اضاعة الاموال على الرياح

برلين- عندما ننظر في التغير المناخي فإن معظم الناس يعتقدون ان توربينات الرياح والالواح الشمسية تشكل جزءا كبيرا من الحل ولكن خلال السنوات الخمس والعشرين القادمة فإن مساهمة الطاقة الشمسية وطاقة الرياح في حل المشكلة سوف تكون ضئيلة للغاية والتكلفة ستكون ضخمة.

تقدر وكالة الطاقة الذرية ان حوالي 0،4 من الطاقة العالمية الان تأتي من الطاقة الشمسية وطاقة الرياح وحتى في سنة 2040 ومع تطبيق كل الحكومات لوعودها الخضراء فإن الطاقة الشمسية وطاقة الرياح سوف تشكل 2،2% فقط من الطاقة العالمية .ان هذا يعود جزئيا لكون الطاقة الشمسية وطاقة الرياح تساعد في تخفيض انبعاثات غاز الدفيئة فقط من توليد الكهرباء والذي يشكل42% من الاجمالي ولكن ليس من الطاقة المستخدمة في الصناعة والنقل والمباني والزراعة.

لكن السبب الرئيسي وراء عدم اعتبار القوة الشمسية وقوة الرياح حل رئيسي للتغير المناخي ينبع من عائق لا يمكن التغلب عليه : نحن بحاجة للطاقة عندما لا تكون الشمس ساطعة وعندما لا تهب الرياح .

    Populist Plutocracy and the Future of America

    • In the first year of his presidency, Donald Trump has consistently sold out the blue-collar, socially conservative whites who brought him to power, while pursuing policies to enrich his fellow plutocrats. 

    • Sooner or later, Trump's core supporters will wake up to this fact, so it is worth asking how far he might go to keep them on his side.

    The Man Who Didn’t Save the World

    A Saudi prince has been revealed to be the buyer of Leonardo da Vinci's "Salvator Mundi," for which he spent $450.3 million. Had he given the money to the poor, as the subject of the painting instructed another rich man, he could have restored eyesight to nine million people, or enabled 13 million families to grow 50% more food.
