Wind turbines are good alternative of solar panels with the highest effeciency.In obviously windy climates ,Venturbine Micro Wind Turbines generates %89 efficiency by nonstop working.

Wind turbines use energy from the wind, using mechanical power to turn a generator and generate electricity. While wind is an abundant and inexhaustible resource, it also provides electricity of course without burning any fuel or polluting the air.

It is obvious big turbines generates more energy that micro ones,but these are for industrial purposes.In household energy usage ,micro turbines always helps to cover big percentage of electric energy usage of houses monthy.Wind turbines can also be combined with solar panels.In that way,houses will generate energy from both solar panels and small wind turbines.

Once water pressure is planned to move a mechanical component, this action starts the potential energy of the water to be converted into mechanical energy. Therefore hydro turbines convert water pressure into mechanical shaft power that can be used to drive an electric generator.

Standard wind turbines with blades and horizontal axis.

The common horizontal axis wind turbine models use three blades, the most efficient solution.

Wind turbines catch the wind's renewable energy with their propeller-like blades, that act just as an airplane wing. While the wind blows, a pocket of low-pressure air forms on one side of the blade. The low-pressure air pocket then pulls the blade toward it, causing the rotor to turn

In small wind turbines , 3-kilowatt wind turbine will meet the needs of a home requiring 300 kilowatt-hours per month in a location with 14 mile (22 km /h) -per-hour (6.26 meters-per-second) annual average wind speed. A professional installer will assist you determine what size turbine you be best based on your elektricity need and usage.In general ,some countries limits the wind turbines installation with a maximum limit and features.

As the blades of the turbines rotate in the direction of the wind, electromagnetic induction occurs within the magnetic field of the permanent magnet in the turbines to produce electricity. A generator connected to the shaft of the wind turbine converts the motion of the blades to electricity.

In genuily speaking micro wind turbines for household usage,The wind even just a small breeze generates the blades spin, creating kinetic energy. In this way ,the blades rotating then also make the shaft in the nacelle turn and a generator in the nacelle converts this kinetic energy into electrical energy.
