Wind energy is kinetic energy of wind exploited for electricity generation in wind turbines.
Wind power experienced dramatic growth since the turn of the 21st century. Global installed capacity at the end of 2011 was around 238 GW, up from 18 GW at the end of the year 2000. Around 41 GW was added in 2011 alone. Over the last couple of years, wind’s centre of growth moved from Europe and North America to Asia, which emerged as the global leader. China became the global leader in terms of total installed capacity in a very short time, overtaking the United States in 2010. A number of recent important policy measures and programmes have emerged in support of expanded wind markets, and many of the new policy developments concern offshore wind. Ten European countries have agreed to develop an offshore electricity grid in the North Sea to enable offshore wind developments.
