Text Over the past 25 years global wind energy capacity has doubled every three
years, corresponding to a tenfold expansion every decade. By the end of 2010
global installed wind capacity was approximately 200 GW and in 2011 is
expected to produce about 2% of global electricity consumption.
The huge potential of wind, the rapid development of the technology and the
impressive growth of the industry justify the perception that wind energy is
changing its role to become the future backbone of a secure global energy
Between the mid-1980s, when the wind industry took off, and 2005 wind turbine
technology has seen rapid development, leading to impressive increases in the
size of turbines, with corresponding cost reductions.
From 2005 to 2009 the industry’s focus seems to have been on increasing
manufacturing capacity, meeting market demand and making wind turbines more
reliable. The development of new and larger turbines to some extent stagnated,
and costs even rose due to high demand and rising materials costs.
We believe, however – and this is supported by recent trends – that the next
decade will be a new period of technology development and further scale-up,
leading to more cost-effective, reliable and controllable wind turbines and
new applications. This is partly due to increased international competition,
but also because the industry is increasingly dominated by high-technology
international companies. The move to install more capacity offshore also
favours larger wind turbines and encourages new ways of thinking.
In this paper we discuss the current status of wind power and its prospects up
to 2050, including both existing and emerging technologies.
