<span>Wind power is produced from the
wind turbines or sails that uses air flow to convert it into mechanical power. It
is an alternative to fossil fuel burning, it is all around, renewable, clean,
produces no greenhouse gases and uses little land. The advantages of wind power
have been greatly praised by many. However, it has disadvantages. Wind power
especially at farm is noisy and may spoil the view for their neighboring people.
Also the amount of electricity depends on the strength of the wind. If no wind
is around, no electricity is produced. </span>
