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 .

    The Next Battle in China’s War on Corruption

    • Chinese President Xi Jinping knows well the threat that corruption poses to the authority of the Communist Party of China and the state it controls. 
    • But moving beyond Xi's anti-corruption purge to build robust and lasting anti-graft institutions will not be easy, owing to enduring opportunities for bureaucratic capture.

    Putting Europe’s Long-Term Unemployed Back to Work

    Across the European Union, millions of people who are willing and able to work have been unemployed for a year or longer, at great cost to social cohesion and political stability. If the EU is serious about stopping the rise of populism, it will need to do more to ensure that labor markets are working for everyone.

    A Belt and Road for the Americas?

    In a time of global uncertainty, a vision of “made in the Americas” prosperity provides a unifying agenda for the continent. If implemented, the US could reassert its historical leadership among a group of countries that share its fundamental values, as well as an interest in inclusive economic growth and rising living standards.

    How Best to Promote Research and Development

    Clearly, there is something appealing about a start-up-based innovation strategy: it feels democratic, accessible, and so California. But it is definitely not the only way to boost research and development, or even the main way, and it is certainly not the way most major innovations in the US came about during the twentieth century.

    Preparing for the Trump Trade Wars

    In the first 11 months of his presidency, Donald Trump has failed to back up his words – or tweets – with action on a variety of fronts. But the rest of the world's governments, and particularly those in Asia and Europe, would be mistaken to assume that he won't follow through on his promised "America First" trade agenda.
