迷你电网的力量

哈拉雷—尽管在近几年来取得了令人印象深刻的经济发展成就,但非洲仍然在能源方面远远落后,近三分之二的非洲公民用不上电。让人民用上更多的电是一个重要的目标,但扩张电网费钱又费时。与此同时,网下选择也无法满足人民的能源需要。幸运的是,有第三条道路可以帮助填补空白:迷你电网。

迷你电网本质上是本地化的电力网络,可供应多个用户,包括家庭和企业。它们可以与电网相连,但非必须。非洲进步委员会(Africa Progress Panel,本文作者之一是其中的成员)的最新报告指出——并获得了落基山研究所(Rocky Mountain Institute)的一份报告的印证——迷你电网是非洲能源拼图的重要一块。

迷你电网较之将电网扩大到农村和偏远地区拥有巨大的竞争优势,因为它们可以以更快的速度和更低的成本供电。迷你电网所需要的资本投资要小于电网扩张,因此更容易确保融资,这意味着它们可以为原本需要等待多年才能接入电网的社区提供电力。

    Empowering China’s New Miracle Workers

    China’s success in the next five years will depend largely on how well the government manages the tensions underlying its complex agenda. In particular, China’s leaders will need to balance a muscular Communist Party, setting standards and protecting the public interest, with an empowered market, driving the economy into the future.

    The Sovereignty that Really Matters

    The preference of some countries to isolate themselves within their borders is anachronistic and self-defeating, but it would be a serious mistake for others, fearing contagion, to respond by imposing strict isolation. Even in states that have succumbed to reductionist discourses, much of the population has not.

    Resurrecting Creditor Adjustment

    When the Bretton Woods Agreement was hashed out in 1944, it was agreed that countries with current-account deficits should be able to limit temporarily purchases of goods from countries running surpluses. In the ensuing 73 years, the so-called "scarce-currency clause" has been largely forgotten; but it may be time to bring it back.

    Trump’s Republican Collaborators

    Republican leaders have a choice: they can either continue to collaborate with President Donald Trump, thereby courting disaster, or they can renounce him, finally putting their country’s democracy ahead of loyalty to their party tribe. They are hardly the first politicians to face such a decision.

    How Money Could Unblock the Brexit Talks

    With talks on the UK's withdrawal from the EU stalled, negotiators should shift to the temporary “transition” Prime Minister Theresa May officially requested last month. Above all, the negotiators should focus immediately on the British budget contributions that will be required to make an orderly transition possible.

    Is Vladimir Putin Losing His Grip?

    In recent decades, as President Vladimir Putin has entrenched his authority, Russia has seemed to be moving backward socially and economically. But while the Kremlin knows that it must reverse this trajectory, genuine reform would be incompatible with the kleptocratic character of Putin’s regime.

    Don’t Bank on Bankruptcy for Banks

    As a part of their efforts to roll back the 2010 Dodd-Frank Act, congressional Republicans have approved a measure that would have courts, rather than regulators, oversee megabank bankruptcies. It is now up to the Trump administration to decide if it wants to set the stage for a repeat of the Lehman Brothers collapse in 2008.
