GE to buy wind turbine rotor blades maker for $1.65bn

General Electric said it would buy LM Wind Power, a maker of rotor blades used in wind turbines, from private equity firm Doughty Hanson for $1.65-billion, as it looks to capture a bigger share of the fast-growing renewable energy market. GE separated its renewable energy business from its power unit last year, following the $13.6-billion acquisition of Alstom's power business.
