Siemens, the largest such enterprise in Europe, has announced that it will stop any investment in nuclear power. The sustainable energy unit of the firm had the strongest growth in 2010 among all lines of its businesses.
With €28 billion in revenue, Siemens’ environmental technologies sector is currently one of the largest in the world.

Our heartfelt salute, Siemens, for making responsible eco-friendly decisions. May green technology, combined with the Earth-saving vegan diet, bring us to a glorious era of our planet.
