A wind turbine, or alternatively referred to as a wind energy converter, is a device that converts the wind's kinetic energy into electrical turbines are manufactured in a wide range of vertical and horizontal axis. The smallest turbines are used for applicatio such as battery charging for auxiliary power for boats or carava or to power traffic warning sig. Larger turbines can be used for making contributio to a domestic power supply while selling unused power back to the utility supplier via the electrical grid. Arrays of large turbines, known as wind farms, are becoming an increasingly important source of intermittent renewable energy and are used by many countries as part of a strategy to reduce their reliance on fossil fuels. One assessment claimed that, as of 2009, wind had the "lowest relative greenhouse gas emissio, the least water coumption demands and... the most favourable social impacts" compared to photovoltaic, hydro, geothermal, coal and gas
