Wind Power Generation
Wind power generation is the most widely used way to use wind energy in modern times. Wind power generation systems have shorter set-up time and can work continuously if the wind speed is enough [31–33] g. 5 is the typical framework of a wind power generation system. For a wind power generation system, the wind turbine is a critical part.
5 Top Wind Turbines for Low Wind Speeds
The first thing you need to know is that wind power is proportional to the cube of wind speed, meaning that if a turbine generates 1 KW at 10 mph, that same turbine will generate 8 KW at 20 mph (double the wind speed 3 = 2 x 2 x 2). That''s the reality of wind energy. Luckily, newer wind turbines are designed to work in wind speeds as low as 0
