Reported symptoms include headaches, nausea, sleep problems, night terrors, tinnitus, irritability, anxiety, concentration and memory problems, and issues with equilibrium and dizziness.
Wind turbines allow us to harness the power of the wind and turn it into energy. 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 …
