什么能源短缺?

瑞士马蒂尼——如果我们能够捕获并利用短短两分钟内照射到地球上的太阳能量,就足以为我们的汽车加油、为我们的建筑提供照明、采暖以及满足整整一年其他所有的用电需求。简单地说,我们人类并没有面临能源短缺。我们所面临的是捕获能量并将其提供给消费者的技术难题;投资于更好的储存方法是解决这一难题最有效的方式之一。

当今世界的许多问题都可以追溯到能源应用领域,从石油供应引发的冲突、温室气体排放引发的担忧到因电力短缺或停电造成的生产率和产量损失。在世界许多最贫困地区,能源的缺乏仍在扼杀经济发展。全球范围内超过13亿人还没用上电;大约26亿人还没用上现代烹饪设施。上述人口中超过95%居住在撒哈拉以南非洲或亚洲发展中国家,并且84%生活在农村地区。

比方说,在尼日利亚最近一次总统选举前夕,一位妇女被问及她想要候选人为她做什么。她只回答了一个词:“灯”。电力这种最基本的商品能够让她继续工作、让她的孩子继续学习。

    Angela Merkel’s Endgame?

    The collapse of coalition negotiations has left German Chancellor Angela Merkel facing a stark choice between forming a minority government or calling for a new election. But would a minority government necessarily be as bad as Germans have traditionally thought?

    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.

    The Platform Economy

    While developed countries in Europe, North America, and Asia are rapidly aging, emerging economies are predominantly youthful. Nigerian, Indonesian, and Vietnamese young people will shape global work trends at an increasingly rapid pace, bringing to bear their experience in dynamic informal markets on a tech-enabled gig economy.

    Profiles in Discouragement

    One day, the United States will turn the page on Donald Trump. But, as Americans prepare to observe their Thanksgiving holiday, they should reflect that their country's culture and global standing will never recover fully from the wounds that his presidency is inflicting on them.

    How Women Shape Coups

    In Zimbabwe, as in all coups, much behind-the-scenes plotting continues to take place in the aftermath of the military's overthrow of President Robert Mugabe. But who the eventual winners and losers are may depend, among other things, on the gender of the plotters.

    The Abnormality of Oil

    At the 2017 Abu Dhabi Petroleum Exhibition and Conference, the consensus among industry executives was that oil prices will still be around $60 per barrel in November 2018. But there is evidence to suggest that the uptick in global growth and developments in Saudi Arabia will push the price as high as $80 in the meantime.

    The Saudi Prince’s Dangerous War Games

    Saudi Arabia’s Crown Prince Mohammed bin Salman is working hard to consolidate power and establish his country as the Middle East’s only hegemon. But his efforts – which include an attempt to trigger a war between Israel and Hezbollah in Lebanon – increasingly look like the work of an immature gambler.
