How is it that Philadelphia, Pennsylvania's largest city, has become a location of choice for 2 leading listed european alternative energy companies?

We're talking about Gamesa Corp and Conergy AG.

Said Governor Rendell of Penn State;

"Pennsylvania has aggressively pursued a leadership role in advancing the technology and deployment of alternative fuels in order to build a dynamic new commercial sector that diversifies our energy supplies and puts people to work . . . these strategic investments will move us further down the road to true energy security for the people and businesses of Pennsylvania."

What this really means is that they are offering a lot of government support - so be it. But the bigger story is that European alternative companies are becoming increasingly aware that they have got to have a presence in the American market and manufacturing facilities in the Far East.

Relying on the European market for sales and production is anything but a good bet for the future.
