There are two main types of wind turbines: horizontal-axis turbines and vertical-axis turbines. Horizontal-axis turbines, with three blades rotating around a horizontal axis, are the most common. They can be either upwind or downwind, depending on the position of the blades relative to the tower. Vertical-axis turbines, on the other hand, come in various designs and are omnidirectional.

Wind turbines can be installed on land or offshore, offering flexibility in location. They vary in size, from small turbines designed for individual use to large utility-scale turbines that contribute to the grid. The electricity generated by wind turbines can be connected to the grid or used privately, depending on the needs and preferences of the energy consumer.

Wind farms are groups of wind turbines working together to produce renewable energy. They are strategically located in areas with favorable wind conditions to optimize power generation. The first wind turbine that produced electricity was developed in Scotland in 1887, and the US opened its first wind farm in 1980, marking the beginning of a new era in sustainable energy production.

Despite concerns about bird populations, wind farms have a relatively small impact compared to other factors like cats and high-rise buildings. In fact, the UK has made significant strides in generating power from wind energy, highlighting its potential as a renewable energy source.
