Der Energiesicherheit steht eine Eiszeit bevor

Die weltweite Abhängigkeit von fossilen Brennstoffen ist wesentlich kostspieliger als der Preis eines Barrels Rohöl. Die aktuelle Krise im Nahen Osten, die allmähliche Umwandlung Zentralasiens in einen militärischen Vorposten des Westens und schwache Regime wie Russland und Venezuela unter den anderen wichtigen Produzenten, erinnern auf ernüchternde Art an die Fragilität der globalen Energiesicherheit.

Die Weltwirtschaft wird bis weit in dieses Jahrhundert hinein von fossilen Brennstoffen abhängig bleiben und ihre Verwundbarkeit wird in der absehbaren Zukunft noch zunehmen. Die Einsparung von Energie kann den steigenden Verbrauch der Industriestaaten und der Entwicklungsländern zwar mäßigen aber nicht umkehren. Erneuerbare Energien sind vielversprechend, werden aber so bald keinen Ersatz für fossile Brennstoffe bieten.

Dennoch gibt es Hoffnung auf eine reiche, saubere Energiequelle, die die globale Sicherheit enorm verstärken würde, indem sie die Produktion näher an den Verbraucher rückt. Überraschenderweise ist diese Energiequelle eine Form von Eis. Wenn Erdgas aus dem inneren der Erde nach oben dringt und sich unter bestimmten Gegebenheiten wie niedrige Temperatur und hoher Druck auf und unterhalb des Meeresbodens mit Wasser verbindet, entsteht Gashydrat - eine Substanz von der die meisten Menschen noch nie gehört haben, die aber geologisch durchaus üblich ist. Nach der Freisetzung des Gases aus dem gefrorenen Wasser, kann es in Speichern aufgefangen und genau wie normales Erdgas in Pipelines transportiert werden.

    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.
