Die Solarpreisrevolution

POTSDAM – Momentan findet eine stille Revolution statt. Im November kündigte Dubai den Bau eines Solarenergieparks an, der Elektrizität für unter 0,06 US-Dollar pro Kilowattstunde produziert – und damit alternative Investitionsmöglichkeiten wie solche in Gas- oder Kohlekraftwerke unterbietet.

Die Anlage – deren Fertigstellung für 2017 geplant ist – ist ein weiterer Vorbote einer Zukunft, in der erneuerbare Energien die konventionellen fossilen Energieträger verdrängt haben werden. Tatsächlich scheint kaum eine Woche zu vergehen, in der kein großer Vertrag über den Bau einer neuen Solaranlage bekannt wird. Allein im Februar gab es Ankündigungen über neue Solarprojekte in Nigeria (1.000 Megawatt), Australien (2.000 MW) und Indien (10.000 MW).

Darüber, dass diese Entwicklung beim Kampf gegen den Klimawandel hilft, besteht kein Zweifel. Aber die Hauptantriebskraft dahinter ist nicht die Umwelt, sondern der Profit, da die Kosten erneuerbarer Energien durch bessere Effizienz bei der Verteilung und eventuellen Speicherung von Energie sinken.

  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.
