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.

The 12 Largest Wind Energy Companies In The World, And What They Do FAQs (Frequently Asked Questions) 

How many homes can a megawatt (MW) of electricity power?

One megawatt (MW) is one thousand kilowatts or a million watts of power. This is enough energy to power 200 to 750 homes, depending on their size and consumption.

How many homes can a gigawatt (GW) of electricity power?

One gigawatt (GW) is one million kilowatts or a billion watts of power. This is enough energy to power between 200,000 and one million homes, depending on their size and consumption.

What factors affect the amount of power a wind turbine generates?

The amount of power generated by a wind turbine depends on:

  • the height of the turbine from the ground
  • the rotor area
  • the blade radius of the wind turbine
  • the location of the wind turbine – particularly onshore vs. offshore and the presence of obstructions
  • air density in the wind turbine’s location

the theoretical maximum efficiency for the wind turbine, known as the Betz limit

How much of the world’s electricity is generated from wind?

Wind energy is the leading non-hydro renewable energy technology. In 2020 wind energy supplied 1592 TWh of electricity which was 5% of global electricity generation and 2% of electricity consumption. This is more than the other renewable energy sources combined.

What are the disadvantages of wind energy?

Though wind energy is a low-emissions energy source, it has several practical and environmental disadvantages. Downsides of wind energy include:

  1. The rotating blades of wind turbines can kill migratory birds and bats
  2. Wind turbines can create noise pollution if sited close to residential areas
  3. The movement of the blades can change surface air temperature. 
  4. Wind availability is inconsistent, therefore wind turbines do not provide a continuous supply of electricity. 
  5. Wind turbines create a ‘shadow flicker phenomenon. This is where the rotor blades cast intermittent shadows in properties close to the turbines. 
  6. Wind energy has high upfront costs, including land acquisition and surveying, site development, and the fabrication and installation of suitable wind turbines.

What is Onshore wind?

Onshore wind is wind energy generation on land rather than out at sea. Wind energy companies install onshore wind farms in suitable areas with low habitat value. Onshore wind generation is quicker, easier, and cheaper to install than offshore wind and there is less voltage drop between the wind turbine and the end user. However, onshore wind speeds are less predictable than offshore wind, impacting the consistency of power generation.

What is Offshore wind?

Offshore wind energy generation takes on bodies of water, to take advantage of higher and more consistent wind speeds that are available, in the absence of physical obstructions. Offshore turbines are larger and more powerful than an onshore wind turbine. But installing offshore wind farms is expensive and complex, costing at least 20% more than onshore wind farms. Turbines installed out at sea are vulnerable to corrosion and increased maintenance needs.
