الرياح قد ازداد بمقدار عشرة اضعاف خلال العقد الماضي حيث يشار الى الطاقة التي يتم توليدها عن طريق الرياح على انها اكثر وسائل الطاقة المتجددة فعالية من حيث التكلفة . لقد ذكرت كوني هيدجارد مفوضة الاتحاد الاوروبي للعمل المتعلق بالمناخ:

" يجب على الناس ان يؤمنوا ان الطاقة التي يتم توليدها عن طريق الرياح رخيصة للغاية ".

ان هناك الكثير من الشكوك حول هذا الادعاء اعلاه فالطاقة المرتبطة بالرياح هي ارخص من غيرها من وسائل الطاقة المتجددة والتي تنعدم فعاليتها بشكل اكبر من طاقة الريح مثل الطاقة الشمسية وطاقة المد البحري والايثانول ولكن الطاقة المرتبطة بالرياح تفتقد الى التنافسية بشكل كبير ولو كانت تنافسية لما اضطررنا لصرف اموال ضخمة من اجل دعمها .

  3. Murdoch's Last Stand?

    Rupert Murdoch’s sale of 21st Century Fox’s entertainment assets to Disney for $66 billion may mark the end of the media mogul’s career, which will long be remembered for its corrosive effect on democratic discourse on both sides of the Atlantic. 

    From enabling the rise of Donald Trump to hacking the telephone of a murdered British schoolgirl, Murdoch’s media empire has staked its success on stoking populist rage.

    The Dangerous Delusion of Price Stability

    Since the hyperinflation of the 1970s, which central banks were right to combat by whatever means necessary, maintaining positive but low inflation has become a monetary-policy obsession. But, because the world economy has changed dramatically since then, central bankers have started to miss the monetary-policy forest for the trees.

  5. Harvard’s Jeffrey Frankel Measures the GOP’s Tax Plan

    Jeffrey Frankel, a professor at Harvard University’s Kennedy School of Government and a former member of President Bill Clinton’s Council of Economic Advisers, outlines the five criteria he uses to judge the efficacy of tax reform efforts. And in his view, the US Republicans’ most recent offering fails miserably.

But ensuring that those changes are positive – helping to fight tumors and mosquito-borne illnesses, for example – will require scientists to apply the utmost caution.
