Wind is a beneficial resource because it is a no-emissions energy source, so it produces no air or water pollution. Its operational costs are pretty low as wind is free. Wind energy is very efficient. Wind power is considered as a renewable energy resource. This means that the power generated from wind is replenished by the environment over relatively short periods of time.

India’s power sector is huge. It derives its power from diverse sources like hydro power, solar power, bio gas energy, wind power, thermal power, etc. Like all the other states in India, Andhra Pradesh has power generation plants. Andhra Pradesh thermal power plants form an important part of the power generating capacity of Andhra Pradesh. Thermal Power in Andhra Pradesh is mostly generated through gas, coal, and oil. The electric power of the state is generated at the thermal power plants of Andhra Pradesh, which meets the electricity needs of the state.
