Wind energy refers to the power that is extracted from the wind via wind turbines or windmills. As the technology in this field evolve, the cost of wind generated electric power continues to fall and the efficiency continue to increase. It has been estimated that the cost to produce energy from wind was nearly five greater in the late 1990s than in 2005. This is linked to more efficient wind turbines couples with larger multi-megawatt turbines that are becoming more mass produced.
