"Wir sind - relativ gesehen - der größte Produzent von Strom aus erneuerbaren Energiequellen. Das is eine gute Sache, und wir müssen jetzt noch von 80 auf 100 Prozent kommen."DW-TV: Island ist ein Energieparadies. Die Energie kommt einfach so aus dem Boden, aber ganz so einfach ist es nicht, und darüber möchte ich mit dem Leiter des Innovationszentrums Island, Thorsteinn Sigfusson, sprechen. Die ganz Welt beschäftigt sich mit Energiesparen. Hier auf Island scheint man das gar nicht nötig zu haben? Thorsteinn Sigfusson: Das würde ich so nicht sagen, aber wir haben schon eine Menge Energie. Sie kommt aus dem Boden, sie kommt aus den Flüssen, und sie steckt natürlich im Wind. Wir haben also wirklich viel davon. Im Moment stammen 80 Prozent unserer Primärenergie aus erneuerbaren Quellen, das ist der höchste Prozentsatz von allen Ländern. 80 Prozent klingt natürlich fantastisch, in Deutschland haben wir ungefähr 16,5 Prozent nur erneuerbare Energie bei der Stromerzeugung. Andererseits muss man sagen, wo die Energie hier im Überfluß zu haben ist, warum nicht 100 Prozent? Wir leisten uns in Island einen sehr aufwändigen Lebenswandel. Wir fahren schwere Autos mit Allradantrieb, wir haben vielleicht sogar drei Autos pro Haushalt. Dann produzieren wir Aluminium mit elektrischem Strom: Das Aluminium-Schmelzen verbraucht eine Menge Kohlenstoffhaltige Elektroden, auch das erzeugt wieder CO2. Also alles in allem: eine ziemlich schlechte CO2-Bilanz. Bedeutet das auch, dass die Menschen hier gar kein Bewusstsein dafür haben, Energie zu sparen? Gibt es eine Möglichkeit, sich hier umzustellen und von den hohen Belastungen bei den CO2-Emmissionen von achtzehn Tonnen im Jahr heute herunterzukommen? Das ist natürlich eine der Herausforderungen, die vor uns liegen. Zum Beispiel haben wir daran gearbeitet, wie man Wasserstoff mit erneuerbarer Energie herstellen kann, durch Hydrolyse, also durch das Aufspalten von Wasser, und wie man diesen Wasserstoff dann zum Autofahren benutzen kann...
