Der Anbau von Energie

Vom Klimawandel bis zu schwankenden Ölpreisen deuten alle Anzeichen auf eine bevorstehende globale Energiekrise hin. Sich dieser ständig größer werdenden Herausforderung zu stellen, heißt, dass es sich die Menschheit nicht mehr leisten kann, jene unerschöpfliche, in organischem Material lagernde Ressource zu ignorieren, die uns von der Sonne über den Weg der Photosynthese jeden Tag zur Verfügung gestellt wird. Sonnenenergie ermöglicht es Pflanzen, Kohlendioxid aufzunehmen und dabei nicht nur Sauerstoff, sondern auch Material zu produzieren, das im Tierreich als Futter dient – und unseren Maschinen Energie liefert.

Seit dem Neolithikum (Jungsteinzeit) haben Menschen diese „Biomasse“ angebaut, um sich zu ernähren. Dennoch wird dieses Energiepotenzial in der Welt von heute ignoriert. Seit Beginn der industriellen Revolution war die Menschheit darauf aus, Energie aus Kohle und später aus Öl und Erdgas zu gewinnen, was allerdings zur Erschöpfung nicht erneuerbarer Ressourcen führt.

Alternativen zur Diversifizierung der Energieproduktion sind begrenzt. Atomenergie hat einige Nachteile, die sich aus Bedenken hinsichtlich ihrer Sicherheit und der Lagerung radioaktiven Abfalls ergeben. Wasserkraft wird zwar verbreitet genutzt, Wind- und Solarenergie wird jedoch aus strukturellen Gründen nur spärlich produziert und ist auch nicht überall im gleichen Ausmaß verfügbar.

    The Brexit Surrender

    European Union leaders meeting in Brussels have given the go-ahead to talks with Britain on post-Brexit trade relations. But, as European Council President Donald Tusk has said, the most difficult challenge – forging a workable deal that secures broad political support on both sides – still lies ahead.

  2. The Great US Tax Debate

    ROBERT J. BARRO vs. JASON FURMAN & LAWRENCE H. SUMMERS on the impact of the GOP tax  overhaul.


    • Congressional Republicans are finalizing a tax-reform package that will reshape the business environment by lowering the corporate-tax rate and overhauling deductions. 

    • But will the plan's far-reaching changes provide the boost to investment and growth that its backers promise?

  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.
