December 2014 was a record breaking month for UK wind power. A total of 3.90 TWh of electricity was generated in the month – supplying 13.9% of the UK's electricity demand. On 19 October 2014, wind power supplied just under 20% of the UK's electrical energy that day. Additionally, as a result of eight of 16 nuclear reactors being offline for maintenance or repair, wind produced more energy than nuclear did that day. The week starting 16 December 2013, wind generated a recor. [pdf]

.
A wind turbine turns wind energy into electricity using the aerodynamic force from the rotor blades, which work like an airplane wing or helicopter rotor blade..
Wind turbines use blades to collect the wind's kinetic energy. Wind flows over the blades creating lift (similar to the effect on airplane wings), which causes the blades to turn..
It involves using wind turbines to convert the turning motion of blades, pushed by moving air (kinetic energy) into electrical energy (electricity)..
Wind turbines, as they are now called, collect and convert the kinetic energy that wind produces into electricity to help power the grid. Wind energy is actually a byproduct of the sun. [pdf]
