Novo Nordisk ($NVO), the Danish maker of insulin, said all of its global manufacturing facilities will run on electricity generated from renewable sources by 2020. Currently, the company's facilities in Denmark, Brazil and Japan use electricity from renewable sources, and last month its facilities in Tianjin, China, signed an agreement to buy electricity from a windmill farm based in Mongolia. Novo Nordisk says it will reach similar agreements in the coming years for its plants in the U.S., France, Russia, Algeria and Iran. Story
