renewable technologies - wind turbine
there are two main types of turbine, the horizontal and the vertical both operate in a similar manner but have a few differences.

the horizontal turbine needs to rotate to face into the wind like a traditional wind mill, the horizontal type can accept wind from any direction and therefore needs a smaller footprint.

because the vertical turbine spins on a vertical axis the majority of noise generated travels vertically making the vertical turbine quieter then the horizontal type.

wind turbines harness the power of the prevailing wind converting this into kinetic energy that rotates the blades, which in turn drives a generator, which produces useful electrical energy.   the amount of energy achievable is determined by the size of blade, rotation, speed and efficiency.  in excessive winds, turbines adopt a mechanical braking system or stop.

the electrical output from the wind turbine can be utilised in various ways the generator can be connected directly to the power grid, used for battery charging or connected to electric heating elements providing space or water heating.
the size and appearance of a wind turbine is typically large and will need to be considered by planning permission.  as the government is promoting the utilisation of wind power, there are some relaxations placed upon planning.
by utilising a wind turbine the CO2 emissions of the central generators can be offset, as the wind turbine does not create carbon emissions whilst operating. this system can be described as a true renewable source, and classed as zero carbon emission system.
