Vestas Wind Systems is the largest manufacturer of wind turbines and systems in the world.^[1] Since 1979 the company has installed over 40,000 wind turbines in 65 countries with a total capacity of 38.3 GW.^[2][3] Wind systems get more cost-efficient as they grow in size and scale, making them ideal for large-scale installations; Vestas is one of the few manufacturers that makes turbines that produce as much as 3.0 MW.

With issues like energy independence, climate change, and high oil prices (WTI crude peaking at $124 in 2008) driving legislation that mandates and subsidizes the use of renewable energy sources, wind energy is cheaper than it has been in the past.^[4] Accounting for subsidies for wind farm construction, the installation cost of large wind farms rivals that of traditional gas and coal plants, giving the wind market an advantage over other renewables. Without subsidies, wind is still more expensive than cheap coal in low-regulation regions; for this reason, Vestas was forced to abandon its Australian operations.
