The ‘design’ life of a wind turbine is usually 20 years. Wind power is a relatively new industry, however, so there are actually very few machines that have reached that age yet. Some turbines in Germany and Denmark have been spinning quite happily well past their 20 year design life…while others have been replaced before the end of their design life because the technology has evolved so rapidly.
How long does a wind turbine work for?
