Wind Energy:

Wind energy is a kinetic energy associated with movement Of large masses of air, they are clean, cheap, and eco-friendly renewable resource and is utilized as mechanical energy with the help of wind turbine. Wind speed is measured by an anemometer it’s Direction is measured by a wind vane attached to the director of indicator.

The Muppandal wind farm is India’s largest onshore wind farm. This project is located in Kanyakumari, Tamil Nadu. At present wind energy is used for pumping water and electricity.

How is wind energy is produced :

Energy in wind comes from the uneven solar heating of the atmosphere. The utilization of wind for energy goes back to the earliest sailing ships. On land, windmills applied the principle of sails to a rotary shaft, to reap the mechanical energy of wind for providing mechanical power. Small windmills on farms power water pumps, and a few were coupled to automobile generators to come up with electricity on the farm before the electrical distribution grid was built. Now huge wind turbines provide power for that grid.

Advantages and Disadvantages of Wind Energy.

There are some benefits in this system are a non-polluting and renewable source of energy. It avoids fuel explosion and transport. There are some disadvantages to these systems, they are noisy in operation, Birds and bats have been killed by the rotors. The installation and maintenance cost of a wind turbine is high. Fossil fuels pollute, are environmentally damaging, and running out fast, so we need alternatives.

TYPES OF WIND ENERGY

1. UTILITY-SCALE WIND ENERGY:

Utility-scale turbines are usually defined as turbines that exceed 100 kilowatts in size. Utility-scale wind turbines are typically installed in large, multi-turbine wind farms connected to the nation’s transmission system.

2.DISTRIBUTED WIND ENERGY:

Distributed wind energy systems are commonly installed on, but aren’t limited to, residential, agricultural, commercial, industrial, and community sites, and may home in size from a 5 kilowatt turbine at a home to multi-megawatt .

3.OFFSHORE WIND ENERGY:

Offshore wind generation or offshore wind energy is that the use of wind farms constructed in bodies of water, usually within the ocean, to reap wind energy to get electricity. Higher wind speeds are available offshore compared to ashore, so offshore wind power’s electricity generation is higher per amount of capacity installed, and NIMBY opposition to construction is typically much weaker.
