When the wind blows, the wind turbine's blades spin clockwise, capturing energy of the wind. This triggers the main shaft of the wind turbine, connected to a gearbox within the nacelle, to spin. The gearbox sends that energy to the generator, converting it to electricity. Wind …Collecting and Storing Energy from Wind Turbines. Due to the finite nature of non-renewable energy sources and the increasingly pronounced effects of climate change, securing alternative power sources is becoming a huge issue. One solution is wind turbines which convert the kinetic energy of the wind into electric energy for consumption.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.Jets, Wakes, and Power Changes. One poorly captured boundary-layer wind feature is the nocturnal jet, which is essentially a tube of fast-moving wind that appears at night at a height of between 150 and 500 m—the same height as the center of a turbine’s rotor. The jets are caused by a rapid cooling of Earth’s surface after sunset, and the ...Offshore wind turbines are designed to last up to 30 to 35 years at sea, but there is currently no proof of how large turbines will react to their environment (wind and waves). “We don’t have any long term examples of this,” Prendergast said. “This is a problem that hasn’t occurred yet.
