The maximum amount of electricity that on-shore wind farms can produce is 200 kWh/d per person under ideal conditions i.e. covering the entire nation in wind turbines.
The following steps are taken in the energy conversion process while producing electricity from wind turbines:
First, the wind strikes the turbine blades and transfers its kinetic energy to them. A generator is attached to the turbine blades. The generator shaft is turned by the kinetic energy of the turbine blades.
The generator then produces electricity out of the kinetic energy of the blades.
