Wind

• Wind energy has been used for thousands of years, and before the advent if steam power, windmills were a very common sight scattered across the countryside
• Today we use tall towers with propeller-like blades driving a generator. Although sometimes found as single towers, more often they are grouped together to form a 'wind farm'. You might also see much smaller versions attached to caravans or boats to charge their batteries

  
• The best places to put wind tubines are on the coast, offshore, on a hill, or between hills or mountains, so that the wind supply is reliable

  
• As the blades are so long the tower on the wind turbine needs to be very high, but the land underneath can still be used
