The 12 Largest Wind Energy Companies In The World, And What They Do

Discover profiles of the 12 largest wind energy companies in the world and what they do in the renewable energy sector in this informative guide. 

In the last decade, the push for domestic and international energy markets to use renewable sources of energy has led to massive growth in wind energy production. The global wind energy market is now worth at least $77 billion and energy sector analysts expect this to climb to a value of at least $132 billion by 2030.

Wind energy companies generate electricity from the movement of the rotor blades of wind turbines by the wind. A generator then converts this kinetic energy into electricity that can be fed into domestic or international energy grids. Demand for wind energy is increasing globally because governments and business leaders consider using wind for electricity generation sustainable, with a low environmental impact compared to conventional fossil fuel energy sources. 

In this article, we share the 12 largest wind energy companies in the world, and what they do. Read on for an informative profile of global wind companies whose activities span wind turbine manufacture, wind farms, and international investment in wind energy.
