Suzlon Energy, India's champion of the wind industry, has just announced plans to invest Rs 15 billion (that's $326 million) into expanding manufacturing capacity.

I used to think that for manufacturers of large wind turbines for export over any great distance would be next to impossible. They are simply too huge and cumbersome. That was and is certainly true of German manufacturers. But Suzlon by manufacturing in India is turning this idea on its head. They are selling into the USA from India - very impressive. Just yesterday, the company also got a Rs 11.9 billion ($258m) order from US-based John Deere Wind Energy to supply 247 MW of wind turbine capacity. That's actually a good price for John Deere - wind turbine capacity has risen substantially from a few years ago from $1m per megawatt to $1.2 - $1.3. The rise has been due to the increase in raw materials like steel that go into the turbine towers.
