sustainabilty

• sustainability is

   protecting the environment and resources for the future.

  
• Wind energy is a 

  renewable source.

  
• Wind is caused by the Sun warming air more in some areas than others


  , causing it to move.

  
•  As long as the Sun lights the Earth,

  wind will not run out.

  
• Wind power is sustainable because it releases 

  no greenhouse gases or pollution,

  
• The negative impact of wind farms is down to their local impact 

  if they disturb or damage local wildlife or habitats. 

  
• the manufacture and transport of turbines can also have an

  impact. 

  
• The towers are made of steel which is made using

  coal

  
• The blades are made from composite materials like carbon fibre 


  which can be difficult to recycle.
