Reuters:  Denmark's Vestas, the world's largest wind turbine maker, is keen to expand into areas such as energy storage to increase the global use of wind power and bring costs down.

The wind industry is entering a phase of slower growth and steadier demand for turbines, prompting producers to look at alternatives to grow revenue.

"The storage side is interesting and there are a lot of small start-ups that might be of interest. I’m looking for industry batteries," Vestas Chairman Bert Nordberg told Reuters.

"If you can store over-production in a good way it would take down the total cost."

Energy storage is the capture of energy produced for use at a later time, for instance in the form of batteries. The technology is becoming increasingly viable with the rise in sales of electric cars.  Full Article:
