太阳能价格革命

波茨坦—一场静悄悄的革命正在进行中。11月,迪拜宣布将建设一个太阳能工场,以不到每千瓦时0.06美元的价格发电,低于其他投资选择——天然气或煤电的成本。

该发电厂——预计将于2017年投入运营——是未来可再生能源扼杀传统化石燃料的又一先遣队。事实上,几乎每个星期都会有大型新太阳能发电厂要兴建的消息。光是在2月,就有尼日利亚 (1,000百万瓦)澳大利亚(2,000百万瓦)和印度(10,000百万瓦)等新项目公布。

毫无疑问,这些发展趋势有利于遏制气候变化。但驱动这些投资的主要考虑因素是利润而不是环境,因为能源分销和储藏(如有必要)效率的提高降低了生产可再生能源的成本。

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations.

  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.

    The Holy Grail of Genetic Engineering

    CRISPR-Cas – a gene-editing technique that is far more precise and efficient than any that has come before it – is poised to change the world. 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.
