Since their inception in the late 1880s, wind turbines have evolved dramatically, with heights increasing from 100 meters to over 245 meters in the last two decades. Modern turbines, particularly offshore models, now can generate up to 18 megawatts of electricity. This growth is driven by improved efficiency at greater altitudes where wind speeds are stronger and more consistent. Innovations like low-wind turbines allow energy production in regions previously deemed unsuitable, enhancing the overall economic and geographical viability of wind energy.
Wind speeds are both stronger and more consistent at higher altitudes, which equals greater electricity production. Taller towers also allow for longer rotor blades, capturing more wind.
Researchers have calculated that these new models could significantly expand the geographical reach of wind energy, making it useful in regions not considered suitable.
When there is a lot of production, or wind power, then electricity prices go down, meaning your income as a wind turbine owner goes down.
Larger blades are more easily set in motion by low-speed winds, making them economically interesting to manufacturers despite the higher setup costs.
