anything that moves has kinetic energy, wind turbines are used to harness the kinetic energy of wind.
wind blows across the blades of a wind turbine thus forcing the blades to move which creates kinetic energy that is then harnessed by the turbine.
once the energy is generated it can be connected to a power grid to be used elsewhere.
one wind turbine has the capability of generating enough power for a single home while a wind farm can produce enough electricity for thousands of homes.
“Wind is renewable. Turbines are not.” -Ozzie Zehner (Green Illusions)
