Day 37. Wind.

If one were to boil down the Danish economy into its four most profitable exports, it'd look something like this:

• Diabetes medication
• Oil (thanks to these guys)
• Pork
• Wind energy machinery

Since I'm probably not allowed in Novo Nordisk's laboratories with a camera, and I'd rather not visit a slaughterhouse or an oil rig, you get to read about wind energy. Vestas, based in Aarhus, is the world's largest producer of wind turbines and one of the country's largest corporations. Given the nation's love for all things eco-friendly, the company's footprint is everywhere in – and around – Denmark.

(Legos, incidentally, would be number eight on that list.)
