Wind power is a clean, emissions-free power generation technology.
Like all renewable sources it is based on capturing the energy from natural
forces and has none of the polluting effects associated with ‘conventional’
fuels. The development of wind power will help slow down the effects of
Wind is a global power source.
source twenty years
ago, wind energy has
mushroomed into a mature and
booming global business. Generating costs have
fallen dramatically over the last 15 years, moving closer
to the cost of conventional energy sources. Modern wind
turbines have improved dramatically in their power rating, efficiency and
There is a large and growing global demand for emissions-free wind power,
which can be installed quickly, virtually anywhere in the world with
appropriate wind conditions
Over the past ten years, global wind power capacity has continued to grow at
an average cumulative rate of over 24%. In 2009 as in 2010, new installed
capacity exceeded 38 GW (gigawatts) per year reaching a total of almost
200GW. For the first time in history, in 2010, more wind power capacity was
installed in developing economies than in fully developed countries, the latter
being the traditional markets for wind energy.
China has become the leader of installed wind power capacity, followed by
the United States, Germany and Spain. Brazil and Mexico are Latin American
leaders of installed windpower capacity reaching in 2010, a total of 930 and
519 MW respectively.
Worldwide, in 2010, the investments in renewable energy reached $210
billion dollars, 31.8% higher than the previous year. Also, for the first time the
investment in renewable energy exceeded investments based on fossil fuel. The global growth of wind power is expected to continue rising at this
