Last month Hanson Transmissions International, a maker of gearboxes for wind turbines, was listed on the London Stock Exchange. Nothing noteworthy about that, you might say, despite the jump in the share price on the first day of trading and the handsome gain since: green technology is all the rage, is it not But Hanson exemplifies another trend too, which should prove every bit as durable: the rise of multinational companies from emerging economies. Its parent is Suzlon, an Indian firm that began life as a textile manufacturer but is now among the world’s five leading makers of wind turbines. Along the way, Suzlon has acquired not only Hanson, originally Belgian, but also REpower, a German wind-energy firm, spending over $ 2 billion on the pair.
