Summary
Functional unit: 
1kWh of electricity delivered to the grid by a 50MW wind power plant
Goal and scope of the summary: 
The goal of the cradle-to-grave LCA study is to evaluate the potential environmental impacts associated with the production of electricity from a 50MW onshore wind plant, comprised of 25 V110-2.0 wind turbines (those turbines were launched for sale in AUgust 2014).
The energy required to produce a V11062.0 turbine is paid back 31 times over the turbine life-cycle (20 year- life cycle) on low wind conditions. 

The raw materials production and the end-of-lif of the turbines (final disposal of the turbines, reusing or recycling of materials), dominate the environmental impacts, accross all impacts categories. Transports, operation, maintenance, installation and servicing are less significant.
