Die britische Schiefergas-Chance

PRAG – Ende Juni gab der britische Geological Survey die Entdeckung des weltweit größten Schiefergasfeldes bekannt. Das Bowland-Shale-Feld zwischen Lancashire und Yorkshire enthält 50% mehr Gas als zwei der größten Felder in den Vereinigten Staaten zusammen, das Barnett Shale und das Marcellus Shale.

Großbritannien hat bisher gezögert, sich der Revolution des hydraulischen Aufbrechens (oder Frackings) anzuschließen. Aber eine Ausbeutung des Bowland Shale könnte die britische Wirtschaft wieder ankurbeln und die CO2-Emissionen deutlich verringern.

Das britische Parlament hat neue Maßnahmen zur Reduzierung der Kohlenstoffemissionen bis 2020 beschlossen. Die mit Abstand größten Einsparungen dabei werden durch eine Steigerung der Anzahl der Offshore-Windkraftanlagen um 800% über die nächsten sieben Jahre erreicht. Aber Offshore-Windkraft ist so teuer, dass sie mindestens das Dreifache der normalen Stromkosten als Subventionen erfordert – sogar mehr als Solarenergie, die in Großbritannien noch nie populär war. Eine nur geringe CO2-Einsparung würde Großbritannien sehr teuer zu stehen kommen.

  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.

    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.

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.
