Energy conversion - Windmills, Turbines, Renewable: Windmills, like waterwheels, were among the original prime movers that replaced animal muscle as a source of power. They were used for centuries in various parts of the world, converting the energy of the wind into mechanical energy for grinding grain, pumping water, and draining lowland areas.
Wind power or wind energy is a form of renewable energy that harnesses the power of the wind to generate electricity. It involves using wind turbines to convert the turning motion of blades, pushed by moving air (kinetic energy) into electrical energy (electricity). This requires certain technologies, such as a generator that sits at the top of

Each of these turbines consists of a set of blades, a box beside them called a nacelle and a shaft. The wind – even just a gentle breeze – makes the blades spin, creating kinetic energy. The blades rotating in this way then also make the shaft in the nacelle turn and a generator in the nacelle converts this kinetic energy into electrical
Small wind energy systems can be connected to the electricity distribution system. These are called grid-connected systems. A grid-connected wind turbine can reduce your consumption of utility-supplied electricity for lighting, appliances, electric heating and cooling, and vehicle charging. If the turbine cannot deliver the amount of energy you

A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade. When wind flows across the blade, the air pressure on one side of the blade decreases. The difference in air pressure across the two sides of the blade creates both lift and drag.
Below, we explore 12 common types of wind turbines used in the field of renewable energy. 1. Horizontal-Axis Wind Turbines (HAWTs) The most common type of wind turbine is the Horizontal-Axis Wind Turbine (HAWT). These turbines have a main rotor shaft and electrical generator at the top of a tower, and must be pointed into the wind.
