The wind energy sector received its boom when wind turbine models up to 50 KW arrived in the market.   The technology trend in the wind industry kept continuously up scaling when wind turbines of capacities ranging from 200 to 500 KW became popular and then by the end of century, turbines of higher capacities were introduced .In the near future, wind turbines mainly dedicated to 2 - 3 MW capacity will be erected.

Wind turbines were made more sophisticated by applying third generation electronics and hydraulics. They were further modified and upgraded by using software and programmable inputs, which improved the performance and durability of the turbines. Automation and remote controlling were added features.
