The contemporary equivalent of a windmill is a wind turbine. Simply said, they generate electricity by harnessing the power of the wind. Although large wind turbines are the most noticeable, you can also purchase a tiny wind turbine for personal use, such as to power a caravan or boat.
How Wind Turbine works ?
The basic operation of a wind turbine is as follows: the wind turns the blades, which rotates the axis, which is connected to a generator, which generates DC electricity, which is then converted to AC electricity by an inverter and used to power your home. The stronger the wind, the more electricity is generated by the motion.
Because of this, industrial-scale wind farms with tall towers and substantial blades are frequently found in the countryside windiest locales, including offshore. The effectiveness of a turbine is determined by how well it can capture wind energy, convert it into rotational torque, and then propel electrons from the generator into the grid. The blades, which must be robust yet lightweight to turn in the wind, can be constructed of glass fibre or reinforced polyester, while the towers are typically made of steel.
A single 1.8 MW wind turbine running at normal capacity will produce enough electricity in a year to feed 1,000 average homes. The Whitelee Wind Farm in Scotland has 140 turbines that provide electricity for around 180,000 homes.
